Taiwan Semiconductor announced a new 1,200 V PLA/PLD diode series aimed at automotive and high-reliability power systems. The devices, rated at 15 A, 30 A, and 60 A, combine a low forward voltage (1.3 Vf max), low reverse leakage (<10 µA at 25 °C), and a high junction temperature rating (Tj max 175 °C) to improve efficiency and thermal headroom in demanding environments.
The portfolio is offered in ThinDPAK, D2PAK-D, and TO-247BD packages, enabling straightforward drop-in replacement in existing layouts. Two models, PLAD15QH and PLDS30QH, are fully AEC-Q qualified for automotive use. All six devices are manufactured to stringent automotive-quality standards.
Target applications span three-phase AC/DC converters, server and computing power systems including AI power shelves, EV charging stations and on-board chargers, Vienna rectifiers, totem-pole and bridgeless PFC topologies, inverters and UPS systems, and general-purpose high-power rectification.
By pairing low conduction loss with controlled leakage and high temperature capability, the PLA/PLD diodes are positioned to boost efficiency, reduce thermal dissipation, and enhance reliability across both new and retrofit power designs.
