Transient Voltage Suppressors (TVS) diodes exemplify a variety of unidirectional and bidirectional overvoltage protection components used for protecting electrical scores in many products containing sensitive electronics. The 3KASMC30HE3/57T is a bidirectional TVS (Transient Voltage Suppressor) diode and belongs to the class of TVS diodes.

Typical applications of the 3KASMC30HE3/57T are in various products such as communications server systems, routers, base stations, data storage systems, power supplies, and embedded systems. It is also suitable for the protection of industrial systems against overvoltage transients such as ESD shocks, electrical fast transients, and surges induced through connections in the system.

The 3KASMC30HE3/57T is designed to protect both AC and DC power supply lines. It provides protection against highly energetic transients such as electrostatic discharges, lightning induced surges, and other high power transients. The protection level of the 3KASMC30HE3/57T is 30 A (8/20 µs) and allows for an operating voltage up to 5.75 V. It has a low clamping voltage of 9.1 V and a low leakage current of 4 µA. The device also features an operating temperature range of -55°C to +125°C and can operate up to an altitude of 25 km.

The working principle of the 3KASMC30HE3/57T is rooted in its ability to behave like a current source. When the device is exposed to an overvoltage, it behaves like a current source and limits the current through the device. On the other hand, when the device is exposed to an undervoltage, it behaves like a resistor and diverts the current around the device. This ensures that the device does not fail when exposed to excessive or inconsistent high and low voltages.

Among its many features, the 3KASMC30HE3/57T also includes protection against electrostatic discharge (ESD), electrical fast transients (EFT) and lightning induced surges (LIS). The device allows for easy and cost-effective integration into various products and provides a multi-level protection up to 30 A (10/1000µs). It also features fast response times to protect against peak currents, minimizing impulse response times.

The 3KASMC30HE3/57T is a robust and reliable bidirectional TVS diode that provides superior protection to sensitive systems and devices against overvoltage transients. It offers intensive protection while maintaining low clamping voltage and low leakage current rates. This makes it an ideal solution for a wide range of applications including communications server systems, routers, base stations, data storage systems, power supplies, embedded systems, and industrial systems.
