It is designed for the output stage of switch-mode power supplies, freewheeling diodes in DC-DC converters, and reverse-polarity protection circuits where low forward voltage drop and fast switching reduce losses. The 100 V reverse voltage rating and 3 A average current suit point-of-load converters and auxiliary supply rails. ## Junction temperature and package — thermal design factors Rated junction temperature spans -40°C to 175°C. The SOD-128 flat package keeps the cathode tab area small. Forward voltage is 760 mV maximum at 3 A and 25°C — typical conduction loss at full current is about 2.3 W, which the package must sink through the board. At elevated junction temperature the forward voltage drops slightly, but reverse leakage rises, so the thermal budget should be checked at the worst-case operating point. ## Active lifecycle and compliance — no supply-chain surprises ROHS3 compliant per the compliance listing, so it fits unrestricted EU and global BOMs without exemption tracking. The base product number STPS3 covers a family of 3 A Schottky diodes; the H100AF suffix specifies the 100 V rating and the SOD-128 flat package.","metaTitle":"STPS3H100AF Schottky Diode, 100 V 3 A, SOD-128 Flat, Active","metaDescription":"STPS3H100AF Schottky rectifier: 100 V reverse, 3 A forward, fast recovery ≤500 ns.
