1,200-V diodes offer low loss, high efficiency

Taiwan Semiconductor launches a new series of automotive-grade, low-loss diodes in three popular industry-standard packages. They provide an automotive-level performance upgrade in existing designs and low-power dissipation required for higher-power rectification applications.

The 1,200-V PLA/PLD series, with ratings of 15 A, 30 A or 60 A, all feature low forward voltage (1.3 Vf max), low reverse leakage (<10 µA at 25°C), and high junction temperature (175°C Tj max). They are available in three packages—ThinDPAK, D2PAK-D, and TO-247BD—for design flexibility.

These 1,200-V diodes provide easy drop-in replacements using an industry-standard pinout to improve efficiency in existing designs, according to the company. They can be used in a variety of applications such as three-phase AC/DC converters, server and computing power (including AI power) systems, EV charging stations, on-board battery chargers, Vienna rectifiers, totem pole and bridgeless topologies, inverters and UPS systems, and general-purpose rectification in high-power systems.

The new PLA/PLD series is offered in six models manufactured to automotive-quality standards. Two of the models, the PLAD15QH (ThinDPAK) and PLDS30QH (D2PAK-D), are fully AEC-Q qualified for automotive applications. The other four models include the PLAD15Q (ThinDPAK), PLDS30Q (D2PAK-D), PLAH30Q (TO-247BD), and PLAH60Q (TO-247BD).

The PLA/PLD series are sampling now. They are in-stock at DigiKey and Mouser. Production lead times is 8-14 weeks ARO. Design resources include datasheets, spice models, Foster and Cauer thermal models, and CAD files (symbol, footprint, and 3D model).
