TVS (Transient Voltage Suppressor) diodes are devices that protect sensitive electronics from surges of static electricity, lightning surges, and transiently high voltage signals. They are also known as thyristors, clampers, and clamps.1.5KE20CA-Bis a general-purpose low-power unidirectional and bidirectional TVS diode with a stand-off voltage rating of 20V. It is suitable for very sensitive electronic circuits, and its working voltage is very low, which can effectively reduce surge, ESD and other overvoltage problems.The 1.5KE20CA-B TVS diode is made up of two separate components; a Zener diode for unidirectional protection and a bilateral Transient Voltage Suppressor (TVS) diode for bidirectional protection. The Zener diode provides unidirectional protection, which is effective against transients in both polarities. The TVS diode provides bidirectional protection; it also regulates the voltage at the level of the breakdown voltage of the TVS diode, instead of directly clamping the voltage at a certain level.The working principle of 1.5KE20CA-B is based on the avalanche breakdown of the junction. When a transient voltage surge exceeds the breakdown voltage of the diode, it will saturate the junction, resulting in a very low voltage drop across it. This low voltage drop protects the components connected to the 1.5KE20CA-B from being damaged by the transient surge. The TVS diodes also provide overvoltage protection in sensitive electronic circuits in order to prevent catastrophic failure.The 1.5KE20CA-B TVS diode can be used in a wide range of applications including consumer electronic, medical device, and automotive components. It is especially suitable for applications that require very quiet and low noise operation. It can also be used in industrial and military equipment to protect them from the transients that can occur during operation. It can also be used in power supplies to protect them from destructive electrical surges.In conclusion, the 1.5KE20CA-B is a low-power, versatile, and cost-effective TVS diode ideal for a wide variety of applications. Its low break down voltage provides overvoltage protection, and its bilateral protection capability prevents damage by providing regulated voltage. The 1.5KE20CA-B is an invaluable tool for the protection of sensitive electronic components from transient surges and other voltage spikes.
