SG137A/SG137 SERIES
ABSOLUTE MAXIMUM RATINGS (Note 1)
Power Dissipation .........................................I.nternally Limited
Input to Output Voltage Differential ...................................4. 0V
Storage Temperature Range ............................-65°C to 150°C
Note 1. Exceeding these ratings could cause damage to the device.
THERMAL DATA
K Package:
Thermal Resistance-Junction to Leads, θJC ................ 3.0°C/W
Thermal Resistance-Junction to Ambient, θJA ............... 35°C/W
R Package:
Thermal Resistance-Junction to Leads, θJC ................ 5.0°C/W
Thermal Resistance-Junction to Ambient, θJA .............. 40°C/W
T Package:
Thermal Resistance-Junction to Leads, θJC ................. 15°C/W
Thermal Resistance-Junction to Ambient, θJA ............ 120°C/W
IG Package:
Thermal Resistance-Junction to Leads, θJC ................ 3.5°C/W
Thermal Resistance-Junction to Ambient, θJA .............. 42°C/W
L Package:
Thermal Resistance-Junction to Leads, θJC ................. 35°C/W
Thermal Resistance-Junction to Ambient, θJA ............ 120°C/W
Operating Junction Temperature
Hermetic (K, R, T, L, IG-Packages) ........................... 150°C
Lead Temperature (Soldering, 10 Seconds) ............. 300°C
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.
RECOMMENDED OPERATING CONDITIONS (Note 2 & 3)
Input Voltage Range ..............................-(VOUT + 3.5V) to -36V
Operating Junction Temperature Range
SG137A/SG137 ...........................................-.55°C to 150°C
SG237A/SG237 ...........................................-.25°C to 150°C
SG337A/SG337 ............................................. 0°C to 125°C
Note 2. Range over which the device is functional.
Note 3. These ratings are applicable for junction temperatures of less than 135°C.

= 100mA (T and L packages). Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2Ω for the T and
L packages, and 20Ω for the K, R, and IG packages. IMAX is 1.5A for the K, R, and IG packages and 0.5A for the T and L packages. Low duty cycle pulse
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
