SA150A Description

Short technical summary and product information.

The SA150A is a unidirectional transient voltage suppressor diode from On Semiconductor, part of the SA series rated for 500W peak pulse power dissipation on a 10/1000μs waveform. It offers a reverse stand-off voltage of 150V and a clamping voltage of 243V at the peak pulse current of 2.1A. The device features a fast response time of less than 1.0 ps from 0V to breakdown voltage, making it suitable for protecting sensitive electronics from voltage transients. The SA150A is packaged in a DO-204AC (DO-15) axial leaded package for through-hole mounting. It is designed for general-purpose applications and operates over a junction temperature range of -55°C to 175°C. The device is RoHS3 compliant (unverified) and has a moisture sensitivity level of 1.
