STPR120A Description

Short technical summary and product information.

The STPR120A is a fast recovery rectifier diode designed for high efficiency switching applications. It features a low forward voltage drop of 0.94V at 1A and 25°C, and 0.74V at 150°C, which reduces conduction losses. The reverse recovery time is typically 25ns (max 35ns), enabling high frequency operation. The device is rated for a repetitive peak reverse voltage of 200V and an average forward current of 1A. It can handle surge currents up to 30A. The diode is housed in a surface mount SMA (DO-214AC) package, suitable for automated assembly. Typical applications include switched mode power supplies, DC/DC converters, and freewheeling diodes.
