SMBJ11CA Description

Short technical summary and product information.

The SMBJ11CA is a 600W bidirectional TVS diode from Littelfuse's SMBJ series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Key electrical specifications include an 11V reverse standoff voltage (VRWM), 18.2V clamping voltage at 33A peak pulse current, and 600W peak pulse power capability under a 10/1000μs waveform. The device features a fast response time of typically less than 1.0ps from 0V to breakdown voltage.

The SMBJ11CA comes in a surface-mount DO-214AA (SMB) package with matte tin lead-free plating. It is RoHS compliant, halogen free, and meets MSL level 1. Operating temperature range is -65°C to 150°C (junction). Typical applications include general-purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
