ESD112B102ELSE6327XTSA1 Circuit Protection

TVS (transient voltage suppressor) diodes, such as the ESD112B102ELSE6327XTSA1, are used to protect sensitive electronics from destructive electrostatic discharges and high voltage transients. The ESD112B102ELSE6327XTSA1 is a unidirectional diode that can handle up to a 12 V peak voltage. Its application field and working principle are as follows.

Application Field

ESD112B102ELSE6327XTSA1 is designed to be used in electronic circuits to protect them from damage due to over-voltage, usually from electrostatic discharges (ESD). It is suitable for use in automotive, consumer electronics, medical, industrial, and communication applications.

Working Principle

When an excessive voltage is applied to the ESD112B102ELSE6327XTSA1, it will immediately start conducting current. This is because the voltage applied to exceeds its rated “breakdown” voltage. As this happens, the ESD112B102ELSE6327XTSA1 acts as a surge absorber, drawing up the excessive current in order to protect the circuitry it is hooked up to. The semiconductor junction at the heart of the device undergoes a process akin to avalanche breakdown, and in essence allows the surge current to be dissipated.

The ESD112B102ELSE6327XTSA1 can handle only relatively short high voltage transients – it is not designed to handle sustained high voltage applications. It is also not suitable as the sole means of protection against over-voltage, as it is not designed to handle high current surges.

Conclusion

The ESD112B102ELSE6327XTSA1 is a unidirectional diode designed to protect sensitive electronic components from electrostatic discharges and high voltage transients. It is suitable for use in automotive, consumer electronics, medical, industrial, and communication applications. When an excessive voltage is applied to the device, it conducts current, drawing up the excessive current in order to protect the circuitry it is hooked up to.
