Working Principle

The PGSMAJ85CAHR3G is designed to provide maximum protection against over-voltage transients in high voltage applications. When a transient voltage is applied to the device, the diode conducts current through the integrated zener diode and clamping diode. This current passes through the integrated zener diode, which clamps the voltage at the device’s rated voltage, and is then absorbed by the clamping diode. The absorbed current is dissipated as heat to protect the circuitry from the transient.

Conclusion

The PGSMAJ85CAHR3G is an ideal TVS diode for Automotive and High Voltage DC applications. It features a wide operating voltage range, a high maximum clamping voltage, low reverse leakage current, and excellent surge capability. Additionally, the PGSMAJ85CAHR3G offers optimal protection against transient over-voltage conditions, providing a reliable and robust solution for automotive and high voltage applications.
