TVS diodes are vital components for protecting against destructive levels of static electricity and lightning strike. A SA22CAHE3/54 TVS diode is a unidirectional high-power transient voltage suppressor (TVS) diode used to protect systems against destructive electrical transients.

This device is designed specifically to protect sensitive electronic equipment in automotive, telecommunication, and industrial applications from destructive electrical transients. It is made using a high-power voltage clamping and is designed to provide high performance and superior surge capability.

The SA22CAHE3/54 offers excellent electrical performance for a wide range of applications. It is capable of withstanding overvoltages up to 26.4 V and has a maximum power dissipation of 4.4 W. The device has an Ultra-fast response time from <1ns typical and a clamping voltage of 22 V for 12/20 μs surge. This device is designed to operate within the junction to ambient temperature range of -40°C to +125°C. It is capable of handling inductive transients up to 5 kV/75 A and is tested with an open-configuration.

The working principle of the SA22CAHE3/54 is based on its power clamping circuit. The power clamping circuit allows the device to respond quickly to surges without dissipating any energy until the maximum peak power rating is exceeded. When this point is reached, the SA22CAHE3/54 will then clamp the voltage over the positive and negative rail of the power supply. This ensures that the system will not be damaged by any further over-voltage conditions.

The SA22CAHE3/54 is an ideal choice for automotive, telecommunications, and industrial applications such as high-voltage power supplies and equipment, industrial and medical diagnostic equipment, and automotive power supplies and motors. It can also provide reliable protection to automotive bodies, radios, computers, printers, and other consumer electronics. Its state-of-the-art electrical characteristics make it an ideal solution for protecting these critical applications from destructive electrical transients.
