Introduction

Diodes – Zener – Single is a type of diode with a special property: it will have a reverse breakdown effect, allowing a small amount of current to flow backwards in the device across a triangular potential barrier. This special effect allows these diodes to be used in applications such as voltage regulation and reference, current limiting and more. Specifically, PZU6.2BA,115 is a 6.2 Volt Zener diode with a power rating of 500 mW.

Application Field

PZU6.2BA,115 is well-suited for applications where a 6.2 Volt Zener diode is required. It is most frequently used for the purposes of voltage regulation and reference, current limiting, or in applications needing electrical surge protection. They are also frequently used in reverse voltage protection circuits, as well as in transient suppression circuits. It can also be used in voltage regulator circuits, wherein the diode will create summative and subtractive combinations of input voltages in order to produce a desired regulated output voltage.

Typical Operating Conditions

In order to ensure optimal performance, PZU6.2BA,115’s operating conditions should be kept within an allowable range. The maximum forward voltage is 1V at 1 mA, and the maximum reverse current should be no greater than 5mA. The maximum power effect is when the Zener voltage is less than 5% below the rated Zener voltage. The maximum resistive load is determined by the power dissipation capability.

Working Principle

Unlike the traditional diode, a Zenar diode is specifically designed to essentially short-circuit the current when a given voltage is exceeded. This is accomplished via an inward-directed depletion region that occurs when a Zener voltage is applied across the diode. This is accomplished by the majority carriers, typically electrons, trying to cross the PN junction and flow in the opposite direction. To explain further, when under normal conditions, the majority carriers, be they electrons or holes, will migrate across the PN junction, they will be electrostatically opposed by the minority carriers. However, when a reverse polarity voltage is applied across the junction, the minority carriers will be pushed back, creating a depletion layer, the reverse current then becomes limited to the user-specified Zener voltage value. The stability at the Zener voltage is due to the tunneling effect of majority carriers through the depletion layer, allowing for stable current at the specified Zener voltage.

Conclusion

In conclusion, PZU6.2BA,115 is an ideal choice for any application requiring a 6.2 Volt Zener diode for its many uses, such as voltage regulation and reference, current limiting, and surge protection. Its reversible current limiting properties make it a suitable choice for many different types of circuits and applications. Its special working principle allows it to regulate the current and maintain it at a specified Zener voltage.
