Parameter Definitions for ESD Devices
Operation Voltage (V
DC
)
Defined as DC voltage, under which device is in OFF state and leakage current below certain threshold.
Leakage Current (I
L
)
Current through device under Operation Voltage V
DC
.
Trigger Voltage (V
T
)
Voltage at which the device switches from the OFF to the ON state, during the IEC waveform or the TLP system.
Clamping Voltage (V
C
)
Voltage cross device under 8 kV per IEC or measured by TLP system. Typically measured 30 ns after initiation of the ESD pulse
(for TLP both 30ns and 60ns are sometimes used).
,
Capacitance (C
P
)
Capacitance of the device measured at 1 MHz with 0V and max operating voltage bias.
