TVS - Diodes: GL12T-HG3-18 Application Field and Working Principle

TVS (Transient Voltage Suppression) diodes, also known as surge protectors, are an important component for protecting other electrical devices from transient voltage. The GL12T-HG3-18 is a high-reliability, low-power TVS diode, designed for use in consumer electronics applications.

Application Field of GL12T-HG3-18

GL12T-HG3-18 TVS diodes are ideal for protecting circuits from transient voltage caused by lightning strikes, electrostatic discharge (ESD) events, or other high voltage, short-duration pulses. The GL12T-HG3-18 can be used in many different consumer electronic applications, including computers, video equipment, and other small devices. It is especially well-suited for protection of IC pins, such as clock pins, and other sensitive components.

Working Principle of GL12T-HG3-18

The GL12T-HG3-18 works by clamping the incoming voltage before it can damage any connected electronics. When the voltage reaches a certain level, the diode will become conductive and begin to discharge the energy. This clamps the voltage and prevents it from rising any further, protecting the connected electronics from damage. The amount of energy the GL12T-HG3-18 can handle depends on several factors, such as the current, voltage, and pulse duration, but it can typically handle up to 1A of current at 8 volts.

Conclusion

The GL12T-HG3-18 is a reliable and low-power TVS diode suitable for many consumer electronics applications. It is able to protect sensitive components from transient voltages, and can handle up to 1A of current at 8 volts. With its high reliability and application versatility, the GL12T-HG3-18 is a great choice for circuit protection.
