7.3 Off-Leakage Current

Source and drain off-leakage current is defined as the leakage current flowing into or out of the source or drain

pin when the switch is off. This current is denoted by the symbol IS(OFF) and ID(OFF). Figure 7-3 shows the setup

used to measure off-leakage current.

7.4 Power-Off Leakage Current

Powered-off source and drain leakage current is defined as the leakage current flowing into or out of the source

or drain pin when the device is powered off. This current is denoted by the symbol IPS(OFF) and IPD(OFF). Figure

7-4 shows the setup used to measure off-leakage current.
