Definitions Operating Voltage Range (V SUPPLY ; SP72x Series only) The range limits of the power supply voltage that may be across the V+ and V- terminals. The SCR/Diode arrays do not have a fixed breakover or operating voltage. These devices 'float' between the input and power supply rails and thus the same device can operate at any potential within its range. Forward Voltage Drop (SP72x Series only) The maximum forward voltage drop between an input pin and respective power supply pin for a specific forward current. Reverse Voltage Drop or Breakdown Voltage The voltage at which an input pin will begin to conduct current to the respective power pin. This parameter is usually stated at a specific reverse current. Reverse Standoff Voltage or Reverse Working Maximum The device V R or V RWM should be equal to or greater than the peak operating voltage of circuit (or part of the circuit) to be protected. This is to ensure that the TVS Diode Array does not clip the signal voltage. Reverse Leakage Current Maximum leakage current the protection device conducts in the off-state measured at specified voltage. Clamping Voltage Maximum voltage which can be measured across the protector when subjected to the stated peak pulse current. The "I PP " or Peak Pulse Current is typically an 8x20 s waveform that aims to reduce voltage spikes or overshoots due to parasitic PCB inductance. Input Leakage Current (SP72x Series only) The DC current that is measured at the input pins at the stated voltage supplied to the input. Quiescent Supply Current (SP72x Series only) The maximum DC current into V+ and V- pins with V SUPPLY at its maximum voltage. Capacitance The capacitance measured between the input pin and a reference (usually GND) with a 1MHz, 30 mV RMS signal. Definitions and Terms
