Features of SMC5K17A-M3/I TVS Diodes

The SMC5K17A-M3/I TVS diode has several features that make it well-suited for many applications. It has a low breakdown voltage (Sharp Interval 8V) requires very little input current to achieve this, and can dissipate very high peak pulse powers without degrading. It also has a high surge energy rating, and a long standoff voltage (Vmin: 8V) as well.The SMC5K17A-M3/I also has an extremely low operating temperature (Tj=-40ºC to+125ºC) and can handle up to 10kA peak pulse current. Additionally, it has high ESD protection levels (Human Body Model 4kV, Machine Model 2kV) and low leakage current (<0.1μA). The diode also has a very high reliability rating, and its RoHS compliant shielding construction makes it environmentally friendly.

Working Principle of SMC5K17A-M3/I TVS Diodes

The working principle of the SMC5K17A-M3/I is simple yet efficient. When a voltage surge occurs, the diode will conduct the excess current and absorb the energy of the surge, effectively protecting the sensitive electrical components.The SMC5K17A-M3/I consists of a sensitive gate transistor and an avalanche diode. When the reverse voltage applied to the diode reaches the critical level, the avalanche diode, or Zener diode, conducts the current and the gate transistor turns on, causing the voltage across the diode to drop. This drop in voltage prevents the surge from reaching the sensitive components, protecting them from damage.

Conclusion

The SMC5K17A-M3/I is a versatile and reliable TVS diode. It is suitable for a variety of applications, and its features make it well-suited for industrial automation, automotive, telecommunication, and consumer electronics.
