Working Principle

1N5374C/TR12 works on the principle of voltage-dependent breakdown or Zener breakdown. When a voltage is applied across a forward-biased diode, it allows the current to flow through it. As the voltage is increased further, the electric field across the depletion layer of the diode increases to such an extent that the electrons and holes in the depletion layer make the semiconductor breakdown. This process is known as Zener breakdown and is the mode of operation of the 1N5374C/TR12. As the applied voltage increases beyond a certain level, known as the Zener voltage, the current through the diode increases drastically, due to the increase in its reverse-conducting region. This Zener voltage is set by the manufacturer which is usually between 5 volts and 200 volts.

The 1N5374C/TR12 provides linear regulation, which makes it ideal for high-voltage regulation applications. It can be easily used as a voltage reference in applications such as switching power supply, filter circuit, voltage amplifier and voltage regulator. It also provides protection against transient voltage spikes or over-current, which is beneficial in applications such as battery level monitoring and circuit protection.
