The U series, available on request for applications up to 40 KHz, offers a much lower forward voltage drop to optimize conduction losses.
The Vishay Semiconductors Ultrafast diodes released today are offered with a wide range of rated currents from 2 A to 150 A. The high blocking voltage capability of the devices allows designers to provide additional safety margins and increase power density in end products. Equivalent packaged devices are available on request.
To maximize efficiency, the diodes are offered with a wide range of forward voltage vs. reverse recovery time ratios. The devices feature typical reverse recovery times down to 28 ns at +25 °C (di/dt = 200 A/µs) and forward voltage down to 1.38 V typical. For a more robust and cost-effective design, the diodes offer a maximum operating junction temperature of +175 °C.
