Introduction

1N6297AHE3_A/C is a transient voltage suppressor (TVS) diode designed by ON Semiconductor. It is a commonly used solution for protection against voltage transient and surges due to lightning and other sources. This device offers extremely fast response time, low capacitance, and low leakage current.

Application Field

1N6297AHE3_A/C is widely used to protect sensitive electronic circuits in automotive, telecommunications and consumer applications from overvoltage caused by lightning or other transients. This device can help to protect most of the semiconductor components, such as transistors, gain cells, MOSFETs, and others. It is also used to protect items such as memory cards, radios, and metal oxide varistor (MOV) elements.In high-power applications it can be used to protect circuit components from damage caused by rapid rise of voltages, such as when a high voltage from a cable is applied to a bus line. This device can also be used to protect wiring, communication lines, and other electronics.

Working Principle

1N6297AHE3_A/C consists of two diodes connected in series. These diodes provide an excess current path for the transient current, and once the transient voltage exceeds the diodes’ reverse breakdown voltage, the current begins to flow through the diodes. The total current will be determined by the resistance of the series circuit and the voltage that is applied across the two diodes. The device can withstand voltages ranging from -5V to +30V and is capable of absorbing pulses of up to 600W without damage. The typical peak power surge current is 0.9A, and the typical reverse breakdown voltage is 15V. The TVS diode is designed to protect against voltage transients and surges, not static electricity, which can be prevented with an electrostatic discharge (ESD) suppressor. The device is also not designed to reduce noise, which should be done with other suppression devices.

Conclusion

The 1N6297AHE3_A/C is an ideal solution for protection against voltage transients and surges due to lightning and other sources. This device has an extremely fast response time, low capacitance, and low leakage current, and is suitable for protecting sensitive semiconductor components. The device is easy to install, and can withstand voltages ranging from -5V to +30V as well as pulses of up to 600W. Although this device is designed to protect against voltage transients and surges, it is not designed to prevent static electricity or reduce noise.
