SA170ARLG

TVS diodes are defined as transient voltage suppression diodes, and they form an essential part of today\'s electronic systems. The SA170ARLG is an advanced three-terminal transient voltage suppressor device designed to provide surge protection to critical points in electronic equipment. As the demand for rapid response to large transients continues to increase, the SA170ARLG is designed to meet the specific requirement of combination-mode protection. The device has fast response to transient events with minimal power derating.

Application Field

SA170ARLG is designed for transient protection in a variety of surge applications like Ethernet protection, in line protection, or low-side protection. It is greatly suitable for use in PCBs, where size is a factor. SA170ARLG delivers superior performance and it has an extremely low parasitic capacitance. The device works at a high-temperature operation and shows durable performance in a wide range of temperatures. The overvoltage sensitivity is also very low.

Working Principle

The SA170ARLG comes with two diodes connected in a series configuration and acts as an ideal TVS. The current flow is reflected by the response time depending on the peak current of the surge event. The sum of the breakdown voltages of the two diodes determines the device voltage rating. These diodes become operable when the voltage accumulated across them is greater than their breakdown voltage rating. This device is suitable for AC or DC-driven surge protection and fast-rising and decaying-edge surge protection.

The SA170ARLG is designed with an active surge protection profile that helps to further reduce the component power loss during active operation. The device ensures no inrush current protection and fast response to sudden surge events. The device efficiently absorbs power during a transient and limits the flow of current. The device releases the stored energy in order to protect against any future transient event.

Conclusion

The SA170ARLG is an advanced TVS diode designed to protect against fast-rising transient events. The device ensures low clamping and high transient absorption along with low thermal resistance. The device has fast response time and low parasitic capacitance and can operate at high temperature operation. The device possesses excellent surge protection and provides low overvoltage sensitivity.
