Micro Commercial Components (MCC) has introduced the MURZ3065P-BP and MURZ6065P-BP, a new family of 650V superfast recovery rectifiers targeting high-frequency power conversion applications across industrial, renewable energy and automotive systems.
The new rectifiers combine a 650V reverse voltage rating with average forward current ratings of 30A for the MURZ3065P-BP and 60A for the MURZ6065P-BP. Both devices are housed in rugged TO-247AD packages designed to provide effective thermal dissipation and straightforward heatsink mounting in high-power systems.
A key feature of the series is its fast reverse recovery performance. The devices offer reverse recovery times of 95ns and 105ns, helping reduce switching losses as converter operating frequencies increase. Soft recovery characteristics and low reverse recovery charge also help limit electromagnetic interference and improve switching behavior.
Typical forward voltage is 1.29V and 1.28V, respectively, helping reduce conduction losses and improve overall conversion efficiency. The devices also feature near-zero temperature coefficient characteristics, supporting stable forward-voltage and switching behavior across a broad operating temperature range and simplifying thermal management.
For applications exposed to transient overloads, the rectifiers provide surge current capability of up to 220A and 400A, depending on the device. MCC also uses planar-structure die technology to support device reliability and manufacturing consistency.
The combination of high current capability, fast and soft recovery, low forward voltage and robust thermal characteristics makes the MURZ Series suitable for power factor correction circuits, uninterruptible power supplies, industrial power supplies, EV charging equipment, welding systems and inverter applications.
The launch expands MCC’s high-voltage rectifier portfolio as power electronics designers seek lower switching and conduction losses in increasingly high-frequency and power-dense converter architectures.
