TVS (Transient Voltage Suppressor) Diodes are a type of semiconductor protective device that suppresses voltage surges by providing a path to ground during a high-voltage event. In this article, we’ll be exploring the application field and working principle of 5KP22-B, specifically.

Applications of 5KP22-B

The 5KP22-B is a bi-directional transient voltage suppression diode that is typically used to protect electronic circuits from voltage transients generated by inductive switching and lightning or electrostatic discharge. Often installed in automobiles, the 5KP22-B helps protect circuits from these high-voltage transients while allowing AC/DC signals up to +70V to pass through.

The 5KP22-B diode is often used in automotive applications, such as electric door locks, alarm systems, and entertainment systems. It is capable of suppressing transients from ±10V up to ± the 5KP22-B’s maximum reverse breakdown rating of 5kV. At its rated reverse power rating, the 5KP22-B provides surge current support of up to 10A.

The 5KP22-B TVS diode also has applications in the consumer electronics industry. This device is used in audio systems, electric/hybrid vehicles, and communication and fiber-optic equipment. As such, the 5KP22-B can be found in a variety of electronic devices, ranging from refrigerators to home security systems.

Working Principle of 5KP22-B

The 5KP22-B transient voltage suppression diode is a two-terminal, axially-leaded device that contains an internal zener element which provides voltage clamping action during an over-voltage event. During an overvoltage event, the diode acts by diverting the excessive current away from the protected circuit and into an external resistor. As a result, the protected circuit is kept safe from overvoltage conditions.

In normal operation, between the rated peak power rating, 5KP22-B acts like an efficient low voltage diode. It allows AC/DC signals up to +70V to pass through and has the unique capability to withstand up to 5kV in the reverse direction. The device also acts as a short-circuit protection device by limiting the current into the protected circuit when a short is applied.

The 5KP22-B diode also has built-in surge suppression and transient voltage limiting capabilities, which are essential for protecting sensitive circuits from unexpected electrical spikes. The device offers several important clamping advantages, such as high clamp audibility, low leakage current and fast response times.

Overall, the 5KP22-B TVS diode provides reliable protection for a variety of applications in the automotive and consumer electronics industries. This device offers superior protection from voltage transients without compromising the performance of the protected circuit.
