Introduction to TV04A201JB-G TVS - Diodes

TV04A201JB-G TVS - Diodes are a type of transistor-transistor logic (TTL) device, which are used to protect high voltage applications from overvoltage and other electrical faults. The device is fast switching, with a maximum surge rating of 20A, and a clamping voltage of 45 volts.The TV04A201JB-G diode provides superior protection against transients in applications such as power supplies, audio amplifiers, automotive power systems and telecom equipment. The device is highly effective in suppressing high-speed transients, with its low internal resistance and low capacitance values.

Applications and Working Principle

The TV04A201JB-G has a wide range of applications in consumer electronics, communication systems and power supplies. It is typically used in applications where large transient over voltages may occur, such as motor control circuits or inverters. The device can also be used as a protection circuit for equipment subjected to severe impulse voltages, such as electronic ballast.The working principle of the device utilizes the reverse breakdown voltage (Vbr) of its p-n junction, which allows it to rapidly clamp transient overvoltages when it is connected in parallel with a load. The device is composed of silicon, which makes it immune to transient overvoltages up to 150V. When a voltage greater than the Vbr is applied across the junction, the device diverts the current away from the load to ground. The junction\'s characteristic junction capacitance and internal resistance result in a fast response time and good clamping performance.The device also features an High Temperature Reverse Standoff Voltage (HT_VR) to limit circuit damage in higher temperatures. The HT_VR value is the breakdown voltage of the device at an elevated temperature. If the voltage applied to the junction exceeds this value in higher temperature, the TV04A201JB-G will also activate, preventing further damage to the circuit.

Conclusion

TV04A201JB-G television transient suppressor (TVS) diodes are highly effective in suppressing high-speed transients and in protecting a variety of consumer electronics, communication systems and power supplies from overvoltage and other electrical faults. The device utilizes the reverse breakdown voltage of its p-n junction to rapidly clamp transient overvoltages. It features an High Temperature Reverse Standoff Voltage to limit circuit damage in higher temperatures.
