1.5KE220-E3/73

TVS (transien voltage suppressors) diodes are essential components of an electric system and are essential for reducing voltage spikes and lightning-induced transient surges. 1.5KE220-E3/73 TVS diodes are peak power transient voltage suppressor diodes designed to provide protection of sensitive electrical components from high-energy transients. These diodes are typically used to provide over-voltage protection in consumer electronics, automotive, telecommunications, industrial, and automotive applications.

1.5KE220-E3/73 TVS diodes have a peak pulse power of 1400 watts and are designed to protect against surges from lightning, switching loads, and other transient events. The device has a breakdown voltage of 220V and is available in a variety of packages including axial packages, radial leaded packages, and surface-mount devices. The device utilizes an internal Zener diode and an NPN transistor to provide protection from transient over-voltage spikes. The device is available with a variety of different electrical ratings and is capable of withstanding transient surges up to 600V peak.

The 1.5KE220-E3/73 TVS diode utilizes the Avalanche Breakdown Injection structure which is a combination of Zener and Shunt breakdown. This structure gives it the ability to respond to very fast transients and can withstand a higher range of surge voltages. A Zener diode clamps the voltage to the breakdown voltage and a shunt transistor is used to clamp the current flowing through the diode. The device is also capable of withstanding transient over-currents up to 30A.

The working principle of the 1.5KE220-E3/73 TVS Diode is based on breakdown injection. During an over-voltage event, an avalanche breakdown voltage is induced in the diode, causing the voltage across the device to rise. The internal Zener diode triggers the NPN transistor, which allows current to flow into the device and clamp the induced voltage. This clamping force helps reduce the peak of the transient over-voltage and reduce its duration. The internal transistor is designed to protect the device from static overloads and electrical over-speed conditions.

The 1.5KE220-E3/73 TVS diode is specifically designed for protection of sensitive electrical components from over-voltage or transient surges and can be used in consumer electronics, automotive, telecommunications, industrial, and automotive applications. The device is designed to protect the components from transient surges up to 600V peak and can withstand a peak power of 1400 watts. The device also features an ultra-high surge capability and is capable of operating in wide temperature ranges. It is available in a variety of packages and is easy to install and maintain.
