SMBJ45CA Description

Short technical summary and product information.

The SMBJ45CA is a 600W bidirectional transient voltage suppression (TVS) diode from the Littelfuse SMBJ series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It provides a clamping voltage of 72.7V and can handle a peak pulse current of 8.3A under 10/1000μs waveform. The device is surface mounted in a compact DO-214AA (SMB) package, suitable for automated assembly. With a fast response time of less than 1.0ps from 0V to VBR min, it offers excellent ESD protection up to 30kV air and contact per IEC 61000-4-2. The operating temperature range spans -65°C to 150°C, making it reliable in harsh environments. It is commonly used for protecting I/O interfaces, VCC bus, and circuits in telecom, computer, industrial, and consumer applications.
