Electrical Characteristics
Limits in standard typeface are for T
J = 25˚C, and limits in boldface type apply over the −40˚C to +125˚C operating temperature
range. Limits are guaranteed by production testing or correlation techniques using standard Statistical Quality Control (SQC)
methods. (Continued)

Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de-
vice outside of its rated operating conditions.
Note 2: The typical thermal resistance of the three package types is:
T (TO-220) package:
θ(JA) = 60 ˚C/W, θ(JC) = 5 ˚C/W
H (TO-39) package:
θ(JA) = 120 ˚C/W, θ(JC) = 18 ˚C/W
DT (TO-252) package:
θ(JA) = 92 ˚C/W, θ(JC) = 10 ˚C/W
