SMCJ120A Description

Short technical summary and product information.

The SMCJ120A is a unidirectional transient voltage suppression (TVS) diode from Littelfuse, designed to protect sensitive electronic circuits from voltage transients. It features a reverse standoff voltage of 120V and a breakdown voltage of 133V (min). The device clamps transient overvoltages at 193V (max) while handling a peak pulse current of 7.8A (10/1000µs waveform).

 

With a peak pulse power rating of 1500W, the SMCJ120A is suitable for general-purpose protection in telecom, computer, industrial, and consumer applications. It offers fast response time (typically less than 1.0ps) and low incremental surge resistance.

 

The device is housed in a DO-214AB (SMC) surface-mount package, with an operating temperature range of -55°C to 150°C. It is halogen free and RoHS compliant, with matte tin lead-free plating. The SMCJ120A is part of the SMCJ series and is available in tape and reel packaging.
