SA36CA R0G

TVS diode is an important component of the circuit system. It is widely used in signal protection and electrostatic protection applications. It can effectively protect the circuit system under various adverse working conditions, improving its reliability. SA36CA R0G is an advanced TVS diode. This article will explain its application fields and working principles.

Application Field

SA36CA R0G is a type of axial leaded TVS diode. It is usually used to protect signal input and output from electrostatic transient threats and surges. Thanks to its ultra low dynamic resistance, ultra compact design and high peak pulse power capability, it can provide an extremely reliable signal protection to PC or laptop interfaces, notebook computers and other computing systems. It is also suitable for small consumer electronics, such as medical test equipment, digital cameras, etc. Its peak pulse power is 360W and its clamping voltage 8.3V.

Working Principle

The TVS diode works by diverting the transient and surge currents away from the circuit elements that it is protecting. It is constructed of a junction of N-type and P-type materials. When triggered, the PN junction is forward biased and a current carrying channel (avalanche breakdown) is formed between the N-type and P-type regions. This current carrying channel provides the low resistance path which helps to quickly divert surge away from the protected circuit system.

SA36CA R0G has a fast and controlled response to transients, thus it can provide superior protection for your circuit system. It consists of a Zener breakdown mode and a Thermal breakdown mode. When the transient voltage across the diode exceeds the Zener breakdown voltage, the current will follow the Zener breakdown path and be diverted away. When the voltage exceeds the thermal breakdown voltage, the current will follow the thermal breakdown path and spread over the PN junction area, thus quickly dissipate any excess energy and protect the protected element.

Conclusion

SA36CA R0G is an excellent TVS diode which has an excellent protection against electrostatic transients and surges. It is widely used in signal and electrostatic protection applications. It has a fast and controlled response to transients and its peak pulse power is 360W and its clamping voltage 8.3V. This article has discussed its application fields and working principles.
