V385LA20AP Circuit Protection

TVS - Varistors, MOVs are widely used in various electronic applications and facilities. The V385LA20AP is among the most used components in this category. This component is designed to provide a high level of protection to circuits from transient overvoltage, and to enable circuits to function optimally without changes in their operating parameters.

V385LA20AP Application Field

The V385LA20AP is a 20V unidirectional Transient Voltage Suppressor (TVS) designed for use in automotive electronics, industrial and consumer applications. It is specifically designed for overvoltage protection of in-vehicle engine control modules, audio/video and power supplies. It is suitable for a wide range of EMI/RFI applications where protection from Transient Over Voltage is required. The device can withstand up to 85V of transient voltage, and is capable of providing protection up to 25A of surge current. It is also capable of withstanding up to 5kV of ESD.

V385LA20AP Working Principle

The V385LA20AP is designed to clamp dangerous voltage levels and protect components from the detrimental effects of excessive voltage. It is this clamping mechanism that makes the V385LA20AP effective at protecting electronic components from a wide variety of transient overvoltage situations. When a transient voltage appears at the input of the V385LA20AP, a voltage is generated across the device that is much lower than that of the input voltage. This lower voltage then passes through the device and is transferred to the output.

The V385LA20AP combines a metal oxide varistor (MOV) with a Zener diode. The MOV acts as a passive clamping element and helps reduce the voltage that is transferred from the input to the output. The Zener diode helps to ensure that the voltage is clamped to the limit of the device’s breakdown voltage. When an overvoltage situation occurs, the V385LA20AP acts to divert current away from sensitive components, effectively protecting them from damage.

Conclusion

The V385LA20AP is ideal for a wide range of applications that require a reliable source of protection from transient overvoltage. Its combination of a MOV and a Zener diode enables it to effectively clamp potentially dangerous voltages, ensuring that sensitive components remain undamaged. This makes the V385LA20AP an essential component in many electronic applications.
