1PMT5945C/TR13 application field and working principle

1PMT5945C/TR13 is a single Zener diode. It contains two terminals, an anode, and a cathode. It is mainly used in voltage regulation, switching, voltage stabilization and clipping circuits.

Technical parameters

1PMT5945C/TR13 has a maximum reverse voltage of 9.1V, a nominal Zener Voltage of 5.6V and a maximum Zener power of 350mW. Its maximum reverse current is 7.1mW and the maximum reverse voltage is 9.0V. It has a maximum operating temperature of +150°C and a storage temperature of -40°C to +125°C. It is in a SOT-23 package with a height of 300μm.

Working principle

Zener diodes operate on the principle of reverse breakdown of a reverse bias PN junction. The Zener diode has a threshold voltage called the Zener voltage or the breakdown voltage. When a reverse voltage is applied across the diode, the electrons in the P-region are pushed to the N-region. When this voltage reaches the breakdown voltage, the depletion layer of the PN junction breaks down and a large amount of current starts to flow through the device. This establishes a stable voltage path called the Zener voltage. The Zener diode is designed to provide a stable voltage reference even when the current through it increases.

Applications

1PMT5945C/TR13 is mainly used in voltage regulation, switching, voltage stabilization and clipping circuits. It can also be used in power control circuits, electronic flashers and monitors, as well as DC-DC converters. It can also be used in low voltage applications such as battery-operated systems. Thanks to its low price and high performance, 1PMT5945C/TR13 is an ideal choice for many applications.
