Working Principle

SA7.0CA R0G is a uni-directional type of TVS diode. The diode’s breakdown voltage is 7.0V, its warm-up current is 50mA, and its peak pulse power is 1.5kW. This TVS diode works by essentially short-circuiting any voltage transients that exceeds its rated breakdown voltage.In operation, SA7.0CA R0G acts to limit the voltage excursions of any transient voltages. This protection is provided when the voltage transient reaches the breakdown voltage of the diode, causing the diode to become conductive and short-circuit the transient voltage, thus limiting the exposure to sensitive circuitry.In order to ensure that SA7.0CA R0G can respond to transients quickly, it is designed with high reverse leakage current and low capacitance. This ensures the diode can quickly respond and short out any high-magnitude, high-frequency transients, protecting the electronics from damage.

Conclusion

SA7.0CA R0G is an unidirectional Transient VoltageSuppression (TVS) diode which is designed to limit the voltage excursions of voltage transients by short-circuiting any voltage that exceeds its rated breakdown voltage.It can be used in a wide variety of applications such as consumer electronics, telecommunications equipment, personal computers, automotive and industrial electronics. The diode is designed with high reverse leakage current and low capacitance, ensuring it can quickly respond to high-magnitude, high-frequency transients.
