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

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1846/SG1847 with -55°C≤ TA ≤ 125°C, SG2846
with -25°C ≤ TA ≤ 85°C, SG3846 with 0°C ≤ T ≤ 70°C, +VIN = 15V. Low duty cycle pulse testing techniques are used which maintains junction and
case temperatures equal to the ambient tempAerature.)
