BZM55C5V6-TR

Diodes - Zener - Single

The BZM55C5V6-TR is a single Zener diode that features a reverse breakdown voltage of 5.6 volts. In other words, it will maintain a reverse voltage of up to 5.6 volts without breaking down. Zener diodes are often used in voltage regulation applications since they can protect circuits against excessive voltage.

The BZM55C5V6-TR is a three-pin, THT-package Zener diode that offers a forward current of 500mA and a reverse current of 5uA. It has been designed to offer reliable performance even in harsh environments, with a maximum working temperature of 175°C. The diode can withstand reverse voltages up to 6.4 volts. It is also isolated from the substrate for improved thermal performance.

Application Fields

The BZM55C5V6-TR is a versatile Zener diode that can be used in a variety of applications. It can be used in voltage regulation, with its reverse breakdown voltage providing protection against high voltage. It can also be used to create voltage references and bias circuits, where its low forward voltage drop makes it ideal for low power dissipation applications. Additionally, the diode is often used as a clamp, diverting current away from sensitive components.

Working Principle

When a reverse voltage is applied to the BZM55C5V6-TR, the internal electric field will increase until it reaches a breakdown voltage of 5.6 volts. This will cause the diode to become an almost perfect conductor and a reverse current will flow. This current is limited due to the diode\'s low reverse leakage current. In this state, the diode will maintain a steady voltage of 5.6 volts regardless of changes to the applied voltage.

When a forward voltage is applied to the diode, it will turn on and behave like a regular diode. Its low forward resistance and high reverse breakdown voltage make it ideal for use in low power, high voltage applications. It can be used to regulate voltage levels and provide protection against excessive voltage.

Conclusion

The BZM55C5V6-TR is an ideal choice for a variety of applications that require voltage regulation, voltage reference and bias circuits, or current clamping. Thanks to its low forward resistance and high reverse breakdown voltage, it can maintain a steady voltage of up to 5.6 volts regardless of changes to the applied voltage. Its excellent thermal performance and low reverse current leakage make it suitable for even the most demanding applications.
