The CDZFHT2RA9.1B is a single Zener diode, capable of regulating and providing a source of constant voltage. It is designed to divert or clamp excess voltage in electronic circuits, allowing them to operate with consistent levels of electrical current. As a popular controllable device, the CDZFHT2RA9.1B offers a wide range of applications in numerous fields.

Key Applications and Properties

The CDZFHT2RA9.1B is commonly used in logic circuits, power conditioning systems and analog communications. It has a variety of applications such as providing reverse bias protection, stepped-up voltage generation and voltage buildup stabilization in AC/DC and other circuits. Its key properties also make it well-suited for static or dynamic clamping of output transistors, as well as for applications such as voltage protection, voltage motors and voltage regulators.

Operation and Specifications

The CDZFHT2RA9.1B is a low power device with a maximum power dissipation of 200 mW. It is designed to reach a maximum operating temperature of 150 °C and comes with a maximum DC reverse voltage between 5.5 and 12.5 V. Once running, it will regulate excess voltage to 9.1 VDC. It includes a D15 package with a hermetically sealed ceramic case, and its junction temperature is controlled by its internal thermal shutdown circuit. This feature allows the device to be used in most applications without causing any damage or limiting performance.

Working Principle

The CDZFHT2RA9.1B operates based on the principle of Zener breakdown. This happens when a reverse bias voltage within a diode increase beyond a certain level, which allows electrons within the material to become free and cross the junction. This creates a region of free charge carriers in the depletion region, where electrons and holes create an avalanche of electrical current. The breakdown voltage of the device is the minimum voltage required to achieve Zener breakdown. Once Zener breakdown occurs, the current passes through the diode and the voltage levels will remain constant. As such, it is well-suited for operations such as clamping or voltage regulation.

Conclusion

The CDZFHT2RA9.1B is a popular single Zener diode device, designed to regulate excess voltage in electronic circuits. It has numerous applications across many fields and is known for its low power dissipation and high reliability. The device works based on the principle of Zener breakdown, where a reverse bias voltage causes an avalanche of electrical current to flow, and the voltage will remain constant. The CDZFHT2RA9.1B is an optimal choice for many electrical designs, providing a low-cost and energy efficient solution for voltage regulation.
