TVS diodes, or Transient Voltage Suppressors, are devices designed to protect sensitive electronics like integrated circuits from electrical hazards. The TVS diode TV15C171J-G, manufactured by Toshiba, is specifically designed to protect these circuits from overvoltage or transient voltage conditions. This diode is bidirectional and has a low standoff voltage requirement. Additionally, its high surge capability and fast response time make it an ideal choice for circuit protection.

Features and Specifications

The TV15C171J-G is a bidirectional transient voltage suppressor. It features a low breakdown voltage of 15V and a surge capability of 13.5A (8x20μs). It has a fast response time of 6.0ns, making it well-suited for protection against high-frequency transients. Other features include a low leakage current of 10μA Max, operating temperature range from -55°C to 125°C, and a lead-free, halogen-free design for increased environmental performance.

Application Field and Working Principle

TVS diodes are typically used in the automotive and industrial electronics markets to provide overvoltage protection. They can be used to protect circuits like integrated circuits, motors, and power cables. The TV15C171J-G is ideal for protection against short-term, high-energy transients such as induced lightning, overvoltage due to load dump, and negative transients. It can also be used in capacitively-loaded circuits such as oscillator circuits.

The TV15C171J-G diode works by clamping the voltage to a safe level when a surge of electricity occurs. It is designed to absorb and disperse energy from an electrical transient, while preventing the current from reaching the protected circuit. When the overvoltage is present, the device conducts the current from anode to cathode, clamps the voltage and dissipates the energy at the same time.

Conclusion

The TV15C171J-G is a bidirectional transient voltage suppressor designed to protect sensitive electronics from overvoltage and transient voltage conditions. Its low standoff voltage requirement, high surge capability, and fast response time make it an ideal choice for circuit protection applications. It is suitable for protection against short-term, high-energy transients and can be used in capacitively-loaded circuits.
