ATV04A450JB-HF is a 600 watt unidirectional transient voltage suppression (TVS) diode with mounting brackets from Littelfuse, a leading supplier of automotive, circuit protection and rectifier and diode products. It offers high surge current and high EMI/RFI noise suppression, as well as short reverse recovery time and fast rise time. The ATV04A450JB-HF is suitable for use in automotive, industrial, telecom and consumer electronics applications.

Applications

The ATV04A450JB-HF is a robust transient protection solution designed to protect circuits from voltage transients. It is ideally suited for a wide range of automotive and industrial applications, including: transceiver ports, MOSFET gates, battery protection, overvoltage protection, reverse battery protection, and line protection. It\'s also a great option for telecom and consumer electronics devices, such as set-top boxes, automotive audio systems, DVD players and smart phones.

Working Principle

The ATV04A450JB-HF works on the principle of reversible avalanche breakdown, where an avalanche breakdown occurs if the reverse voltage applied to the diode reaches a certain level. This causes a very short pulse of current to flow through the diode as it attempts to restore the voltage. The intense current surge is then quickly limited by the diode\'s built-in clamping, which effectively protects the circuit from overvoltage transients.The ATV04A450JB-HF has a low reverse leakage current even at room temperature. Its high peak pulse current and low dynamic impedance also help protect circuits from voltage transients and ESD. Furthermore, its built-in fusing feature ensures that the ATV04A450JB-HF remains safe and reliable during extreme overloads, and it also features a unique fast-acting thermal shutdown protection feature.

Conclusion

The ATV04A450JB-HF is ideal for automotive, industrial, telecom and consumer electronics applications, providing robust ESD, over-voltage and reverse battery protection. Its low reverse leakage current, high peak-pulse current and low dynamic impedance ensure an effective protection against a wide range of transient voltages. In addition, its built-in fusing and fast-acting thermal shutdown protection features ensure the highest level of safety and reliability even under extreme conditions.
