TVS - Diodes

Transient Voltage Suppressors (TVS) devices are used to limit the stress on electrical systems exposed to transient voltage spikes. The ATV06B181J-HF is a TVS diode designed to protect electronic circuits from electrostatic discharges and transients. This article will discuss the applications and working principle of the ATV06B181J-HF.

Applications

The ATV06B181J-HF is designed to provide protection from both electrostatic discharge (ESD) and transients. This makes it suitable for use in a wide variety of applications, such as: automotive electronics, aviation, consumer electronics, telecommunication, instrumentation and medical equipment.This diode is particularly suitable for ESD protection of equipment transmitting data over cables. Additionally, it has a low clamping voltage, making it ideal for circuits that require a low voltage limit.

Working Principle

The ATV06B181J-HF operates by clamping voltage transients across its terminals. It consists of two zener diodes connected in series between its cathode and anode terminals. If a voltage transient exceeds the breakdown voltage of either zener diode, the voltage will be fully or partially clamped to the breakdown voltage.When the transient is over, the current induced by the transient triggers a reverse recovery current, which is designed to quickly discharge the stored energy (voltage clamp) safely. This protects the circuit from further damage.The ATV06B181J-HF also features a temperature-compensated overvoltage protection circuit, which is designed to control and limit the clamping voltage to the specified maximum for the device.

Conclusion

The ATV06B181J-HF is a TVS diode designed to protect electronic circuits from electrostatic discharges and transients. It is suitable for a wide range of applications, including automotive electronics, aviation, consumer electronics, telecommunication, instrumentation and medical equipment. The diode consists of two zener diodes connected in series between its cathode and anode terminals. When a voltage transient exceeds the breakdown voltage of either zener diode, the voltage will be fully or partially clamped to the breakdown voltage. The device also features a temperature-compensated overvoltage protection circuit, which is designed to control and limit the clamping voltage to the specified maximum for the device.
