It is also a perfect component to be used in high power batteries and standby power supplies, as it offers protection in case of overvoltage.

CZRA4740-HF Working Principle

The CZRA4740-HF works based on the Zener effect, in which a forward-biased, light-weight junction absorbs a large amount of electrical current. The junction then continues to permit current in the reverse direction until a reverse voltage is applied, which causes the junction to break down and create a reverse current. The junction is referred to as the Zener diode.

When the reverse voltage reaches a certain level, the current flow increases exponentially, with the increase being controlled by an external resistor, also known as the Zener resistor. This increase in current flow is referred to as the Zener breakdown. The current flow then continues until a fixed reverse voltage, or Zener voltage, is obtained.

The CZRA4740-HF has a wide range of applications, due to its high breakdown voltage and low reverse leakage current. It is the perfect component to use when a large voltage drop and tailoring is required. The component is also very reliable and can be used in demanding applications.
