TV15C540J-G Circuit Protection

TV15C540J-G is a silicon transient voltage suppressor (TVS) diode. The TVS diode is designed to protect voltage sensitive components, such as printed circuit boards (PCBs) and integrated circuits (ICs) from potentially destructive excessive electrical transients.

Application Field

TV15C540J-G is an automotive grade TVS diode that is used in a broad range of automotive and other vehicle applications. It is designed to protect against transient voltage spikes up to 15V, with a breakdown voltage of 24V. It is ideal for applications including automotive infotainment, HVAC systems, telematics systems, and automotive safety systems. It can also be used in other high-voltage spike induced applications, such as consumer electronics, solar panels, and LED lighting systems.

Working Principle

The TV15C540J‑G is a bidirectional device and works by diverting excess transients away from the protected components. It operates by absorbing the peak of the electrical transient and clamping its amplitude to a safe level. The TVS diode is designed to have its breakdown voltage set slightly higher than the peak expected value of the voltage spike, allowing the energy to be diverted away from sensitive components.The peak surge handling capabilities are dependent upon the diode’s capacitance and its size. TVS diodes have a much higher peak power handling capability than traditional diodes, since they can absorb far higher levels of energy during their clamping action.

The TV15C540J-G is capable of handling both high-energy fast transients as well as slow, high-power transients. It can provide fast clamping action on high-energy, fast transients, and can also provide sufficient clamping on the slower transients. Its low clamping voltage and fast response time make it an ideal protection device for applications that require high levels of safety.

Conclusion

The TV15C540J-G is an ideal protection device for applications requiring both high-energy fast transients and slow, high-power transients. Its low clamping voltage, fast response time, and wide range of application fields make it an ideal choice for many designs. The TVS diode is designed to have its breakdown voltage slightly higher than the peak expected voltage spike, allowing the energy to be diverted away from sensitive components. As such, it can help to ensure maximum safety for a design, protecting components from potentially destructive electrical transients.
