SMAJ28CA Description

Short technical summary and product information.

The SMAJ28CA is a bidirectional transient voltage suppressor (TVS) diode from Littelfuse, designed for general purpose surge protection. It features a reverse standoff voltage of 28V and a maximum clamping voltage of 45.4V. The device can handle peak pulse currents up to 8.8A (10/1000µs waveform) and dissipates 400W of peak pulse power (1ms pulse).

 

The SMAJ28CA is housed in a DO-214AC (SMA) surface mount package, suitable for automated assembly. It operates over a junction temperature range of -65°C to 150°C. The component is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited). It does not provide power line protection and is intended for use in electronic circuits requiring protection against voltage transients.
