TVS or Transient Voltage Suppressors are semiconductor-based electrical components used to protect other electronic components from damage caused by voltage transients, which are short duration voltage spikes lasting a few nanoseconds to milliseconds. This protection is also known as ESD or Electrostatic Discharge protection. The SMC series of TVS from LL5K is a bi-directional and bidirectional ESD suppressor with low-leakage protectio and low clamping voltage for protection against overvoltage or ESD transient.

The SMC5K20AHM3/I application field is mainly used to protect electronic components in ESD protection applications. This SMC5K20AHM3/I also supports wide operating temperature range from -40°C to +150°C. The package includes SMC5K20AHM3/I, 4 x 10mm2 PVC Tube, and a SMA antenna connector in order to provide effective ESD protection.

The working principle of the SMC5K20AHM3/I is based on the concept of breakdown voltage. In essence, when the voltage applied exceeds the breakdown voltage of a diode, a small current flows, which creates a voltage drop and hence provides an effective protection. The ESD protection provided by SMC5K20AHM3/I is based on the same principle. When a voltage transient occurs, SMC5K20AHM3/I automatically kicks in and releases the voltage by providing a low, clamping voltage. This ensures that the electronic circuitry connected to the SMC5K20AHM3/I is protected from the voltage transient.

SMC5K20AHM3/I has a high-temperature (HTR) low leakage (LLR) and high capacitance (HCC) which are the main functions for providing effective ESD protection. The HTR helps protect against over-voltage while the LLR feature helps to maintain low leakage of the ESD current. Lastly, the HCC feature helps to reduce the ESD voltage and offer the best clamping protection.

In conclusion, the SMC5K20AHM3/I is an efficient and effective Bi-directional and Bidirectional ESD suppressor for protecting electronic components from voltage transients. Its high temperature, low leakage and high capacitance features allow it to provide strong and reliable ESD protection. This makes the SMC5K20AHM3/I an ideal solution for any application where voltage transients are likely to occur.
