SMBJ51CA-E3/52 Description

Short technical summary and product information.

The Vishay Dale SMBJ51CA-E3/52 is a surface-mount Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronics from voltage transients. It features a low profile DO-214AA (SMB) package, making it suitable for automated placement.

 

This bidirectional TVS diode provides 600W of peak pulse power dissipation with a 10/1000 μs waveform. Its working peak reverse voltage ranges from 5V to 188V, with a breakdown voltage range of 6.4V to 231V. The clamping voltage is rated at 82.4V at 1mA test current. It operates reliably across a wide temperature range of -55°C to 150°C.

 

Key features include excellent clamping capability and very fast response times. The device is ideal for protecting ICs, MOSFETs, and signal lines in consumer, computer, industrial, and telecommunication applications against transients induced by inductive load switching and lighting.

 

Mechanical data indicates the case is SMB (DO-214AA) with matte tin plated leads. The molding compound meets UL 94 V-0 flammability rating. It is designed for surface mount applications.
