The SA36CAHA0G belongs to the TVS (Transient Voltage Suppressor) diode family. It is a unidirectional TVS diode that can offer superior protection against transients in a wide variety of applications. As the name suggests, it is designed to absorb and clamp transient voltages. It works by diverting damaging energy away from equipment, thereby protecting it from transients.

The device offers a breakdown voltage of 36V. It is designed to dissipate energy up to 400W (at 10/1000μs waveform) and provide a clamping voltage of 45V. It features an axial lead structure that makes it easier to install in any orientation. It has a do-35 (SOD-123 FL) package and a maximum leakage current value of 1mA @ 5V.

The primary applications of the SA36CAHA0G include automotive systems, power supplies, consumer electronics and computers. It can be used as a shunt regulator for suppressing overvoltage transients in DC power systems. It can also be used in conjunction with an optical signal in data or telecom systems for providing ESD protection. Additionally, it is useful when used in high-frequency signal transmission lines for protecting against EFT (Electrical Fast Transient).

The working principle of the SA36CAHA0G is based on the avalanche breakdown principle. It features a two-layer silicon structure that has a PN junction region between them. When the reverse voltage applied to the device exceeds the breakdown voltage, a large number of free electrons and holes are generated in the junction. The accelerated electrons multiplied in the region and form an avalanche. This avalanche increases the current exponentially and clamps the voltage across the junction.

In conclusion, the SA36CAHA0G is a unidirectional TVS diode used for protecting against transients. It has a breakdown voltage of 36V and provides a clamping voltage of 45V. It is designed to dissipate energy up to 400W (at 10/1000μs waveform). It is mainly used in automotive systems, power supplies, consumer electronics, and computers. It works by diverting damaging energy away from equipment and based on the avalanche breakdown principle.
