THERMAL DATA
RoHS Peak Package Solder Reflow (40 sec. max. exp.)...260°C (+0, -5)
J Package:
Thermal Resistance-Junction to Case, θJC .................. 25°C/W
Thermal Resistance-Junction to Ambient, θJA .............. 70°C/W
N Package:
Thermal Resistance-Junction to Case, θJC .................. 30°C/W
Thermal Resistance-Junction to Ambient, θJA ............. 60°C/W
DW Package:
Thermal Resistance-Junction to Case, θJC .................. 35°C/W
Thermal Resistance-Junction to Ambient, θJA ............. 90°C/W
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.

Note 3: Range over which the device is functional.
Note 4. Larger value capacitor may be used with peak current limiting. See Figure 1.
ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1544 with -55°C ≤ TA ≤ 125°C, SG2544 with
-25°C ≤ TA ≤ 85°C, SG3544 with 0°C ≤ TA ≤ 70°C, and +VIN = 10V. Indicator outputs have 2kΩ pull-up resistors. All electrical ratings and specifications
are tested with the inverting over-voltage input and the non-inverting under-voltage input externally connected to the 2.5V reference. Low duty cycle
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
