Diodes - Zener - Single

The 1PMT5947B/TR13 is a type of diode developed by Diodes Inc., specifically for in-circuit protection applications where high voltage is involved. It is a unidirectional bipolar Zenner with a tightly controlled breakdown voltage of 13V, making it suitable for use in 12V systems.

Application Field: It is commonly used for over-voltage crowbar protection, battery protection, and in automotive automotive applications. The 1PMT5947B/TR13 is designed with a very low power consumption of only 700mW, making it a good choice for automotive applications or other high current applications where trying to keep power consumption low is important.

Working Principle: The 1PMT5947B/TR13 works by responding to an over-voltage situation and “triggering” a circuit breaker that will disconnect the power. The diode is connected between the system’s power supply and the circuit breaker. When the voltage on the power supply reaches the breakdown voltage of the diode, the diode will trigger the circuit breaker and the power will be shut off. This prevents over-voltage from damaging the system.

The 1PMT5947B/TR13 is a popular choice for applications where low power consumption and high voltage protection is desired. It is a reliable, well-tested option for a variety of applications.
