SMBJ33CA Description

Short technical summary and product information.

The SMBJ33CA is a bidirectional transient voltage suppressor (TVS) diode from Semtech, designed to protect sensitive electronics from voltage transients. It is part of the SMBJ series and offers a peak pulse power dissipation of 600W (10/1000μs). The device has a clamping voltage of 53.3V at a peak pulse current of 11.3A. It features a fast response time of less than 5 ps for bidirectional operation. The SMBJ33CA is suitable for telecom applications and provides surge protection per IEC 61000-4-5. It is housed in a surface mount DO-214AA (SMB) package, with an operating temperature range of -55°C to 175°C (junction). The device is RoHS3 compliant and has an MSL of Level 1. It is not intended for power line protection.
