1N5937E3/TR13

Diodes - Zener - Single

1N5937E3/TR13 is a single Zener diode. It is most suitable for voltage regulation and surge suppression applications. The diode acts as a back-to-back pair when two devices are bolted together.

Application Field

1N5937E3/TR13 Zener diodes are used for fixing the voltage for voltage regulator and surge suppressor. It is designed for usage in automotive power circuits, rectifier assemblies and traffic signal installation. Since this device is designed to stand off high reverse breakdown voltages, it can operate in transients caused by automotive systems.

Working Principle

The working principle of 1N5937E3/TR13 is based on the reverse breakdown voltage of the diode. Zener diodes are designed to have a reverse breakdown voltage (Vz) above their reverse leakage current (Iz). This allows them to exhibit a breakdown event when the voltage across them exceeds Vz. The breakdown event causes large current to flow and consequently fixes the voltage across the diode at Vz, thereby providing voltage regulation.
