1PMT4622C/TR13

Diodes - Zener - Single

The 1PMT4622C/TR13 is a 600mW SOD-123 Package Zener Diode from NXP Semiconductors.

Application Field

The main application for the 1PMT4622C/TR13 is the protection of circuits from voltage transients. Zener Diodes are diodes used for voltage regulation, as the voltage across it remains constant for a large dynamic range of input. Having a Zener Diode in a circuit design means you can protect the circuit from input transients and keep the output voltage at a desired level.

Working Principle

A Zener Diode is like a normal diode, but with a reversed breakdown voltage. With normal forward biased diodes, it will allow current to flow in one direction, but the reverse biased diodes will block it. With the Zener Diode, a current will flow even in the reverse direction when it reaches its specified breakdown voltage. This Zener breakdown voltage is usually around 5-6V for a particular diode.

The 1PMT4622C/TR13\'s breakdown voltage is 5.6V, which means that as long as there\'s a voltage differential of 5.6V across the diode, it will allow the current to flow in the reverse direction. This is useful for protection purposes, as it will let the surplus current pass through and reduce the voltage levels to the appropriate values.

In order for Zener Diodes to be used in circuits, it must first be connected to the appropriate voltage level. After that, the current flowing through the Zener Diode must be limited so as to not overwhelm the diode. This can be done by putting a resistor in series with the diode, so that the current through the diode falls within its specified range.

Conclusion

The 1PMT4622C/TR13 Zener Diode is a great choice for circuit protection needs. Its reasonable 5.6V breakdown voltage and 600mW power dissipation rating make it an ideal choice for a wide range of applications. Also, by choosing a resistor in series with the diode, we can easily limit the current through the diode and ensure that our circuit design is protected from input transients.
