TV15C151J-G Circuit Protection

Transient Voltage Suppressors (TVS) diodes, also known as surge protection diodes, are two-terminal components used to protect a circuit from transient voltage surges. The TV15C151J-G is a particularly popular TVS diode. This article will explore the application field and working principle of the device.

Application Field of the Device

Generally speaking, the TV15C151J-G is designed for use in consumer and computer circuit protection applications. The diode can act as a guard against transient voltage and electrostatic discharges. Furthermore, it can be used in a variety of different products, including TVs, computers, digital cameras, monitors, and other electronics. Due to its compact size and low dissipation, it is well-suited for a variety of applications.

Working Principle of the Device

The TV15C151J-G is capable of clamping transient voltages up to 150 volts and is designed to operate at a steady state in the reverse direction. The device is comprised of two parts: an N-type (negative) and a P-type (positive) diode. The N-type is placed between the cathode terminal and the anode terminal and is designed to breakdown when the transient voltage exceeds the breakdown voltage. This helps limit the voltage by providing a low impedance path for the current.

The P-type diode is placed between the anode and the cathode, and is designed to reverse blocking when the voltage exceeds the reverse voltage rating. This helps protect the circuit from damage caused by excessive current due to the high reverse voltage. The device is also designed to conduct in the reverse direction when the voltage drops below the reverse leakage voltage.

Conclusion

The TV15C151J-G is a widely used transient voltage suppressor diode. It is designed to provide protection against transient voltage surges and electrostatic discharges, making it suitable for use in consumer electronics and computer circuit protection applications. The device is comprised of two parts: an N-type (negative) and a P-type (positive) diode, both of which work together to provide protection against voltage transients.
