THERMAL DATA
Note A. Junction Temperature Calculation: T
J = TA + (PD x θJA).
Note B. The above numbers for
θ
JC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The
θ
JA numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.

RECOMMENDED OPERATING CONDITIONS (Notes 2 & 3)
ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG55451B/461/471 with -55
°C ≤ T
A ≤ 125 °C, and
SG75451B/461/471 with 0
°C ≤ T
A ≤ 70 °C.
Typical values are tested at V
CC = 5V, and T A = 25°C.
Low duty cycle pulse testing techniques are used
which maintains junction and case temperatures equal to the ambient temperature.)
