Introduction

TVS - Diodes, also known as Transient Voltage Suppressors (TVSs), are widely used components that help to protect circuits from overvoltage scenarios. The TVS diode is an electronic component, built into a discrete package that protects a circuit from excessive voltage transients. These transient voltages can occur due to electrostatic discharge, lightning, or any other caused by inductive strikes. The TVS diode is designed to clamp voltage to a safe level, thus protecting the attached circuit and components from transient voltage.

TPSMA8.2HE3/61T Application Field and Working Principle

The TPSMA8.2HE3/61T is a 600W peak pulse power unidirectional TVS diode specifically designed to protect sensitive electronic components. It is packaged in an 8-lead SMD (surface mount device) with an MSOP (mini-small outline package) and is designed for reliable and low-capacitance performance. It is especially useful for very power-sensitive applications where signal integrity is paramount. The device is designed using low-capacitance silicon diode technology to be used as a protective device in an integrated circuit (IC) or other type of circuit.The TPSMA8.2HE3/61T offers protection from transient voltage spikes, ESD (Electrostatic Discharge), EFT (electrical fast transients), and other overvoltage events. It is designed with high transient energies (>10A for 8/20 μs pulse) to provide higher power and superior performance over other TVS diodes. It also has low reverse leakage current and capacitance at high breakdown voltages. The unit is RoHS compliant and features an 8-lead MSOP package with a maximum peak pulse power rating of 600W.The working principle of the TPSMA8.2HE3/61T is simple. When it is exposed to a transient surge, it begins to conduct current through its junction, allowing a safe level of total peak power to be dissipated from the circuit. The diode will absorb the transient and protect the IC from the surge. The diode’s low reverse leakage current and capacitance safely dissipate the transients allowing the connected component to operate normally.

Conclusion

The TPSMA8.2HE3/61T TVS diode is an effective, high-performance component that helps protect circuits from transient voltage spikes. It is designed with low-capacitance silicon diode technology, and features high transient energy and peak power ratings, as well as a low reverse leakage current and capacitance. The device is RoHS compliant, making it suitable for a wide range of applications. It is an effective solution for protecting sensitive electronic components and circuits from overvoltage events.
