BZD27C16P-E3-08 Application Field and Working Principle

Introduction

BZD27C16P-E3-08 is a device from the family of diodes, in particular it is a Zener single type. It has an on state voltage of 2.4V and an off state voltage of 8V. This device also features better reliability and high stability.

Application Field

BZD27C16P-E3-08 is designed for general purpose applications, and is commonly used in power supply, charge and energy management, power conditioning, communications, automotive, industrial and consumer electronics, and automotive lighting. In particular, BZD27C16P-E3-08 can be used as voltage clamping device and regulation device to protect against spikes of high voltage which may damage other components connected to the circuit.

Working Principle

The working principle of BZD27C16P-E3-08 is based on the PN junction. It consists of two P-type semiconductor materials that have been joined together, creating a depletion region. When a voltage is applied to the PN junction, electrons from the N-type semiconductor are attracted to the P-type semiconductor and create a current through the device. The Zener voltage is determined by a depletion layer and threshold voltage. When the applied voltage exceeds the Zener voltage, the electrons come out of the junction and flow through the device. This flow is often referred to as breakdown current. The resulting voltage drop across the diode is the Zener voltage. The current that flows during breakdown is relatively small compared to the normal forward current, so its characteristics are usually ignored when using BZD27C16P-E3-08 as a voltage clamp. In addition, BZD27C16P-E3-08 also has reverse current flow characteristics. During normal operation, the reverse current flow is small, but when the applied voltage exceeds the Zener voltage, the device will pass a large current.

Conclusion

BZD27C16P-E3-08 is a Zener single type diode which is suitable for general purpose applications. It has a Zener voltage of 8V, with a breakdown current sufficient to clamp high voltage spikes. It has high reliability, stability and reverse current flow characteristics, making it suitable for applications in power supply, charge and energy management, power conditioning, communications, automotive, industrial, consumer electronics and automotive lighting.
