7 Parameter Measurement Information

7.1 On-Resistance

The on-resistance of a device is the ohmic resistance between the source (Sx) and drain (D) pins of the device.

The on-resistance varies with input voltage and supply voltage. The symbol RON is used to denote on-resistance.

The measurement setup used to measure RON is shown in Figure 7. Voltage (V) and current (ISD) are measured

using this setup, and RON is computed with RON = V / ISD:

Figure 7. On-Resistance Measurement Setup

7.2 Off-Leakage Current

Source leakage current is defined as the leakage current flowing into or out of the source pin when the switch is

off. This current is denoted by the symbol IS(OFF).

The setup used to measure off-leakage current is shown in Figure 8.
