PRODUCTION DATA SHEET
ABSOLUTE MAXIMUM RATINGS
Cathode to Anode Voltage (VKA)(Note 2) ....................................................... -0.3 to 37V
Reference Input Current (IREF).................................................................. -50µA to 10mA
Continuous Cathode Current (IK) .......................................................... -100mA to 150mA
Operating Junction Temperature................................................................................ 150°C
Storage Temperature Range.........................................................................-65°C to 150°C
Package Peak Temp. for Solder Reflow (40 seconds maximum exposure) ... 260°C (+0 -5)
Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to
Ground. Currents are positive into, negative out of specified terminal.
Note 2. Voltage values are with respect to the anode terminal unless otherwise noted.
THERMAL DATA
DM ^{Plastic SOIC 8-Pin}
THERMAL RESISTANCE-JUNCTION TO AMBIENT, θ_JA
165°C/W
PK ^{Plastic TO-89 3-Pin}
THERMAL RESISTANCE-JUNCTION TO AMBIENT, θ_JA
71°C/W
LP ^{Plastic TO-92 3-Pin}
THERMAL RESISTANCE-JUNCTION TO AMBIENT, θ_JA
156°C/W
Junction Temperature Calculation: T_J = T_A + (P_D x θ_JA).
The θ_JA numbers are guidelines for the thermal performance of the device/pc-board system. All of the
above assume no ambient airflow.
