TVS (Transient Voltage Suppressor) diodes are one of the most commonly used components in the field of electronics. In the event of excessive voltage transients in an electrical system, the TVS diode can act as a protective device to shield the connected components from damage. The SA22CHE3/73 is one of the many varieties of TVS diodes that are currently available on the market.

The SA22CHE3/73 is designed to fit a broad array of application fields. Its peak power dissipation specification reaches 1050W, making it suitable for all kinds of high power applications. It also features a low response time of 6nS, making it suitable for high frequency applications. The device also features excellent clamping performance, with a peak pulse current of 14A and a peak clamping voltage of 44.2V. This makes it suitable for a variety of voltage transient and surge protection requirements.

The SA22CHE3/73 device features two general modes of operation. The first is the linear mode, which is activated when the device is exposed to a steady input voltage that crosses the avalanche voltage threshold. This threshold is usually greater than 40V for the SA22CHE3/73 device. Once activated, the device will function like a low resistance resistor, allowing a DC current to flow through the system.

The second mode of operation for the SA22CHE3/73 device is the avalanche mode. This mode is initiated when a transient voltage transient greater than the avalanche voltage threshold is applied to the device. This voltage can range from peak currents of 10A to peak clamping voltages of 48V, depending on the application. Once the avalanche mode is triggered, the device will function as a high resistance resistor, allowing a very high current to flow through the system while the voltage is clamped to a maximum level. This limits the amount of damage to the connected components and also prevents the system from entering a potentially damaging overvoltage condition.

In conclusion, the SA22CHE3/73 device is an excellent choice for high power, high frequency, and voltage transient / surge protection requirements. Its response time of 6nS and peak power dissipation specification of 1050W make it an ideal choice for applications located in high temperature or stressful working environments. Additionally, its peak current of 10A coupled with its avalanche and linear modes of operation make it suited for a variety of application requirements.
