TVS (transient voltage suppressors) diodes, also known as spark gaps, are solid-state devices used to protect sensitive electrical equipment from electrical damage. They work by restraining overvoltage transients, such as lightning strikes, electrostatic discharge, and other forms of surge current, from damaging critical circuits. The VTVS36ASMF-HM3-08 is a TVS diode used in a variety of applications, including electronics, medical devices, and automotive applications. In this article, we discuss the application field and working principle of this diode.

Application Field

The VTVS36ASMF-HM3-08 is a low capacitance, surface mount transient voltage suppressor diode. It is designed to provide effective transient protection for a variety of electronic systems. The diode offers a high peak power capability of 200W. It is suitable for use in circuits with differential and common mode voltage levels over the full range of −6 to +65V DC.

The VTVS36ASMF-HM3-08 can be used in a wide variety of applications, including telecommunications equipment, medical equipment, industrial controls, automotive electronics, and consumer electronics. It is particularly well suited to applications requiring a high peak power capability. For example, it can be used to protect automotive antitheft controllers, power management circuits, and other circuits requiring a high degree of transient protection.

Working Principle

The VTVS36ASMF-HM3-08 is an active-shunt diode. Under normal operating conditions, the diode applies a small voltage drop across its anode and cathode terminals. This provides a low impedance path through which excess current can flow in the event of a transient. When an overvoltage transient occurs, the diode quickly switches to a high impedance state, allowing the excess current to flow through the diode and be safely dissipated. The diode then automatically switches back to its low impedance state once the transient has passed.

The VTVS36ASMF-HM3-08 is designed to provide effective transient protection through its ability to absorb large transients quickly. The diode has an internal clamp which limits the applied voltage to the circuit. It also has a low clamping voltage and low leakage current, which allows for a high peak power capability while minimizing the possibility of damage to the protected circuit.

The VTVS36ASMF-HM3-08 is designed to provide superior electrical protection in a wide range of applications. It is robust, reliable, and cost-effective, making it an ideal solution for transient protection requirements. Its ability to quickly absorb large transients makes it well suited for use in high-power applications, and its low clamping voltage and low leakage current limit the possibility of damage to the protected circuit.
