PRODUCTION DATA SHEET
A B S O L U T E M A X I M U M R AT I N G S (Note 1)
Cathode to Anode Voltage (V ) ................................................................. -0.3V to +20V
KA
Reference Input Current (IREF) .................................................................... -50µA to 10µA
Continuous Cathode Current (I ) ............................................................. -25mA to 25mA
K
Operating Junction Temperature
Plastic (SC, SE & LP Packages) ............................................................................. 150°C
Storage Temperature Range ...................................................................... -65°C to 150°C
Lead Temperature ..................................................................................................... 300°C
Note 1. Exceeding these ratings could cause damage to the device. All voltages are with respect
to Ground. Currents are positive into, negative out of the specified terminal. Pin
numbers refer to DIL packages only.
THERMAL DATA
SC PACKAGE:
Thermal Resistance - Junction to Ambient, θJA (PC-Mounted)
(Non-PC Mounted)
220°C/W
410°C/W
SE PACKAGE:
Thermal Resistance - Junction to Ambient, θJA (PC-Mounted)
(Non-PC Mounted)
220°C/W
410°C/W
LP PACKAGE:
Thermal Resistance-Junction to Ambient, θJA
156°C/W
Junction Temperature Calculation: TJ = TA + (PD x θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board system.
All of the above assume no ambient airflow
