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 mounting 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 (Note 2)
ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specfiications apply over the operating ambient temperatures for SG1731 with -55
°C ≤ T
A ≤ 125°C, SG2731 with
-25
°C ≤ T
A ≤ 85°C, SG3731 with 0°C ≤ TA ≤ 70°C, VS = ±15V, and VO = ±22V. Low duty cycle pulse testing techniques are used which maintains junction
and case temperatures equal to the ambient temperature.)
