Diodes - Zener - Single: 1PMT5919B/TR7

The 1PMT5919B/TR7 is a Zener diode from NXP semiconductors, with a maximum power dissipation of 775 mW @Ta = 25°C and a peak reverse voltage of 9.1 V. It is a single component component, which can be used in various applications. The 1PMT5919B/TR7 is often used in voltage regulation, voltage measurement and transient protection circuits.

Application Field

The 1PMT5919B/TR7 is often used for voltage regulation, as it is capable of being reverse biased, creating a protection circuit from you value being over voltaged. This makes it ideal for clamping, or providing a form of overvoltage protection. Additionally, it is also used in voltage measuring circuits, as its voltage regulator can be easily calculated to provide accurate measurements. Furthermore, it can also be used in transient protection circuits to provide protection from extremely high-voltage shocks.

Working Principle

The working principle of the 1PMT5919B/TR7 is quite simple. When forward biased, the Zener diode acts as a regular diode and allows current to flow. However, when reverse biased, it turns into a voltage regulator, with a very precise voltage. This is caused by the decrease of the total capacitance at the junction of the Zener diode. As a result, the precise voltage resulting from the decrease in capacitance can then be used for various applications.

Conclusion

In conclusion, the 1PMT5919B/TR7 Zener diode is ideal for use in voltage regulation, voltage measurement, and transient protection circuits. Its working principle is based on reducing capacitance at the diode junction in order to create a precise voltage. Ultimately, its precise voltage regulation, as well as its ability to handle high voltages and currents, make it a suitable choice for use in a variety of different applications.
