TVS - Diodes

TVS - Diodes are specialized semiconductor devices used to protect sensitive electronic systems, usually against surges such as ESD (electrostatic discharge), EFT (electrical fast transients) and lightning strikes. The SMA6J100CA-TR is one of such devices that has proven effective in various applications.

SMA6J100CA-TR Application Field

The SMA6J100CA-TR is ideally suited for use in mobile phones and other devices that use USB chargers or cables. The surge suppression device is also suitable for use in the automotive industry, home appliances, consumer electronics, electronic games, digital entertainment systems, and computer systems.

The device\'s low capacitance allows it to be used in LED lighting systems as an effective protection against ESD and EFT. Its bidirectional mode of protection also maximizes the survival rate of sensitive microcontrollers and integrated circuits.

SMA6J100CA-TR Working Principle

The SMA6J100CA-TR is designed with an advanced metal oxide varistor (MOV) technology. This allows it to withstand high voltage and current surges without any damage to the connected components. The device can handle an ESD pulse of up to 5 kV and an EFT pulse of up to 25 amps.

The SMA6J100CA-TR has three modes of operation. In normal operation, it acts as a low impedance path that allows small signal pulses to pass through. In overvoltage and overcurrent conditions, it acts as an open circuit, preventing the pulse from reaching the connected components.

In the third mode, the SMA6J100CA-TR can act as a short circuit, providing an alternate and highly resistant path for the surge to take. This prevents the surge to even reach the input power source or the connected components, further increasing the device\'s effectiveness.

Conclusion

The SMA6J100CA-TR is an effective surge protection device for mobile phones and other devices with USB charger connections. The metal oxide varistor technology allows it to withstand ESD and EFT pulses of high voltage and current. It also has three modes of operation that provide an effective and highly resistant protective layer against such surges.
