Application

Posted in MLE Series

  • IC, FET, diode, transistor, thyristor, semiconductor, and the other electronics components protection
  • Suppressing the electronic circuit overvoltage and transient voltage
  • Use for ESD protection for I/O interface circuits
  • Consumer and industrial electronics components input ports for ESD protection

Parameters

Posted in MLE Series

Max working voltage:
When the maximum operating voltage is allowed to use the maximum voltage.
Leakage Current:
The max. working voltage is the allowable max. operating voltage. Leakage current: At normal working condition of devices, the tiny current through body is only about a few μA generally. The so-called normal working condition means the device under normal operating voltage (Working Voltage), that is, when the device in the pre-breakdown situation, the impedance value is extremely large considered as an insulator, so only a tiny current flows.
Max Clamping Voltage:
the maximum clamping voltage is measured at a specific current and the specific current is often used the maximum surge current value at 10,000 times.
Capacitance value:
the measurement at 1MHz condition.

Operation Theory

Posted in MLE Series

The voltage and current of the device is a special non-linear relationship. When the applied voltage cross at both ends is lower than the standard rated voltage, the resistance of device is close to infinity and there is almost no current through internal. When the applied voltage cross at both ends is higher than the normal rated voltage, the device will rapidly breakdown, becomes a low resistance situation from a high impedance situation, and the operating current increases rapidly. When the voltage at both ends is lower than standard rated voltage, the device can recover to high impedance. Therefore, the operating mode is an Off-on-to Off.
