Transient Voltage Suppressors (TVS) are specially designed diodes made especially to cope with transient overvoltage conditions. The TPSMD60A (SMC) is one of the most advanced TVS diode, designed to protect system components from transient overvoltages. It is designed to handle energy dissipations up to 1.0 Watt and handle an avalanche energy of up to 400mJ. In this article, we will discuss the application field and working principle of the TPSMD60A.

Application Field of TPSMD60A

The TPSMD60A is primarily for use in sensitive equipment exposed to transient overvoltage conditions, such as automotive units. It is commonly used to protect automotive components, including electronic control units (ECUs) and power train fault nodes, from static overcharges, ESD pulses, inductive transients, and conductive surges. It is also used for signal line protection and can withstand up to 50A peak pulses and 400A peak avalanche pulses.

Working Principle of TPSMD60A

The TPSMD60A utilizes a patented Clamping Circuit (CC) technology. This technology works by way of a reverse-biased clamping diode which is designed to handle high-capacity pulses and quickly avalanche when needed, clamping the peak voltage down to a safe level. This diode is triggered by a high-voltage, high-density avalanche region which quickly suppresses negative surges. When the surge is over, the diode’s reverse-bias current reverses and restrains the total power consumption. In addition, the TPSMD60A uses an avalanche suppressing zener structure to improve clamping levels.

The TPSMD60A offers superior protection against static overcharges, ESD pulses, inductive transients, and conductive surges. It can handle up to 1500mV clamping voltage, clamping drop of 400mV, and pass less than 25µA leakage current. It also has a low response time of less than 2.5ns. The TPSMD60A is also suitable for reflow soldering and because of its wide temperature range can also handle a wide variety of automation processes.

Conclusion

The TPSMD60A is a high-performance TVS diode that is designed to protect sensitive equipment from transient overvoltage conditions. It utilizes advanced Clamping Circuit (CC) technology and is capable of handling up to 1.0 Watt of energy and 400mJ of avalanche energy. It is widely used in automotive, telecommunications, and other industries which require superior protection. It can handle up to 1500mV clamping voltage, a clamping drop of 400mV, and pass less than 25µA leakage current. Its response time is also extremely fast at less than 2.5ns.
