TVS or Transient Voltage Suppressors are diodes used to protect electronic circuits from Electrostatic Discharge (ESD) events, electrical over-stresses or power surges that may damage sensitive components. SM8S28HE3/2D is a two bidirectional TVS diode package with low leakage current and high clamping capability. It is particularly suitable for protection from power surges in consumer electronics, automotive and telecommunication applications.

This TVS diode has a working voltage of 28V and a peak pulse power rating of 600W at a 10/1000μs pulse waveform. The operating temperature range is from -55°C up to 175°C. Its low leakage current (15μA typical) and low breakdown voltage of 8.9V at 25°C make it an ideal choice for protecting electronic circuits.

The working principle of the SM8S28HE3/2D TVS diode is based on the breakdown mechanism of a PN junction. When the junction voltage exceeds a certain level, based on the type of the diode, then a reverse breakdown occurs resulting in a large current flow. This phenomenon is known as a breakdown voltage, and it is used to protect circuits from both ESD and power surges. The breakdown voltage of the SM8S28HE3/2D is 8.9V. This diode has a fast response time and provides provide reliable protection against ESD levels up to ±25kV (air).

The SM8S28HE3/2D TVS diode can be used in a variety of applications, including consumer electronics, telecom and automotive. In consumer electronics, the diode can be used to protect circuits from ESD and power surges. In telecom, the diode can be used for protection from electrical over-stresses or power surges in sensitive circuits. In automotive, the diode can be used for surge protection from load dump, vehicle transients and electrical over-stresses.

The SM8S28HE3/2D diode offers reliable ESD protection for a wide range of applications. It features low leakage current, wide working temperature range and high peak power ratings making it an ideal choice for protecting circuits from power surges and ESD events.
