A diodes-zener-single is a two-terminal device that, when connected in reverse bias, allows current flow in the opposite direction to the normal current flow, with a potential applied backwards across the junction. The GDZT2R8.2 is a double-breaker and thermal-exchange diode. It is designed to provide low forward voltage/low leakage current and improved thermal exchange that allows higher power ratings in a compact space.

GDZT2R8.2 Application and Working Principle

The GDZT2R8.2 is applied in circuits to regulate voltages and to protect sensitive electronic equipment and circuits from system overvoltage. It includes two diode devices in one package and features a unique double-breaker structure. Its thermal exchange module provides low voltage/leakage current and improved thermal exchange, allowing higher power ratings in a small space.

When the reverse voltage reaches the rated zener voltage (VZ), the GDZT2R8.2 starts to conduct at a specified current (IZ). This will cause the current to flow through the diode, reducing the available reverse voltage. The voltage between VZ and the maximum reverse voltage (VRMAX) is termed the Zener breakdown region.

The GDZT2R8.2’s thermal exchange module optimizes the thermal management, improving the performance of the device and allowing it to be used in applications with high power consumption. The thermal exchange module also helps reduce the temperature of the junction, improving the device’s reliability.

Additionally, the double-breaker structure of the GDZT2R8.2 helps protect the system from overvoltage due to lightning or power supply problems. The double-breaker feature is based on the principle of activation energy, where once the forward voltage reaches a certain level the current across the junction increases exponentially. This fast current increase clamps the reverse voltage, protecting the system from further damage.

Conclusion

The GDZT2R8.2 is a double-breaker and thermal-exchange diode device that can provide power ratings of up to 3A in a compact space. It is typically used to regulate voltages and protect sensitive circuits and equipment from overvoltage. The device’s thermal exchange module helps reduce the junction temperature, increasing its reliability. Additionally, the double-breaker feature helps protect the system from further damage due to lightnings and power supply problems.
