Diodes, particularly Zener diodes, constitute the base technology of many electronic devices. The 1PMT5918/TR13 is a single Zener diode, offered as a single discrete diode. It is a glass-passivated surface-mount device that was originally developed as a junction-isolated Zener voltage reference.
Applications
The 1PMT5918/TR13 is typically used in applications where rapid switching is required, such as in power supplies, automotive circuits, audio power amplifiers and switching converters. This diode can also be used as an ESD protection device or in voltage regulation circuits to create a stable voltage source. It has been successfully used in low-noise, low-dropout voltage regulators, and can provide voltage stabilization in LED lighting systems.
Working Principle
A Zener diode works on the principle of avalanche breakdown. In a normal diode, the forward voltage drop is 0.7 Volts. However, when it is forward biased and the voltage exceeds a certain breakdown voltage, the electric current flows through it without large changes in the voltage. This breakdown voltage is known as the Zener voltage and needs to be set in most applications. The 1PMT5918/TR13 Zener diode has a low Zener voltage, typically between 3 and 6 volts, making it an ideal choice for low power projects.
When the diode is reverse biased, it behaves like a normal diode, allowing current to pass through it in one direction only. When the reverse voltage across the diode is increased beyond the breakdown voltage, a large surge of current will passthrough it, greatly reducing the voltage across it. This in turn prevents the voltage from rising further, providing a constant and stable output.
Conclusion
The 1PMT5918/TR13 is a single Zener diode that can efficiently and effectively provide voltage stabilization in applications where quick switching and high reliability are desired. Its low Zener voltage range makes it an ideal choice for low-power applications, and its ability to provide protection from electrostatic discharge makes it highly suitable for all types of electronic projects, including automotive applications.
