A TVS - Diodes, SMB8J13CHE3/5B is a general purpose surface mount bidirectional Transient Voltage Suppressor. The device was designed to protect vulnerable electronic components from destructive voltage transients due to lightning and other causes. It features 2-watt power dissipation capability and a wide operating temperature range of -55C to 175C.

The SMB8J13CHE3/5B forms an integral part of many electronic systems. It comes with a working voltage rating ranging from 5V to 170V and a peak pulse power of 7kW. With a low standoff voltage of 8.5V, the device is especially suitable for line voltage applications such as mobile phones, electronic devices, on-board vehicle electronics and other applications.

The SMB8J13CHE3/5B is designed to work in different operating modes such as avalanche diode, Zener, SCR and Combination Mode. In combination mode, it can simultaneously function as a voltage body diode and a transistor. In its Zener mode, the device helps regulate output voltage levels while preventing transient overvoltage spikes.

In its Avalanche Diode mode, the device is used to detect voltage transients in the circuit and then engage its clamping and absorption mechanism. This mechanism helps dissipate the energy from the transient to protect the circuit and its components from any damaging effects. The avalanche diode mode also helps the device detect potential destructive voltage transients.

In the SCR mode, the device can be used to regulate heart rate currents between 200mA to higher levels. In addition, the device acts as a bidirectional voltage regulator by controlling reverse currents. By controlling current in both directions, the device is effective in suppressing surges caused by electrostatic discharge, lightning storms and more.

The SMB8J13CHE3/5B device features a high surge current, low capacitance, high breakdown voltage and a fast response time.
