TVS - Diodes (Transient Voltage Suppressor) is a semiconductor device, designed to protect electronic circuits from undesired voltage transients and spikes. The most popular type of TVS diodes are PTVS24VS1UR and 115.

Application Fields of PTVS24VS1UR and 115 TVS Diodes

These TVS diodes are used for various circuit protection scenarios, such as protecting against Electrostatic Discharge (ESD) and Electro-Magnetic Interference (EMI). On industrial power supplies, they protect against surges when turning off the power supply or when a short circuit occurs. They can also be used to protect against voltage transients in a wide range of circuit applications.

The PTVS24VS1UR and 115 can be used to protect different components of a circuit, such as power supply lines, ICs, discharge circuits, etc. In automotive and industrial applications, they are widely used to protect against electrical transients due to lightning strikes, as well as to protect against overvoltages arising from sudden changes in the power supply.

Working Principle of PTVS24VS1UR and 115 TVS Diodes

At normal operation, the TVS diode acts like an open circuit, allowing no current to pass through. When an overvoltage occurs, the TVS diode will switch to a conducting state, allowing current to pass through the diode and thus diverting the current away from the circuit it is protecting.

When the overvoltage is gone, the diode switches back to an open circuit state and will be ready to protect the circuit from the next surge. This response time is very fast, usually in the order of a few nanoseconds, allowing the TVS diode to protect the circuit before any damage can occur.

The PTVS24VS1UR and 115 have a maximum Surge Current of 24A and a Maximum Peak Pulse Power of 1500W. The 115 can handle a Repetitive Peak Reverse Voltage of up to 600V, and the PTVS24VS1UR can handle up to 1200V. Both diodes have standoff voltages of 5V, which means they will not start to conduct current at voltage below 5V, allowing them to be safely used in a wide range of applications.

Conclusion

The PTVS24VS1UR and 115 TVS diodes are versatile components, used in a wide variety of circuit protection applications. Their fast response time and high surge capabilities make them ideal for protecting against voltage transients and EMI in all kinds of devices and circuits.
