TVS - Diodes

TVS (Transient Voltage Suppression) diodes are utilized to protect a circuit from high-voltage transients, also known as surge voltage. In particular, TV04A150JB-G is a Fast Response low-capacitance diode that provides reliable transient protection for equipment using High Speed Data Interfaces.

Application Field

The TV04A150JB-G is designed to meet the high-speed ESD (Electro-Static Discharge) and EFT (Electrical Fast Transient) requirements of IEC 61000-4-2/-4-4/-4-5/-4-12 standards. This type of transient voltage suppression diode is suitable for protecting High Speed Interfaces, such as HDMI, DSL, SCART, and USB 3.0 from the possibility of partial and/or total functional failure. Therefore, this device is ideal for use in products such as set-top boxes, LCD and Plasma televisions, digital audio players, etc.

Working Principle

TV04A150JB-G uses a unique low-capacitance zener diode structure, so the switching time is much faster than conventional TVS diodes’, capable of nanosecond-level response times. The working principle of the diode is governed by the ESD phenomena. When the diode is in an open state due to high surge voltage, the electrical current that flows through the diode creates a heat pulse. As this heat pulse is very short, it dissipates the excess electrical energy to avoid damage on the equipment.

TV04A150JB-G is able to stop ESD currents of up to 15 KV and EFT burst voltages up to 8 KV, while also providing low capacitance of 0.2pF to preserve signal integrity. With operating voltage ranges from 6 to 24V, the TV04A150JB-G diode has an impressive clamping voltage of typically 11V.

Conclusion

TV04A150JB-G is a high-quality transient voltage suppression diode from TVS - Diodes. This diode provides effective protection from highvoltage transients, specifically ESD and EFT standards. It also offers a fast response time, high clamping voltage, and low capacitance. This diode is perfect for the protection of High Speed Interfaces found in modern digital consumer electronics.
