TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are components designed to protect delicate electronic circuits from electrical surges caused by electrostatic discharge, lightning strikes, and other sudden and dangerous power spikes. TVS diodes have been used to protect circuit boards from damage caused by ESD and power surges for decades. They are particularly useful in protecting sensitive data systems from unexpected power or ESD events.The PGSMAJ78CAHM2G is a unidirectional TVS diode that features a standoff voltage of 68V and a maximum peak pulse power of 2.0KW. The PGSMAJ78CAHM2G is used in applications where fast and reliable overvoltage protection is required. It also features a low leakage current of 1.2μA at 25°C and a peak surge current of 500A.The PGSMAJ78CAHM2G\'s metal-oxide-varistor (MOV) provides fast and reliable overvoltage protection to sensitive electronic devices. The MOV\'s ability to absorb overvoltage spikes quickly and efficiently enables the PGSMAJ78CAHM2G to protect electronic equipment from power surges. As a result, it is often used to protect data systems, computer servers, and communication equipment from damage due to overvoltages. The PGSMAJ78CAHM2G is also suitable for use in automotive applications because of its robust design. Its high surge current rating allows the PGSMAJ78CAHM2G to protect vehicles from electrical surges caused by engine clearance or spark events. For safety reasons, it is recommended to place the TVS diode as close to the protected device as possible in order to reduce the chances of the surge damaging the device.The PGSMAJ78CAHM2G is designed to perform in temperatures ranging from -55°C to 150°C, so it can be used in high temperature environments where thermal management is an issue. The PGSMAJ78CAHM2G is also designed with tight operating voltage and power capability to ensure reliable protection of sensitive electronics.When the PGSMAJ78CAHM2G senses an overvoltage, it quickly absorbs the surge energy, while maintaining a low temperature coefficient of capacitance. The diode will then dissipate the excess energy as heat and return the protected voltage to its normal level. With its fast-acting overvoltage protection and low leakage current, the PGSMAJ78CAHM2G is the ideal choice for protecting against power surges in many applications.The PGSMAJ78CAHM2G is a reliable and cost-effective solution for protecting sensitive electronics from damaging electrical surges. Its rugged construction, fast-acting overvoltage protection, and tight operating voltages make it an ideal choice for applications that require reliable and cost-efficient protection.
