ATV50C160JB-HF Application Field and Working Principle

TVS - Diodes are semiconductor devices which protect sensitive electronics from energy disturbances, usually transients, which could otherwise damage the equipment. ATV50C160JB-HF is a diode bidirectional TVS which offers a low clamping voltage and a fast response. This TVS is designed to protect voltage sensitive electronic devices from high energy voltage spikes, such as during vehicle start-up, system switch-off, or electrostatic discharges.

Application Field

Due to its low clamping voltage and small signal leakage current, the application field for ATV50C160JB-HF is wide, especially for in-vehicle and industrial equipment. It is designed to protect electronic circuits such as ECUs, controllers, microprocessors, and power switches from high-energy transients, like electrostatic discharges, pulse currents, surge currents, and other voltage events. This diode is suitable for usage in 12/24V automotive system, industrial and commercial equipment, transportation equipment, communication system, and measuring and controlling equipment.

Working Principle

The main working principle for ATV50C160JB-HF is based on the avalanche breakdown. When the forward voltage applied to the semiconductor diode exceeds the avalanche breakdown voltage, a large surge current will flow through the diode. This high current will begin to flowing with the diode voltage reaching its PIV (peak inverse voltage). If the spike is high enough, the diode will become conducting and reduces the peak voltage on both the positive and negative lines. The device will begin to breakdown and the voltage will move towards the clamping voltage.

The key advantage of this diode is its low clamping voltage. ATV50C160JB-HF provides an excellent combination of low clamping voltage, low reverse leakage current, and fast response time. This diode also has a very low temperature coefficient which ensures the device will remain stable under extreme temperatures. This diode is offered in an SMB package, with a peak pulse power rating of 100W.

Conclusion

ATV50C160JB-HF is a bidirectional TVS diode which is designed to protect against high energy voltage spikes. It offers a low clamping voltage and a fast response time. This diode is suitable for protecting ECUs, controllers, microprocessors, and power switches from a range of voltage events. The ATV50C160JB-HF also has a very low temperature coefficient and a peak pulse power rating of 100W. This diode is ideal for a range of applications, such as in-vehicle and industrial equipment.
