SMCJ28A Description

Short technical summary and product information.

The SMCJ28A is a 1500W unidirectional transient voltage suppression (TVS) diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It features a reverse standoff voltage of 28V and a maximum clamping voltage of 45.4V at a peak pulse current of 33.1A (10/1000µs waveform).

 

The device offers excellent clamping capability, low incremental surge resistance, and a fast response time of less than 1.0ps from 0V to breakdown voltage. It is rated for ESD protection up to 30kV (air and contact) per IEC 61000-4-2. The SMCJ28A is housed in a DO-214AB (SMC) surface mount package with matte tin lead-free plating, suitable for automated assembly.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The part is RoHS3 compliant, halogen free, and meets MSL level 1 per J-STD-020.
