Definition
Stand Off Voltage: Maximum dc voltage that can be applied over the operating temperature range.
VWM must be selected to be equal or be greater than the operating voltage of the line to be protected.
Minimum Breakdown Voltage: Minimum voltage the device will exhibit at a specified current
Clamping Voltage: Maximum clamping voltage across the TVS device when subjected to a given current at a
pulse time of 20 µs.
Standby Current: Leakage current at VWM.
Capacitance: Capacitance of the TVS as defined @ 0 volts at a frequency of 1 MHz and stated in picofarads.
