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.
