TVS - Diodes

SMC5K15AHM3/I is a type of Transient Voltage Suppressor (TVS) diode produced by DevTech Electronics. This diode is primarily used for clamping and protection of sensitive electronic components from voltage transients and surges. It uses a matrix-based architecture to provide high-speed performance for signal line protection. It offers a maximum clamping voltage of 15 volts, which makes it more effective than standard Transient Voltage Suppressor (TVS) diodes in terms of protecting electronic components from voltage transients and surges.

Application Field

SMC5K15AHM3/I is mostly used for protecting sensitive equipment from voltage transients and surges, such as computers, mobile phones, tablets, etc. It is also used in consumer and industrial equipment to protect them from spurious signals produced by nearby power sources. Furthermore, it can be used in automotive and aviation electronics, where its high-speed performance plays an important role in protecting the system from overvoltage.

Working Principle

SMC5K15AHM3/I works on the principle of a unidirectional matrix-based architecture, which allows it to provide high-speed clamping performance for signal line protection. The working of SMC5K15AHM3/I can be understood by considering it to be made up of two key components. The first component is a Zener diode, which helps to absorb and dissipate the transient voltage that may enter the system. The second component is a polymeric resettable fuse that helps to reset the diode if it is overdriven. This combination helps the SMC5K15AHM3/I to provide robust protection to sensitive equipment by limiting the voltage surge and quickly resetting if it is overdriven. It also has an ESD withstand voltage rating for human body contact, which makes it suitable for use in consumer devices.

Conclusion

In conclusion, SMC5K15AHM3/I is a type of Transient Voltage Suppressor (TVS) diode used for clamping and protection of sensitive electronic components from voltage transients and surges. It utilises a matrix-based architecture to offer high-speed performance for signal line protection and has a maximum clamping voltage of 15 volts. It is mostly used in consumer and industrial equipment such as computers, mobile phones, tablets, etc. to provide robust protection.
