Introduction:TVS (transient voltage suppressor) diodes are discrete components designed to provide effective over-voltage and surge protection to the electrical system. P6SMB82CA-M3/52 is one of the most popular TVS diodes, which is widely used in the electronic system. This article provides an introduction to the application field and working principle of P6SMB82CA-M3/52, a popular TVS diode.Application Field:P6SMB82CA-M3/52 is widely used in various electronic products such as computers, cellular phones, tablets, servers, automation equipment, industrial controllers, etc. as a surge protector. It offers bi-directional protection to the host system, which can suppress the over-voltage of the system caused by inrush current, ESD, Telecom spike, lightning, low-energy surges, and other transient events. The P6SMB82CA-M3/52 device can be used in both positive and negative polarity.Working Principle:P6SMB82CA-M3/52 is a bidirectional device with two P-N junctions connected back-to-back. When using in positive polarity, the cathode takes a positive voltage across it while anode takes a negative voltage. The P-N junction in the cathode is forward biased while the junction in the anode is reverse biased.The working principle of P6SMB82CA-M3/52 is very simple. When the system voltage exceeds the maximum levels, the P6SMB82CA-M3/52 will reduce the voltage across its terminals to protect the system components. Moreover, the device can also clamp the voltage at a correct level so as to avoid any further over-voltage issues.When the device is subjected to reverse voltage, the junctions in both cathode and anode will remain in the off-state. In this situation, the cathode will be reverse biased while the anode will be forward biased. In other words, the device will not be triggered by the reverse voltage.Conclusion: P6SMB82CA-M3/52 is a widely used TVS diode that provides efficient surge protection for electrical systems. Its application field is wide-ranging and it also has a very simple working principle. The device can protect the system from transient voltages by providing bi-directional protection and clamping voltage at correct levels. Thus, the P6SMB82CA-M3/52 provides a great level of safety for the system.
