represent statistically the utmost probability at following conditions: V
IN
=24V, V
OUT
=12V, R
ON
=249KΩ T

NOTES
(1) The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test
method is per JESD-22-114.
(2) JEDEC J-STD020
(3) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are
guaranteed through correlation using Statistical Quality Control (SQC) methods.
(4) Typical numbers are valid at 25°C ambient temperature and represent statistically the utmost probability
assuming the Gaussian distribution.
(5) Depending on heat sink design, number of PCB layers, copper thickness and air flow.
(6) 4 layer printed circuit board, 76.2mm x 76.2mm area, 35µm copper, no air flow.
