Working Principle

The BZM55C9V1-TR3 is a subminiature voltage reference diode that operates on the principle of breakdown voltage regulation. The diode has a built-in zener breakdown element that regulates its output voltage. When the junction voltage exceeds a certain level, the zener element breaks down and the output voltage is clamped to a preset value. This voltage is maintained across a wide range of temperatures, current and voltage conditions. The BZM55C9V1-TR3 also has a low maximum power dissipation of 500mW.
