Notes
a. Refer to PROCESS OPTION FLOWCHART for additional information.
b. Room = 25°C, Cold and Hot = as determined by the operating temperature suffix.
c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
d. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
e. Guaranteed by design, not subject to production test.
f. C_STRAY Pin 8 = ≤ 5 pF
g. Temperature coefficient of r_DS(on) is 0.75% per °C, typical.
