Product details

In a continuous-conduction-mode PFC or a 100 kHz flyback, that recovery charge directly sets the turn-off loss in the companion MOSFET and the snubber dissipation. The 50 ns figure is the maximum at rated conditions — actual recovery softness depends on the forward current and di/dt, but this part gives the designer a known recovery window to size the RC snubber around.

Package and mounting — D2PAK land pattern notes

The D2PAK footprint is standard — three leads plus a tab that carries the cathode.

For BOM lines that need a fast-recovery 500 V / 5 A surface-mount diode, this part is a stable choice without an imminent replacement risk.

Frequently asked questions

Can BYC5B-600,118 be used as a replacement for BYC5B-600,112?

Both parts share the same 500 V / 5 A die and D2PAK package. The suffix change (118 vs 112) typically reflects a different packing quantity or reel size rather than a functional difference. Confirm the lead form and tape dimensions with your distributor before substituting.
