3KP22CA-B

TVS - Diodes

The 3KP22CA-B is a transient voltage suppressor diode designed to protect circuits from transients, over-voltages, and ESD. It is a bidirectional device with a power rating of 3 Watt, a maximum break down voltage of 22 volts and a low leakage current of 0.2 mA. The 3KP22CA-B can aid in preventing damage to circuitry due to transient voltage surges.

Application Field

The 3KP22CA-B is most commonly used in AC power line protection as well as cable protection from ESD. It can be used in any application where it is necessary to protect a system from voltage spikes such as in automotive and industrial applications. It can also be used in residential and commercial power lines in order to protect equipment from lightning surges.

Working Principle

When subjected to a voltage transient, the 3KP22CA-B will clamp the surge to a safe voltage level. This is done through the use of a Zener diode that is typically connected in reverse bias across the gate of a power MOSFET. The Zener diode is a voltage-regulating device that maintains a consistent voltage across its two terminals. In the presence of a voltage transient, the Zener diode will limit the amount of voltage present and thus protect the equipment from damaging voltages.

The 3KP22CA-B is designed to operate in temperatures ranging from -55ºC to +125ºC, and it has a high surge capability rating of 300A. It is rated for High-Temperature Long Life use (HTLL) for 115V systems. This product also features an ESD Protection of Level 4 (±15kV).

Conclusion

The 3KP22CA-B is an excellent and reliable choice for protecting circuits from transient voltage, over-voltages and ESD. It\'s wide range of application and reliable surge protection capability make it one of the most sought after transient voltage suppressor diodes in the market.
