1.5KE130A

TVS – Diodes are a semiconductor device available in a wide variety of packages and configurations. They are commonly used in a variety of applications to protect circuits from overvoltage and overcurrent conditions. The 1.5KE130A is a unidirectional TVS diode designed to protect circuits from transient voltage overvoltage events.

1.5KE130A Application Field:

The 1.5KE130A is specifically designed for function when exposed to ESD, EFT, and lightning strikes. It is suitable for primary protection from voltage and current transients in consumer electronics, such as set-top boxes, laptop computers, servers, networking equipment, telecommunication centers, and medical devices.

1.5KE130A Working Principle:

A 1.5KE130A simply works by providing a path for the voltage/current surge to be diverted away from the protected circuitry. When the transient voltage exceeds the device’s breakdown level, the diode is triggered causing it to enter a high-conductance state. This is known as the avalanche breakdown voltage (VRWM). Once in this state, the device quickly diverts the current away from the protected component, thus protecting it from damage.

The voltage overshoot is limited by the clamping action of the 1.5KE130A. This is dependent on the junction capacitance and the stage of avalanche breakdown. The 1.5KE130A has a very low capacitance, which makes it ideal for clamping high frequency transients. Additionally, its fast response time further enhances its protection capability and helps reduce potential damage.

In conclusion, the 1.5KE130A is a TVS diode designed to protect circuits from transient voltage overvoltage events. It is ideal for high-frequency energy transients, ESD, EFT, and lightning strikes, and is suitable for primary protection of set-top boxes, laptops, servers, networking equipment, telecommunication centers, and medical devices.
