SMAJ18CAHE3/61 Description

Short technical summary and product information.

The SMAJ18CAHE3/61 is a bidirectional Zener TVS diode manufactured by Vishay Dale. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.

 

Key electrical specifications include a reverse stand-off voltage of 18 V, a minimum breakdown voltage of 20 V at 1 mA, and a maximum clamping voltage of 29.2 V at 13.7 A. The device can handle 400 W of peak pulse power dissipation with a 10/1000 μs waveform (derated to 300 W above 78 V). It also features a peak forward surge current rating of 40 A for unidirectional operation.

 

The diode is housed in a DO-214AC (SMA) surface-mount package and supports an operating junction temperature range of -55°C to +150°C. It is supplied in tape and reel packaging for automated assembly.
