BZX84-C22,235

The BZX84-C22,235 is a widely used single Zener diode. It is part of a broad range of Zener diodes available through NXP Semiconductors, and its applications span across various industries. The device is typically used in voltage regulation circuits for components such as transistors, radios, and other electronics. This article seeks to provide an overview of the working principle and application field of this particular device.

Working Principle

A Zener diode is composed of an area of silicon, between two PN-junctions. When the forward voltage applied to the diode exceeds its breakdown voltage, current suddenly increases. This rapid increase in current is known as the Zener effect. The BZX84-C22,235, in particular, has a breakdown or Zener voltage of 22 volts.

When the Zener diode is connected in reverse bias, the circuit behaves as a voltage regulator. As long as the applied voltage remains within a certain range, the diode maintains the regulated voltage level. This is because when the applied voltage exceeds the breakdown voltage of the diode, current will rapidly increase through the diode and dissipate. Thus, the voltage drop across the Zener diode is regulated.

Application Field

The BZX84-C22,235 is a widely used Zener diode in the electronics industry, including automotive, consumer and computer applications. It is typically used in circuits with transistors and other electrical components. In addition, the diode may be used in thermistors and other temperature sensitive devices. It can also be used as a voltage protection device, where it can monitor and regulate the amount of voltage being applied to a circuit.

This particular Zener diode can also be used in power supplies as a voltage reference or as a precision voltage regulator. Zener diodes are frequently used in combinations with series resistors, diodes, and transistors to clip, clamp, or regulate voltage signals.

In addition, the diode can be used in some signal classification applications, such as the pulse-width modulation of digital signals, the decrease of signal amplitude, and the elimination of higher frequency harmonics. This Zener diode is also used in convergence correction errors for television displays, and in radio receiver circuits for protection against static discharges.
