TV06B401JB-HF is a unidirectional, bidirectional or multipath TVS diode that is designed to protect V1.0, V1.0 A, V2.0, V2.0 A, V2.2, V2.2 A, CTT, and mini coaxial channels from electrostatic discharge (ESD) and surge-induced overvoltage threats. This device is available in various ESD-rated packages ranging from SOT-23-5, SOT-23-6, SC70-6, SOT-89 to TSOP-6. The maximum peak power rating is up to 4.0 kW for unidirectional, bidirectional, and multipath protection.

The TV06B401JB-HF is designed and tested to EIA/TIA standards to meet the stringent requirements of IEC61000-4-2 (ESD): Air-15kV, Contact-8kV; IEC61000-4-4 (EFT): 40A (5/50); and IEC61000-4-5 (surge): 2kA (tP=8/20µs). It has fast response times, low leakage currents, and low capacitance, making it ideal for a variety of applications. Furthermore, it provides excellent performance over multiple ESD events.

Application Field

The TV06B401JB-HF is used in a variety of applications, including computer, telecommunications, industrial, consumer, automotive, medical, military, and aerospace components that are vulnerable to ESD, EFT, or surge threats. It is especially suitable for high-speed data-line protection, such as USB, FireWire, 1394, HDMI, and Display Port links. It can also be used for telecommunications, CATV, cable modems, xDSL modems, power and ground lines to protect against noise and ESD.

Working Principle

The TV06B401JB-HF uses a unique avalanche breakdown region that is triggered when exposed to high voltage. Upon encountering this high voltage, the device will break down and clamp the voltage back to a safe level. Clamping reduces voltage overshoot and transient voltage peaks and prevents device damage caused by these overvoltage threats.

The TV06B401JB-HF has a low dynamic resistance that helps limit the voltage rise time, thus providing protection against pulse transients and noise pulses. Additionally, the device does not require any external components, making it less expensive and easier to incorporate into protective circuits.

The TV06B401JB-HF is self-protecting during normal operation, and has a built-in crowbar circuit that can trigger if a short circuit or direct short to ground occurs. The protection diode will divert current to protect the internal TVS diode and other circuit components from being damaged.

Conclusion

The TV06B401JB-HF is a versatile TVS diode with a wide range of applications in almost any industry. It provides excellent protection from ESD, EFT, and surge threats and can be used for USB, FireWire, 1394, HDMI, and Display Port links. It is easy to incorporate into protective circuits, does not require any external components, and self-protects against short circuits and direct shorts to ground. The TV06B401JB-HF is an invaluable tool for protecting vulnerable components, and is a must-have for any design engineer.
