1PMT5946CE3/TR7

Diodes - Zener - Single

The 1PMT5946CE3/TR7 diode is a single Zener diode, which is generally used for stabilization and protection against voltage or current surges. It is made with a highly reliable polymer PN junction and better ESD protection to ensure reliable operation in a wide variety of harsh environments.

Application Fields

The 1PMT5946CE3/TR7 is widely used as a DC voltage regulator or protector, with a wide working range of -65°C to +150°C. It is especially suitable for applications in automotive, industrial, telecommunications, and consumer electronics, in order to ensure the stable operation of the equipment. Its main applications include surge protection, static clamp, clipping, voltage reference, overvoltage protection, and transient suppression.

Working Principle

Zener diode connection is relatively simple; a single diode can be inserted between the source voltage and ground and it allows the current to flow in one direction. When the voltage of the source exceeds a certain value (known as the Zener breakdown voltage, or “knee”), all of the current flows through the diode, causing a constant voltage drop across it.

The rule of thumb is that the Zener diode current should not exceed the device’s maximum power rating; this is to ensure that the device won’t overheat and fail. Additionally, the load current must be greater than the Zener diode current in order to take advantage of its regulated output.
