TVS (Transient Voltage Suppression) diodes are utilized to protect electronic circuitry against damage caused by electrical surge. The TVS410SM series is a popular device in this category which offers superior protection against voltage spikes. It is shock and EMI tolerant and offers fast response time during transient conditions. This article aims to discuss the application field and working principle of the TVS410SM.

The TVS410SM is a bidirectional device designed for use in a wide range of applications including automotive, consumer electronics, and industrial equipment. It is available in a variety of packages to meet the needs of different applications. The device is rated for a peak pulse power of 410W and has a breakdown voltage of 38.85V, making it effective for protecting low voltage applications from surge damage.

The working principle of the TVS410SM is based on avalanche breakdown. When the surge voltage exceeds the maximum rated voltage of the device, the diode will conduct current and absorb the high-voltage spike. The device will then enter an “avalanche breakdown”, which allows the current to rise sharply at a controlled rate. This protects the device and ultimately the rest of the circuit from overheating and damage caused by the surge voltage.

The TVS410SM is designed to be highly tolerant to both shock and electromagnetic interference (EMI). It can withstand peak voltages of up to 60V and is able to absorb transient energy up to 10 times its rated power. In terms of thermal performance, it exhibits a low thermal resistance and power dissipation. This makes it ideal for use in high-power applications where protection is needed from both high- and low-level voltage surges.

The TVS410SM also features a fast response time of less than 0.5ns, making it effective for protecting against overvoltage conditions. Its low capacitance allows for fast response to sudden voltage conditions, and its internal circuit design minimizes the impact of transient events. This can help to reduce the risk of system failures due to overvoltage events.

Overall, the TVS410SM is a versatile, economical, and reliable protection device that can be used in a wide range of applications. It provides effective protection against overvoltage conditions and is designed to handle both transient and EMI events. Its fast response time, low capacitance, and low resistance make it highly suitable for high-power applications.
