TVS (transient voltage suppressor) diodes, also known as ESD (electrostatic discharge) suppressors, are designed to provide surge protection from electrical transients that are caused by sources of electromagnetic interference (EMI) such as lightning, Electrostatic Discharge (ESD) events, etc. in the environment. 1.5KE6.8AHE3_A/D (unidirectional) is a typical TVS protection diode.

1.5KE6.8AHE3_A/D application field mainly applies to electronics, telecommunications, consumer products, automobiles, and many other industrial fields and equipment, all of which are prone to electrostatic and surge transient effects.

1.5KE6.8AHE3_A/D works as follows: when a static electricity or surge transient current over the designed peak or peak reverse voltage (PRV) is applied to the diode\'s cathode, it forms an avalanche breakdown by changing the reverse voltage of diode into a very low impedance path (resistance value is very small) which brings up the current so that it can be used to discharge the protective diode and effectively protect the circuit.(The forward breakover voltage of 1.5KE6.8AHE3_A/D is usually 5.6V to 6.8V).

When an overvoltage pulse is released, 1.5KE6.8AHE3_A/D will attach to the electrical device and keep the device intact. It has a fast response time (typically between 10 nanoseconds and 1 microsecond). It will automatically reset itself and recover after the overvoltage pulse has subsided.

1.5KE6.8AHE3_A/D has mainly 3 characteristics：high withstand voltage and wide working temperature range, it can even work properly in harsh environment and high humidity; second is very low leakage current, that\'s to say, it can discharge more current but with a small current still flows through the diode; third is low capacitance, which can reduce the positive feedback, thus limiting the flyback voltage.

1.5KE6.8AHE3_A/D is a very important component when it comes to providing protection from overvoltage. Since it can act quickly to protect the component from overvoltage, it is a great component to use for ESD protection, surge protection, and overvoltage protection.

To summarize, 1.5KE6.8AHE3_A/D is designed to provide robust protection against electrostatic discharge events and transient voltage surges for a wide range of electronic systems and applications. With its excellent characteristics of high withstand voltage, wide working temperature, low leakage current, and low capacitance, 1.5KE6.8AHE3_A/D can effectively respond to overvoltage pulses and reset itself to protect the circuit.
