1. Pdiss is calculated with Tamb = +25° C, Tj = +150° C and
Rthja = 200° C/W for TO-92 package
Rthja = 130° C/W for SO-8 batwing package
2. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
3. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
4. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
