Diodes - Zener - Single - 1PMT4132C/TR13 application field and working principle

The 1PMT4132C/TR13 is a type of zener diode based on a two terminal semiconductor device. The diode is made using a single P-type and N-type substrate. The main function of this diode is to allow a regulated current to flow in one direction while blocking it in the other. The zener breakdown voltage of this diode is 13V.

There are a wide variety of applications where this diode can be used. It can be used in power supplies, as a stabilizing component for voltage regulation, as a surge protector for AC/DC voltage, for voltage clamping and for over-voltage protection. It can also be used in rectifiers, switching applications, circuit protection and more.

The working principle of the 1PMT4132C/TR13 is based on the fact that when the voltage is increased to above its zener breakdown voltage (13V), an avalanche breakdown occurs. This causes current flow through the diode, which increases exponentially with greater voltage drops.

Avalanche breakdown in the diode creates a large number of charge carriers on the N-type side which in turn creates a strong electric field at the junction. This electric field accelerates the electrons to the positive side, creating holes which allow the current to flow in both directions. The voltage at the junction stays constant, while the current is regulated.

The diode has a power rating of 500mW, a package size of 2.9 x 5.4mm, a voltage rating of 13V and a maximum reverse leakage current of 20µA. The 1PMT4132C/TR13 is designed to operate in temperatures from -55°C to +175°C. The diode has a highly reliable design, offers superior performance and long-term operational stability.

In conclusion, the 1PMT4132C/TR13 is a type of zener diode used in a wide range of applications. It has a zener breakdown voltage of 13V, a power rating of 500mW and operates in temperatures from -55°C to +175°C. The diode works by allowing a regulated current to flow in one direction while blocking it in the other. It is highly reliable and offers superior performance.
