THERMAL DATA
Note A. Junction Temperature Calculation: T
= T
+ (P
x
θ
).
Note B. The above numbers for
θ
are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The
θ
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
(Note 2)
ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1503 with -55°C
≤
T
≤
125°C, SG2503/SG3503
with 0°C
≤
T
≤
70°C, V
= 15V, and I
L
= 0mA. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal
to the ambient temperature.)
