TVS - Diodes are constantly advancing in terms of technology, and the 1.5KE20CA-E3/73 is an excellent example of this. This device is designed to protect against transients that can cause problems in circuits, such as overvoltage and overcurrent. It is robust and reliable, providing protection for all types of circuits, whether for commercial, industrial, or automotive applications.

The 1.5KE20CA-E3/73 is a silicon-based transient voltage suppressor (TVS) diode designed to act as a bidirectional protection device in high-voltage circuits. It can protect against voltage transients including Electrostatic Discharge (ESD) and other types of electrical noise.

The device has a breakdown voltage of 20V and a clamping voltage of 28V, with a peak pulse power rating of 1500W. This is more than enough to handle most surges, and it can withstand repetitive surges of up to 200A, making it suitable for all types of circuits.

The 1.5KE20CA-E3/73 is a unidirectional device, meaning it can only protect against ESD and other noise from one direction. This makes it suitable for use in circuits where protection from both directions is not needed, as well as in applications where a single ESD pulse needs to be suppressed before it can reach sensitive components. The device can be used in diode OR’ing for reverse supply blocking, as well as in clamps, inverters, and other circuits where overvoltage protection is needed. It is also suitable for any automotive, industrial, or consumer application.

The working principle of the 1.5KE20CA-E3/73 is relatively simple. When a voltage above the 20V breakdown voltage is applied to the device, it will begin to conduct and limit the voltage to the 28V clamping voltage. This then prevents further transients from reaching downstream components and protect them from damage. The diode is also bidirectional, which means that it can provide protection from both polarities of a voltage transient.

In conclusion, the 1.5KE20CA-E3/73 is an excellent choice for a variety of applications. It offers robust protection from both single and repetitive voltage transients, and its unidirectional design makes it suitable for use with sensitive components. Furthermore, its breakdown voltage of 20V and clamping voltage of 28V make it suitable for use in a wide range of circuits, from automotive to consumer and industrial applications.
