Product details

120 V, 10 A dual Schottky — the core ratings

Forward voltage is 920 mV at 10 A, with a reverse leakage of 10 µA at the 120 V mark. The switching speed falls under the fast-recovery class — ≤ 500 ns at currents above 200 mA — which suits it for output rectification in switch-mode power supplies and freewheeling diode roles in motor drives or DC-DC converters.

For a production BOM that calls this exact diode, the path is last-time-buy inventory through independent distribution.

Package and thermal context

Housed in a TO-220-3 through-hole package with narrow leads. Maximum junction temperature is 175 °C.
