25 ns reverse recovery — what it buys the snubber
The BYG22D-M3/TR is a Vishay avalanche-rated fast-recovery diode in a DO-214AC (SMA) surface-mount package.
200 V blocking, 2 A forward — derating reality
Rated 200 V DC reverse voltage (Vr) and 2 A average rectified current (Io). Reverse leakage is 1 µA at 200 V, 25 °C junction. Leakage doubles roughly every 10 °C rise; at 125 °C junction it climbs into the tens of microamps, still manageable for most off-line supplies but worth budgeting in high-temperature hold-up capacitor discharge paths.
Listed as Active in production status. ROHS3 compliant.
