SMM4F28A-TR Description

Short technical summary and product information.

The SMM4F28A-TR is a unidirectional Transient Voltage Suppression (TVS) diode from STMicroelectronics, designed for general purpose protection against voltage transients. It features a peak pulse power dissipation of 400W (8/20µs waveform) and a clamping voltage of 59V at 39A peak pulse current. The device operates over a junction temperature range of -55°C to 175°C.

 

This TVS diode is housed in a compact DO-216AA surface mount package, suitable for automated assembly. It is RoHS3 compliant and has a Moisture Sensitivity Level of 1 (unlimited floor life). The unidirectional configuration makes it ideal for protecting single polarity lines in a variety of electronic circuits.
