THERMAL DATA

Note A.

Junction Temperature Calculation: T

J = TA + (PD x θJA).

Note B. The above numbers for

JC are maximums for the limiting thermal

resistance of the package in a standard mounting configuration.

The

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.)
