Introduction to TVS- Diodes

TVS (Transient Voltage Suppression) diodes are semiconductor devices that act as a protective component between a power source and an electronic device or a power device. A TVS diode is capable of handling high peak transient voltages while limiting the current flowing through the device, thereby protecting the device or circuit from damage due to over-voltage transients.TVS diode technology can provide a level of safety and reliability that is not possible with other types of transient protection devices, such as varistors or MOVs. They can also provide superior response times while protecting the system in a cost-effective manner.

TV50C400JB-G Application Field and Working Principle

The series TV50C400JB-G is a bidirectional ultra fast Silicon Avalanche Diode designed for ESD, surge and lightning protective applications. It is designed to protect low-capacitance interface circuits that interface between data and telecommunications networks, bus interfaces, cable modems, power lines, and optical fibers. By suppressing the high-voltage spikes within the normal operating parameters, the device will help to ensure proper operation of the circuits downstream.The TV50C400JB-G is a reverse-biased, high-diode voltage device functioning in an avalanche breakdown mode. When exposed to high-voltage spikes, the diode starts conducting, thus protecting the circuit from any electrical stress. The diode has a low dynamic and static capacitance which provides high-frequency protection at the interface inputs. The device can also handle high reverse voltage while achieving a low clamping voltage, making it ideal for applications where the insulation resistance must be maintained.In terms of performance, the TV50C400JB-G can handle repetitive surges up to 1500W peak pulse power per line with a 10/1000us waveform. The 5ns reverse-recovery time with minimal ringing helps to ensure accurate electrical performance in highly demanding applications. The TV50C400JB-G features RoHS compliant and IEC61000-4-5 compatible capabilities.

Conclusion

The TV50C400JB-G is a reliable, robust, and cost-effective transient voltage suppression diode designed to protect electronic devices and circuits from electrical stress. It can handle repetitive surges of 1500W peak pulse power per line with a 10/1000us waveform and 5ns recovery time. In addition to its performance benefits, the diode also features RoHS compliant and IEC61000-4-5 compatible capabilities. Its combination of features makes it a great choice for a variety of applications.
