Toshiba Electronic Devices & Storage Corporation has expanded the lineup of 150V N-channel power MOSFETs with new six products that use the new generation process “U-MOSⅩ-H series.” Products in this series are suitable for the switching power supplies of industrial equipment such as data centers and communication base. The package of new products is a three-pin through hole type: TO-220 for “TK4R9E15Q5, TK7R2E15Q5 and TK9R6E15Q5” and TO-220SIS for “TK5R0A15Q5, TK7R4A15Q5 and TK9R7A15Q5.”
The new products use the U-MOSⅩ-H process to achieve low drain-source On-resistance. In particular, TK4R9E15Q5 features the excellent low drain-source On-resistance of 4.9mΩ (max). In addition, the new products uses high-speed diode (HSD) to improve reverse recovery characteristics, which are important for synchronous rectification applications, by reducing reverse recovery charge and faster reverse recovery time. Used in synchronous rectification applications, the new products reduce the power loss of switching power supplies and help improve efficiency.
The first product TPH9R00CQ5 which uses HSD, has approximately 74% less reverse recovery charge and approximately 44% faster reverse recovery time than Toshiba‘s existing product TPH9R00CQH, which does not use HSD. The U-MOSⅩ-H process using this HSD has applied to through hole type packages in addition to surface mount type packages.
The new products have reduced the drain source spike voltage generated between the drain and source when MOSFET is switching, helping to lower EMI in switching power supplies.

Affordability combined with high performance and efficiency is the key to making electric mobility accessible to a broader market. That’s why Infineon Technologies AG is introducing the HybridPACK™ Drive G2 Fusion, establishing a new power module standard for traction inverters in the e-mobility sector.
The HybridPACK Drive G2 Fusion is the first plug’n’play power module that implements a combination of Infineon’s silicon and silicon carbide (SiC) technologies. This cutting-edge solution provides an ideal balance between performance and cost efficiency, giving more choice in the optimization of inverters.
One of the main differences between silicon and SiC in power modules is that SiC has a higher thermal conductivity, breakdown voltage and switching speed, making it more efficient, but also more expensive than silicon-based power modules. With the new module, the SiC content per vehicle can be reduced, while maintaining vehicle performance and efficiency at a lower system cost. For example, system suppliers can realize nearly the system efficiency of a full SiC solution with only 30 percent SiC and 70 percent silicon area.
“Our new HybridPACK Drive G2 Fusion module underlines Infineon’s innovation leadership in the automotive semiconductor industry,” said Negar Soufi-Amlashi, Senior Vice President & General Manager High Voltage at Infineon’s Automotive division. “Addressing the demand for greater e-mobility range, this technological breakthrough smartly combines silicon carbide and silicon. Integrated in a well-introduced module package footprint it offers compelling cost-performance ratio over pure silicon carbide modules without adding system complexity for automotive system suppliers and vehicle manufacturers.”
HybridPACK Drive G2 Fusion expands Infineon’s HybridPACK Drive power module portfolio and can be quickly and easily integrated in vehicle components or modules without requiring complex adjustments or configurations. The HybridPACK Drive G2 Fusion module features up to 220 kW in the 750 V class. It ensures high reliability over the entire temperature range from -40 °C to +175 °C and improved thermal conductivity.
The unique properties of Infineon’s CoolSiC™ technology and its silicon IGBT EDT3 technology with very fast turn-on enable the use of a single gate driver or dual gate drivers. This allows easy re-design from full silicon or full SiC based inverters to a fusion inverter. Generally, Infineon’s holistic expertise in SiC MOSFET and silicon IGBT technology, power module packaging, gate drivers as well as sensors enables premium products with cost savings at system level. One example is the integration of Swoboda or XENSIV™ Hall sensors in the HybridPACK Drive package for more precise and efficient motor control.
Infineon will showcase the new HybridPACK Drive G2 Fusion at electronica 2024 in Munich from November 12 to 15 (hall C3, booth 502).

In battery-powered applications such as motor drives and switched-mode power supplies (SMPS), the power supply architecture often requires that a module can be disconnected from the main supply rail when a fault occurs in that module. To achieve this functionality, it is common to use high-side disconnect switches (e.g. MOSFETs) to prevent a load short circuit from affecting the battery.
Infineon Technologies AG introduced the EiceDRIVER™ 1EDL8011, a high-side gate driver designed to protect battery-powered applications such as cordless power tools, robotics, e-bikes, and vacuum cleaners in the event of a fault.
The device provides fast turn-on and turn-off of high-side N-channel MOSFETs with its high gate current capabilities. It consists of an integrated charge pump with an external capacitor to provide strong start-up. The internal charge pump provides the MOSFET gate voltage when the operating input voltage is low. The gate driver IC manages inrush current and provides fault protection. Undervoltage Lockout (UVLO) protection at input voltage prevents the device from operating under hazardous conditions. The driver is available in a DSO-8 package, making it ideal for space-constrained designs. It includes overcurrent protection (OCP), adjustable current setting threshold, time delay and a safe start-up mechanism with flexible blanking during MOSFET turn-on transitions.
The 1EDL8011 has a wide operating voltage range of 8 V to 125 V and a high gate sinking current of up to 1 A, allowing for efficient switching. Additionally, the product has an extremely low off-mode quiescent current of 1 µA, helping to minimize power consumption in sleep mode. The device also includes a V DS sense feature that is used to trigger an overcurrent shutdown by monitoring the drain-to-source voltage of the disconnect MOSFET.
Infineon will be showcasing a demo featuring the 1EDL8011 at its global technology forum OktoberTech™ 2024 in Silicon Valley on 17 October. The 1EDL8011 is available now. Further information can be found at www.infineon.com/1edl8011.
