SMAJ12CAHE3/5A Description

Short technical summary and product information.

The SMAJ12CAHE3/5A is a bidirectional TVS diode from Vishay's TRANSZORB family. It is designed to protect sensitive electronics from voltage transients induced by inductive load switching and lightning. Key electrical specifications include a reverse standoff voltage of 12 V, a clamping voltage of 19.9 V, and a peak pulse current of 20.1 A under a 10/1000 μs waveform. The device offers 400 W minimum peak pulse power and a maximum power dissipation of 3.3 W on an infinite heatsink at 50°C. Operating temperature range is -55°C to 150°C (junction temperature).

 

This TVS diode is AEC-Q101 qualified, making it suitable for automotive applications. It is packaged in a DO-214AC (SMA) surface-mount case, which is low profile and ideal for automated placement. The device is RoHS compliant and meets MSL level 1 per J-STD-020. It features a glass passivated chip junction, fast response time, and low incremental surge resistance. The bidirectional polarity is indicated by the CA suffix in the part number.
