SMAJ85CA Description

Short technical summary and product information.

The Bourns SMAJ85CA is a bidirectional transient voltage suppressor diode designed to protect sensitive electronics from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.

 

Key electrical specifications include a working peak reverse voltage of 85V, maximum clamping voltage of 137V at peak pulse current, and a peak pulse power rating of 400W (10/1000µs waveform). The device offers fast response time of less than 5 picoseconds from 0V to minimum breakdown voltage, making it suitable for high-speed signal lines.

 

The SMAJ85CA is housed in a DO-214AC (SMA) surface mount package and is rated for operation over -55°C to +150°C temperature range. It complies with IEC 61000-4-2 ESD protection Level 4 and is UL recognized under file E153537.
