SMBJ90A Description

Short technical summary and product information.

The SMBJ90A from Littelfuse is a surface mount unidirectional TVS diode rated at 600W peak pulse power (10/1000μs waveform). It has a reverse standoff voltage of 90V and a maximum clamping voltage of 146V at a peak pulse current of 4.1A. The device is designed for general purpose protection against voltage transients induced by lightning and other transient events in telecom, computer, industrial, and consumer electronics applications.

 

Key electrical characteristics include a fast response time of less than 1ps from 0V to breakdown voltage, low incremental surge resistance, and typical reverse leakage current below 1μA. The diode is packaged in a DO-214AA (SMB) surface mount package, offering optimized board space usage. Operating temperature ranges from -65°C to 150°C.

 

The SMBJ90A is RoHS3 compliant, halogen free, and MSL Level 1. It is UL recognized to ANSI/UL 497B for data communication and fire-alarm circuit protection. The component features matte tin lead-free plating and meets JEDEC solder reflow requirements at 260°C.
