UFB200FA40 Description

Short technical summary and product information.

The UFB200FA40 is a dual diode module featuring two independent ultrafast soft recovery diodes in a single SOT-227 package. It is rated for a maximum DC reverse voltage of 400V and an average rectified current of 100A per leg (200A total per module). The typical forward voltage is 1.0V at 100A and 150°C, with a maximum of 1.24V at 25°C. The fast recovery characteristic provides typical reverse recovery times of 60ns under low-current conditions and 93ns at rated current.

 

The module is designed for output rectification, freewheeling, and clamping operations in high voltage power supplies, HF welders, motor control, and inverters. The electrically isolated base plate allows for common heatsinks and compact assemblies. The SOT-227 (miniBLOC) package is chassis mountable and features a mounting torque of 1.3 N·m. The junction-to-case thermal resistance is 0.5 °C/W per leg, and the case-to-heatsink thermal resistance is 0.05 °C/W. The operating junction temperature range is -55°C to 150°C.
