30 A, 100 V Schottky in a fully isolated TO-220FP
The STMicroelectronics STPS30SM100SFP is a 30 A, 100 V Schottky rectifier in the TO-220 Full Pack (TO-220FPAB) package. The fast recovery characteristic (≤500 ns, >200 mA) suits it for high-frequency rectification, freewheeling diodes in switching converters, and output rectification in flyback and forward topologies where Schottky's low forward drop and fast switching reduce losses.
This means STMicroelectronics has ended production; no further factory orders are accepted. Any new design-in should target a current-production alternative. The base product number is STPS30, and the STPS30SM100 series includes several active siblings in the same TO-220FP package — a parametric review against your specific voltage, current, and Vf requirements will identify the closest drop-in candidate.
Key electrical ratings for the power budget
The 100 V DC reverse voltage (Vr max) and 30 A average rectified current (Io) define the operating envelope for output rectification.
Package and mounting — TO-220 Full Pack specifics
The TO-220-3 Full Pack (supplier device package TO-220FPAB) is a through-hole, three-lead package with a fully molded backside. Unlike a standard TO-220, the metal tab is fully encapsulated, so the device can be bolted directly to a chassis or heatsink without an isolation pad. The mounting hole is sized for an M3 screw. This package is common in off-line power supplies and motor drives where the heatsink is at earth potential.
