TVS - Diodes, 1.5SMC10AHR7G Application Field and Working Principle

The 1.5SMC10AHR7G is an ultra-low capacitance, bi-directional transient voltage suppressor (TVS) diode. It is designed to protect low voltage circuits from destructive voltage transients, such as electrostatic discharge (ESD) and electrical surges. TVS diodes are commonly used in automotive, telecommunications, industrial, and consumer electronics applications.

Overview of TVS Diodes

A TVS diode is a fast-acting, nonlinear two-terminal device that is designed to protect electronics from destructive voltage transients and surges. Under normal operating conditions, it behaves like a forward-biased diode, allowing current to flow in one direction. When the voltage exceeds a certain threshold, the diode enters the breakdown region and conducts current in both directions, effectively clamping the voltage. The advantage of reducing circuit damage and eliminating the need for additional protection circuitry makes them suitable for many applications.

Operation of the 1.5SMC10AHR7G

The 1.5SMC10AHR7G is a bi-directional TVS diode with an ultra-low capacitance of 1 pF. It has a break-down voltage of 6.5V and a maximum pulse current of 10A. It is designed to protect low-voltage circuits from destructive transients. When exposed to a transient voltage surge, the diode\'s internal breakdown voltage is triggered and it begins conducting current in both directions. By doing so, it clamps the voltage to a safe level, preventing damage to the sensitive circuitry of the device. The 1.5SMC10AHR7G also has a low-capacitance, which helps reduce overshoot and undershoot issues. This low-capacitance helps ensure that the voltage is clamped at the minimum level needed, and prevents additional circuit damage.

Applications of the 1.5SMC10AHR7G

The 1.5SMC10AHR7G is suitable for a variety of applications, including automotive, telecommunications, industrial, and consumer electronics. In automotive applications, it can be used to protect ECM (Engine Control Modules), ABS (Antilock Brake Systems), and a variety of sensors from voltage transients due to ESD and power line surges. In telecommunications, it can be used to protect sensitive networks from voltage transients on the line. In industrial and consumer electronics, it can be used to protect circuits from ESD and other voltage transients.

Conclusion

The 1.5SMC10AHR7G is an ultra-low capacitance, bi-directional transient voltage suppressor diode that is designed to protect low-voltage circuits from destructive voltage transients. It has a break-down voltage of 6.5V and a maximum pulse current of 10A. It is suitable for a variety of applications, including automotive, telecommunications, industrial, and consumer electronics. By effectively clamping the voltage to a safe level, it helps to ensure that sensitive circuitry is not damaged by voltage transients.
