A TVS (Transient Voltage Suppressor) diode, such as the ATV04A100J-HF, is a fast-acting semi-conductor device that is designed to protect electronic circuitry from damage due to high voltage transients caused by lightning, electrostatic discharge, or other high energy events. TVS diodes provide an alternative to the traditional MOV (Metal Oxide Varistor) for maximum protection against high voltage transients. The ATV04A100J-HF is a high performance dual diode TVS that is ideal for a variety of applications.

The ATV04A100J-HF is designed to operate in a wide variety of applications. It can be used as a power supply transient protection device, a line protection device for low capacitive load systems, and as a protection device for DC-DC converters, DC motor controllers, and AC motor drives. It is also suitable for use in control unit power and data line protection, as well as for application in control circuitry. The ATV04A100J-HF has operating temperature range of -55°C to 125°C, with an ambient air temperature range of -40°C to 85°C.

The ATV04A100J-HF is a dual diode TVS, which means it has two diodes that are each capable of handling different types of high voltage transients. The first diode has a lower capacitive load and is designed to protect against high-frequency transients such as ESD (electrostatic discharge). The second diode is designed to protect against low- to medium-frequency transients such as lightning strikes.

The working principle behind TVS diodes is simple. They are designed to provide fast-acting protection from transients by rapidly diverting the transient current away from the protected circuit. The ATV04A100J-HF has a reverse standoff voltage (VRWM) of 18V and a peak pulse current of 100A, which means that it can handle up to 100A of surge current before it begins to fail. As the transient voltage increases beyond 18V, the diode will begin to conduct current, thus protecting the downstream circuit.

In summary, the ATV04A100J-HF is a high performance dual diode TVS that provides fast acting protection from high voltage transients. It is designed for a wide variety of applications, including power supply transient protection, line protection, and protection for DC-DC converters, DC motor controllers, and AC motor drives. Its reverse standoff voltage is rated at 18V, and it has a peak pulse current rating of 100A.
