Diodes - Zener - Single

The BZT52C20-G RHG is a single Zener diode. It is a semiconductor device which provides a specific voltage regulation and protection against overvoltage. This diode can operate in both Zener and Avalanche modes. In Zener mode, the diode regulates a higher applied voltage to a fixed and low Zener voltage. In Avalanche mode, the diode will clamp a voltage and limit the current, protecting both the diode and the device being protected.

The BZT52C20-G RHG has a reverse breakdown voltage of 20 Volts +/- 5%. It has a power dissipation of 500 mW, a do-34 case, and a surge pulse current of 1 peak amp. It is available in a range of operating temperature, from -55ºC to 150ºC.

Application field

This type of diode has a wide range of applications, although it is primarily used in differential feedback circuits. It can be used in power supplies, linear regulators, and other similar applications that require a constant and stable voltage output. It can also be used as a protection circuit or as a current limiting device due to its high stability characteristics. The diode is suitable for high voltage applications, such as power transformers, fly-back regulators, and voltage regulators.

Working principle

The BZT52C20-G RHG is designed to provide a stable voltage output by means of controlling the reverse current. It works by allowing a constant, reversed current from the cathode to the anode until it reaches a certain breakdown voltage, known as the Zener voltage. This voltage is determined by the characteristics of the diode. The diode prevents reverse current from exceeding the Zener voltage, maintaining a regulated voltage.

In Zener mode, the diode allows a regulated current in the reverse direction. This regulated current acts as a gatekeeper, preventing excessive voltage from being passed to the device being protected. In the event of a sudden current surge, the diode will limit the flow of current, preventing damage to the device.

In Avalanche mode, the diode acts similarly, by limiting the flow of current and protecting the device. The diode can also be used as a protection circuit, providing additional protection from current surges.

The BZT52C20-G RHG can be used in both Zener and Avalanche modes, depending on its application. As a Zener diode, it provides a dependable, stable voltage output. In Avalanche mode, it provides protection from sudden current surges, preventing damage to the device being protected.
