1.5SMC9.1AHR7G

TVS (Transient Voltage Suppressor) diodes are a type of semiconductor device used to protect sensitive electronic equipment from high voltage transients. The 1.5SMC9.1AHR7G is one such TVS diode, designed to provide over-voltage protection for industrial applications. This article will discuss the application fields and working principles of the 1.5SMC9.1AHR7G.

Application Fields

The 1.5SMC9.1AHR7G TVS diode is designed for applications in the industrial sector, such as uninterruptible power supplies (UPS), data acquisition systems, energized controllers, industrial automation systems, and communications systems. It is suitable for both AC and DC applications, and offers high surge protection capabilities. It can operate in temperatures ranging from -65°C to +175°C.

Working Principle

The 1.5SMC9.1AHR7G operates on the principle of a zener diode. When the voltage across its terminals reaches a certain level (the breakdown voltage), the diode begins to conduct. This causes a drastic reduction in its reverse resistance, allowing current to flow through the device and thereby limiting the voltage across its terminals. The 1.5SMC9.1AHR7G offers improved protection against transients compared to traditional zener diodes, thanks to its superior reverse breakdown voltage. It also provides strong clamping capability, allowing it to handle higher surge currents.

Conclusion

In conclusion, the 1.5SMC9.1AHR7G is a TVS diode designed for industrial applications. It operates on the principle of a zener diode, and offers improved protection against transient voltage spikes. It is suitable for both AC and DC applications, and can operate in temperatures ranging from -65°C to +175°C.
