203DMQ100 Description

Short technical summary and product information.

The 203DMQ100 is a high-current Schottky rectifier module designed for demanding power conversion and industrial applications. It integrates two 100A Schottky diodes in a series (center-tap) configuration, delivering a total average forward current of 200A per device. The peak repetitive reverse voltage rating is 100V.

 

Key electrical parameters include a low typical forward voltage drop of 0.86V at 100A and 25°C and a maximum reverse current of 3mA at 100V and 25°C. The device is capable of handling high surge currents, with a non-repetitive surge current rating of 2520A per leg. Junction capacitance is typically 2670pF, and the operating junction temperature range spans -55°C to +175°C.

 

The 203DMQ100 is housed in a PRM4 isolated baseplate module designed for chassis mount installation. The module's thermal performance is supported with a junction-to-case thermal resistance of 0.30 °C/W per leg and 0.15 °C/W per package. This module is ideal for use in high-frequency switching power supplies, plating power supplies, free-wheeling diodes, UPS systems, and welding equipment.
