Product details

Fast recovery diode for 600 V boost and clamp circuits

The BYR29-600,127 is a standard fast recovery diode from WECN Semiconductor, rated for 600 V reverse voltage and 8 A average rectified current. Its 75 ns reverse recovery time places it in the fast-recovery class, suitable for continuous-conduction-mode boost PFC stages, flyback snubbers, and output rectification in switched-mode power supplies where reverse-recovery charge drives switching losses.

75 ns trr — sizing the snubber and the switching loss

The 75 ns reverse recovery time is the key switching parameter. Forward voltage is 1.5 V maximum at 8 A.

Through-hole TO-220AC — mounting and thermal interface

The TO-220-2 (TO-220AC) package has two leads and a metal tab. The tab is electrically connected to the cathode.

For a production line that needs a 600 V, 8 A fast recovery diode in a TO-220 package, this part is a current-production option with no imminent obsolescence risk.

Frequently asked questions

What is the reverse recovery time of BYR29-600,127?

The reverse recovery time (trr) is 75 ns, measured under standard test conditions. This qualifies it as a fast recovery diode suitable for switching frequencies up to about 100 kHz in hard-switched topologies.
