Introduction

A TVS, or transient voltage suppressor, is a special type of diode used to protect sensitive electronic devices from voltage surges or spikes in a circuit. It is often used in conjunction with a diode rectifier and other components to protect devices from short-circuit conditions. It is one of the most common types of electronic protection devices and is among the most reliable and effective protection devices available.

1SMC16A TR13 application field and working principle

The 1SMC16A TR13 is a transient voltage suppressor diode designed for high surge protection. It is small, lightweight, and low-cost, and provides good common-mode surge protection. The 1SMC16A TR13 is a single piece device, including a P-channel MOSFET, NPN Transistor, and Schottky diode, providing bidirectional protection. This device\'s working principle is to divert the transient energy away from sensitive components. When a voltage spike occurs, the device will become forward-biased and current will flow through the diode, bypassing the sensitive component. The P-channel MOSFET provides additional protection by allowing most of the transient current to be diverted away from the system. Since this device is bidirectional, it will also be able to provide reverse-bias protection in the event of a negative voltage spike.
