Introduction

The PLVA2656A,215 is one of the most popular Zener arrays for electronic applications. This Zener array consists of 10 Zener diodes, arranged in series-parallel configuration, with 215 thresholds ranging from 6.3 volts to 210 volts. The PLVA2656A,215 is used in many applications and is especially suited to reverse voltage protection, constant voltage regulation, and as a reference voltage source.

Application Fields

The PLVA2656A,215 is used in a wide range of applications, especially in the protection of sensitive electronics and in voltage regulation. The PLVA2656A,215 can be used as a robust reverse-voltage protection device to protect sensitive circuits and components from voltage spikes or surges. The range of Zener breakdown voltages covered by the device enable it to be used for a wide variety of over-voltage protection applications. As the PLVA2656A,215 is also highly accurate and stable, it is an ideal choice when used as a reference voltage source. By precisely controlling the reverse bias voltage applied to the device, highly precise voltage references can be obtained. The PLVA2656A,215 is therefore well suited to exact voltage regulation.

Working Principle

The PLVA2656A,215 works by making use of 10 Zener diodes arranged in series-parallel configuration. The arrangement of the circuit allows for a precise control of the breakdown voltage of each Zener diode. The Zener diodes are connected in series, meaning that each voltage drop is added to the total voltage providing precise control of the Zener voltage. The Zener diodes are also connected in parallel, allowing for current carrying capacity to be increased and improving the overall performance of the device. The PLVA2656A,215 is designed to operate in three distinct modes. When reverse bias voltage is applied to the device, the Zener diodes start to conduct and the breakdown voltage of each diode is established. When the voltage drops below the threshold of the diode, the diode will stop conducting and the device will enter its low current, Zener breakdown mode. This mode allows for current to pass through the device at extremely low levels and is useful for power conservation. Finally, when the reverse bias voltage is removed, the device will enter its high current, breakdown-overvoltage mode and the diodes will stop conducting.

Conclusion

The PLVA2656A,215 is an incredibly versatile Zener array for electronic applications. It consists of 10 Zener diodes arranged in series-parallel configuration with a wide range of breakdown voltages, making it an ideal choice for reverse voltage protection, constant voltage regulation, and as a reference voltage source. The circuit works by making use of the Breaking Voltage of the Zener diode and allowing for precise control of the device\'s breakdown voltage. The PLVA2656A,215 can be used in many different applications and is widely used for its accuracy and stability.
