Diodes - Zener - Single

The BZX84C24W-7-F is a glass passivated, high power voltage stabilizing diode with a breakdown voltage at 24V. It is a type of a three-layer, avalanche characteristic, PN junction diode. It is designed for operation with a reverse voltage of up to 85V and a power dissipation of 1W.

Application Field

Due to its robust construction and low price, it is a popular choice for many general applications including voltage regulator circuits, clipper-coupler circuits, in-rush current limiters and generator protection circuits.

One of the advantages of using a BZX84C24W-7-F for voltage regulation is its ability to hold a certain voltage level steady at the output despite variation on the input. This makes it suitable for applications that require stability in the output voltage, such as powering appliances in a home.

Working Principle

The working principle of a BZX84C24W-7-F is based on the avalanche breakdown mechanism. It operates as a low resistance path when the voltage across it exceeds its breakdown voltage. This mechanism produces a relatively low voltage drop across it, which makes it suitable for use in voltage regulation circuits.

The internal structure of the BZX84C24W-7-F consists of a P-type semiconductor material sandwiched between an N-type material and an N-type semiconductor. In a forward bias condition, current flows from the positive terminal of the device to the negative. When the voltage across the device exceeds its breakdown voltage, a current path forms and a large reverse current flows instead.

The breakdown voltage of the device determines the voltage drop across it when the reverse current is flowing. This voltage drop remains relatively constant over a wide range of operating conditions and is easy to adjust.

The BZX84C24W-7-F is a reliable and cost-effective device that can be used in a variety of applications. It can be used to regulate output voltage, limit in-rush current, protect generators and provide a low impedance path in clipper-coupler circuits.
