Low-forward-voltage 1,200 V diodes target high-power rectification

A new family of 1,200 V rectifier diodes is available in ThinDPAK, D2PAK-D, and TO-247BD packages from Taiwan Semiconductor. The devices are offered with current ratings of 15 A, 30 A, and 60 A. Each diode series supports a maximum forward-voltage rating of 1.3 V and maintains low reverse leakage below 10 µA at 25 °C. The junction temperature rating is 175 °C.

All six models are designed for single-configuration rectification. Two versions, PLAD15QH and PLDS30QH, meet the AEC-Q automotive qualification. The remaining four models maintain similar electrical characteristics and mechanical formats without automotive qualification.

These diodes are intended for high-voltage power conversion and rectification. Representative uses include three-phase AC/DC conversion, computing power systems, AI-related power architectures, EV charging equipment, on-board battery charging, Vienna rectifier topologies, totem-pole and other bridgeless designs, inverters, UPS systems, and high-power general rectification.
