TV15C280J-HF Circuit Protection

TV15C280J-HF

TV15C280J-HF, also known as a transient voltage suppressor (TVS) diode, is an electronic component designed to protect circuit components and systems from overvoltage caused by load-dump, shifting ground potential, and electrostatic discharge (ESD). TVS diodes are one type of voltage-clamping device, which works by diverting excess current away from a circuit to avoid damage. By diverting the current, the voltage is clamped to a level below the breakdown voltage of the diode.

TV15C280J-HF is a TVS diode specifically designed to protect automotive electronics and 12 VDC industrial systems. It is a bi-directional type, which means it can handle currents that flow both in the forward and reverse direction. The device has a breakdown voltage of 15 VDC and can handle power levels up to 280 watts (W). The TV15C280J-HF is constructed with silicon-oxide passivation and encapsulated in a black plastic J-lead through-hole package.

Application Field

The TV15C280J-HF TVS is well-suited for applications such as automotive systems, industrial control systems, consumer electronics, and computer systems. In automotive applications, the TVS can be used to protect powertrain, climate control, and infotainment systems from overvoltage caused by load-dump, shifting ground, and ESD. In industrial control systems, it can be used to protect cable interfaces, control boards, and other pieces of equipment from transient voltage. Similarly, the TVS can be used to protect consumer electronics, such as DVD players and DVD recorders, and computer systems from overvoltage.

Working Principle

A TVS diode works by quickly dissipating a surge of current away from a circuit. When a surge of current flows through the device, the voltage across it changes rapidly. This rapid change of voltage causes an avalanche breakdown, which results in the current being diverted away from the circuit. By diverting the current, the voltage is clamped to a level below the breakdown voltage of the diode.

TV15C280J-HF has a reverse breakdown voltage of 15 VDC, meaning that if the voltage across the diode exceeds 15 VDC, the current will be diverted away from the circuit. The device also has a power dissipation rating of 280 W, meaning it can handle up to 280 watts of power without damage. The TV15C280J-HF is designed to respond quickly to transient events, making it well-suited for applications where fast response is required.

Conclusion

TV15C280J-HF is a TVS diode designed to protect 12 VDC automotive electronics and industrial control systems from overvoltage caused by load-dump, shifting ground, and ESD. It has a reverse breakdown voltage of 15 VDC and can handle power levels up to 280 watts. The TV15C280J-HF is constructed with silicon-oxide passivation and encapsulated in a black plastic J-lead through-hole package, making it well-suited for applications in automotive systems, industrial control systems, consumer electronics, and computer systems.
