TVS - Diodes are used in a wide variety of electronic applications, both commercial and industrial. The ATV15C170JB-HF specifically provides surge protection for high-power, multi-channel applications by protecting against transient voltage spikes. This can be critical during conditions, such as lightning strikes or power surges, which can cause catastrophic damage to sensitive hardware.

The ATV15C170JB-HF can absorb up to 15kA of surge, and provides a peak pulse current rating (IPP) of 1250 amps. Its operating junction temperature range is -55ºC to 175ºC and its rated standoff voltage is 170V. It also features a very low clamping voltage of 111 volts and a clamping energy Ecl of 110.6 Joules.

The ATV15C170JB-HF is especially suitable for applications that are exposed to high levels of transient voltage. It is designed to reduce the voltage of the transients to a safe level, using a combination of its two primary mechanisms: capacitance and power dissipation. The current that is generated by the transient is initially dropped across the capacitance and then further clamped by the clamping action of the junction barrier. The remainder of the energy is then dissipated as heat.

Additionally, the ATV15C170JB-HF also has an integrated N-channel MOSFET, which is used to provide short circuit and overload protection. When the unit is subjected to an over-voltage, the voltage causes the N-channel MOSFET to turn on and open the circuit until the voltage is reduced. This helps to protect the surrounding components from possible damage.

The ATV15C170JB-HF is well-suited to a wide variety of applications, ranging from consumer electronics and defense electronics to automotive and medical applications. It is ideal for products that will be exposed to high levels of transient voltages and can provide reliable surge protection. It is also a relatively inexpensive and efficient solution, making it a popular choice in the market.
