Working principle of 1PMT5922BT3

The operating principle of the 1PMT5922BT3 single zener diode is to use the forward bias to introduce current into the diode, which in turn generate heat. What makes this diode extraordinary is that its heat output can be adjusted to make it perform at certain voltage or current level. This process is known as the Zener breakdown.

When applying a forward bias to the 1PMT5922BT3 diode, electrons from the n-type material in the junction can cross into the p-type region. This will depend on the built-in bias of the diode. When the current exceeds the zener voltage of the diode, a condition known as zener breakdown will take place. In this condition, the number of electrons entering the p-region increases, resulting in an avalanche effect.
