ABSOLUTE MAXIMUM RATINGS
Cathode to Anode Voltage (VKA)(Note 2) ....................................................... -0.3 to 37V
Reference Input Current (IREF).................................................................. -50A 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.

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.
