Introduction

PLZ5V1B-HG3/H is specifically designed and manufactured by Vishay as a diode-zener single. A diode-zener single, which is composed of two active elements, is used for the purpose of providing a constant voltage or current through an electrical circuit. The two active elements are a diode and a zener. The diode establishes the direction of current flow, while the zener acts as a voltage regulator and can prevent current from ascending and descending.

Application Field

The PLZ5V1B-HG3/H diode-zener single is specifically RTFM-AECQ101 qualified, meaning it is specifically designed for use in automotive and industrial environments. This level of qualification is only achieved by products that have been tested to aerospace standards, allowing it to be used in demanding safety-critical applications such as those found in the automotive, aerospace, and industrial industries. The PLZ5V1B-HG3/H diode-zener single offers a wide range of application fields. It is suitable for regulating current and voltage in electric circuits, including power supplies, battery charging/discharging/protection circuits, inverter/servo motor driver circuits, control circuits, and others. Additionally, it can be used to protect circuits against surges and transients.

Working Principle

In the PLZ5V1B-HG3/H diode-zener single, the two active elements, diode and zener, work together in order to regulate the current or voltage in the circuit. The diode is the element responsible for establishing the direction of current flow – it allows current to flow in one direction only. On the other hand, the zener is the element that actually regulates the current or voltage. It prevents current from ascending and descending, thus maintaining a regulated output. When a voltage is applied to the zener, it creates a voltage drop across its terminals, meaning that current will be diverted through the zener instead of passing the load. The voltage drop that the zener creates acts as a regulating point, meaning that any rise or fall in the voltage of the circuit will be dampened by the zener, ensuring that the load receives a steady output.

Conclusion

The PLZ5V1B-HG3/H diode-zener single is a voltage regulator that is specifically designed and manufactured by Vishay for harsh conditions such as those found in the automotive, aerospace, and industrial industries. The two active elements, diode and zener, interact to regulate current or voltage in an electrical circuit, thus maintaining a regulated output. This makes the PLZ5V1B-HG3/H diode-zener single a suitable choice for multiple application fields, from power supplies to battery protection circuits.
