SMDJ51A Description

Short technical summary and product information.

The SMDJ51A is a 3000W peak pulse power transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients. It is a unidirectional device with a reverse standoff voltage of 51V and a clamping voltage of 82.4V at a peak pulse current of 36.4A (10/1000µs waveform). The device offers a fast response time of less than 1.0 ps from 0V to breakdown voltage.

 

This TVS diode is suitable for general purpose applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. It features a peak forward surge current capability of 300A (8.3ms) and a maximum forward voltage of 3.5V at 100A for unidirectional parts.

 

The SMDJ51A is housed in a surface mount DO-214AB (SMC) package with matte tin lead-free plated terminals. It operates over a junction temperature range of -65°C to 150°C and has a power dissipation of 6.5W at lead temperature 50°C. The device is RoHS3 compliant, REACH unaffected, and halogen free.
