TVS diodes, or transient voltage suppressor diodes, are one of the most important components of an electronic circuit. They protect circuits from potential damage caused by transient voltage spikes. The PGSMAJ85CAHM2G is a popular choice for many applications, offering excellent protection and reliability. This article will discuss the application field and working principle of the PGSMAJ85CAHM2G.

Application Field

The PGSMAJ85CAHM2G is a unidirectional TVS diode designed for use in 12V automotive applications. It is most commonly used in airbag control modules, engine control units, and transmission control modules. The diode is also suitable for use in industrial applications, such as data line protection, power surge protection, and overvoltage protection of power supplies. Using this diode in automotive and industrial applications ensures that circuits are protected from voltage spikes, protecting against damage and even fires.

Working Principle

The PGSMAJ85CAHM2G is designed to protect sensitive electronics from transient voltage spikes. When a voltage spike exceeding the diode\'s breakdown voltage occurs, it quickly converts the excess voltage into a current that is diverted from the protected circuit, thus protecting it from damage. The diode can handle a surge current up to 17A, which is sufficient for most automotive and industrial applications. The diode also has a low leakage current and is capable of handling transient voltages up to 85V.

The PGSMAJ85CAHM2G is also designed to be robust and reliable. It is constructed using solid-state construction and is hermetically sealed with an epoxy filling, making it resistant to shock, vibration, and temperature extremes. The diode also has a low failure rate and is designed to last for years with minimal maintenance.

Conclusion

The PGSMAJ85CAHM2G is an excellent choice for many applications, offering excellent protection and reliable performance. It is designed for use in 12V automotive and industrial applications, and is capable of handling transient voltages up to 85V with a surge current up to 17A. The diode is also robust and reliable, with a low leakage current and a low failure rate. It is an excellent choice for circuit protection against voltage spikes.
