5.0SMDJ78A Description

Short technical summary and product information.

The 5.0SMDJ78A is a 5000W transient voltage suppression (TVS) diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 78V and a clamping voltage of 126V at a peak pulse current of 39.7A (10/1000µs waveform). The device is unidirectional with a single channel and offers fast response time of less than 1.0ps from 0V to breakdown voltage.

 

This TVS diode is suitable for telecom applications and provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2. It is housed in a surface mount DO-214AB (SMC) package with an operating temperature range of -65°C to 150°C. The device is RoHS compliant, halogen free, and has a Pb-free E3 terminal finish.

 

The 5.0SMDJ78A is part of the 5.0SMDJ series and is recognized to UL 497B as an isolated loop circuit protector. It offers low dynamic resistance and built-in strain relief for reliable performance.
