SMCJ22A Description

Short technical summary and product information.

The SMCJ22A is a unidirectional TVS diode from Littelfuse Inc., part of the SMCJ series. It offers 1500W peak pulse power capability at 10/1000µs waveform, making it suitable for protecting sensitive electronic equipment from voltage transients induced by lightning and other transient events.

 

Key electrical specifications include a reverse standoff voltage of 22V, breakdown voltage range of 24.4V to 26.9V, and a clamping voltage of 35.5V at 42.3A peak pulse current. The device features excellent clamping capability, low incremental surge resistance, and a fast response time typically less than 1.0ps.

 

Designed for surface mount applications, the SMCJ22A is housed in a DO-214AB (SMC) package with a low profile and built-in strain relief. It supports a wide operating temperature range of -55°C to 150°C. Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
