SMCJ30A-E3/9AT Description

Short technical summary and product information.

The SMCJ30A-E3/9AT is a unidirectional TVS diode from Vishay Dale, designed to protect sensitive electronics from voltage transients. It features a working voltage of 30V, a breakdown voltage of 33.3V at 1mA, and a clamping voltage of 48.4V at 31A peak pulse current. The device can handle 1500W of peak pulse power under a 10/1000μs waveform.

 

This TVS diode is housed in a DO-214AB (SMC) surface mount package and supports an operating temperature range of -55°C to 150°C. It offers a fast response time of less than 1ps from 0V to breakdown voltage, making it suitable for high-speed transient protection. The part is unidirectional and rated for a peak forward surge current of 200A.

 

Typical applications include power supply protection, data line protection, and general-purpose circuit protection in industrial and consumer electronics. The surface mount package enables automated assembly and compact PCB designs.
