Product details

100 V, 10 A dual Schottky in a TO-262 through-hole package

Forward voltage is 850 mV maximum at 10 A, and the junction can operate up to 175°C. The part comes in a TO-262-3 (I²PAK) through-hole package, shipped in tube form. It is designed for high-frequency rectification and OR-ing applications in power supplies where Schottky's low forward drop and fast recovery (≤500 ns) reduce switching losses.

For existing BOM lines, procurement must go through independent distribution channels.

The 100 V Vr rating gives headroom for 48 V or 60 V bus rails with derating. Each diode handles 10 A continuous, so the common-cathode pair can serve a 20 A center-tap rectifier or two independent 10 A OR-ing channels. The 850 mV Vf at 10 A is typical for a 100 V Schottky at this current density — expect higher drop at elevated junction temperatures.

Frequently asked questions
