Zener diodes are used to regulate voltage by introducing a breakdown voltage into circuits. The BZX84B75-HE3-18 Zener diode is designed to offer reliable voltage control in circuits operating up to 18V. This component provides excellent performance when used in power stabilizing and voltage clamping circuits.

The BZX84B75-HE3-18 is a single Zener diode that is housed in a leaded package with DO-35 outline. As with all Zener diodes, it exhibits a reverse bias that causes the diode to break down and produce a regulated voltage. It features a Zener voltage of 75V with a maximum Zener impedance of 5Ω. Other specifications of this component include a maximum operating temperature of 125°C, a power dissipation of 500mW, and a current rating of 200mA for continuous operation.

How does the BZX84B75-HE3-18 work? When a voltage supply of 75V or lower is connected to the anode and cathode, the diode acts as an open circuit. When the voltage rises above the Zener voltage of 75V, the diode turns on and allows current to flow in the reverse direction, producing a regulated voltage of 75V. This stabilizes the voltage supply, preventing it from rising above the Zener voltage.

The BZX84B75-HE3-18 diode is mainly used in power supply circuits. Its regulated voltage output helps to maintain the output voltage and current within the required levels. This component can also be used in circuits that require electrical isolation, such as automotive systems. Additionally, it can be used in voltage clamping applications, where it can protect electronic equipment from voltage spikes.

This single Zener diode is an ideal choice for circuits with an operating voltage up to 18V and for applications that require reliable voltage control. It offers excellent performance and is a cost-effective solution for voltage regulation and voltage clamping.
