SMCJ350A Description

Short technical summary and product information.

The SMCJ350A is a unidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 350V and a maximum clamping voltage of 567V, with a peak pulse power dissipation of 1500W at 10/1000µs waveform. The device can handle a peak pulse current of 2.6A.

 

Housed in a surface mount DO-214AB (SMC) package, the SMCJ350A is suitable for automated assembly. It operates over a temperature range of -55°C to 150°C. The diode is intended for general purpose applications such as I/O interfaces, VCC bus protection, and transient suppression in telecom, computer, and industrial electronics.

 

The SMCJ series offers fast response time and low incremental surge resistance. This part is unidirectional, providing protection for one channel. Compliance with RoHS and halogen-free requirements is claimed for the series (unverified for this specific part).
