Z4KE200HE3/73

Diodes - Zener - Single

The Z4KE200HE3/73 Zener Diode is a general purpose single diode, widely used to regulate and limit the voltage within an electronic circuit. It is classified in the ‘Single’ category, as it is a single diode rather than a diode package or an array of multiple diodes.

Application Field

This Zener Diode provides voltage regulation, voltage clamping and signal clipping among functioning circuits – typically to control and protect the operation of electronic equipment. As it can be used to regulate voltage by maintaining calibrated operating voltage for correct operation, Z4KE200HE3/73 is ideal for use in winding connections and power supplies, as well as audio equipment.

Working Principle

Essentially, the Z4KE200HE3/73 has two diodes connected in series, backward. The diode connected in the forward direction works as a normal rectifier, allowing current flow that is proportional to the applied voltage. The Z4KE200HE3/73 has an built-in Zener voltage, which when reached enables the Zener diode to start conduction in the reverse direction. The current that flows in the reverse direction is limited to a few milliamperes and is independent of the voltage; this current contributes to the breakdown of the applied voltage, limiting and regulating it. The Zener voltage is measured between the anode and cathode, ensuring that it is kept constant, desirable for many industrial and commercial applications.

Conclusion

Given its reliable operation, universal application field and low cost, the Z4KE200HE3/73 is an excellent choice for a variety of equipment and machinery. Its wide range of features is also beneficial, since it can be used in a variety of situations to regulate and protect electronic equipment.
