SMCJ120A Description

Short technical summary and product information.

The Bourns SMCJ120A is a unidirectional TVS (Transient Voltage Suppression) diode designed to protect sensitive electronic circuits from voltage transients. It features a reverse standoff voltage of 120V and a maximum clamping voltage of 193V at a peak pulse current of 7.9A. With a peak pulse power dissipation of 1500W (10/1000µs waveform), this diode offers robust protection for general purpose applications.

 

The device is available in a surface mount DO-214AB (SMC) package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. The SMCJ120A is a unidirectional component, with one protection channel, and is not intended for power line protection.

 

Typical applications include voltage transient suppression in telecom, computer, industrial, and consumer electronics. Its compact size and high power rating make it an ideal choice for board-level protection where space is limited and reliability is critical.
