STPS3170AF Description

Short technical summary and product information.

The STPS3170AF is a Schottky rectifier diode designed for high-efficiency power conversion. It offers a maximum reverse voltage of 170V and an average rectified current of 3A. The forward voltage is typically 820mV at 3A, enabling low power dissipation. The device features fast recovery speed (≤500ns at >200mA), suitable for high-frequency switching applications. It is housed in a DO-214AC (SMA Flat Leads) surface mount package, designated as SMAflat, and operates over a junction temperature range of -40°C to 175°C. This diode is RoHS3 compliant and has an MSL of 1 (unlimited). It is commonly used in power supplies, DC-DC converters, and reverse polarity protection circuits.
