ABSOLUTE MAXIMUM RATINGS
(Note 1)
Cathode to Anode Voltage (V
KA) (Note 2)
-0.3V to 37V
Continuous Cathode Current (I
K)
-100mA to 150mA
Reference Input Current (I
REF)
-50uA to 10mA
Maximum junction temperature range, TJ
150°C
Storage temperature range
-65
OC to 150OC
Lead temperature (soldiering, 10 seconds)
260°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.
Note 2:
Voltage values are with respect to the anode terminal unless otherwise noted.

Note :
1.
For PK package, Thermal Resistance-Junction to Tab (
θ
JT ) = 35°C /W. TJ = TTAB + (PD × θJT).
P
D: Power Dissipation.

JA: Thermal Resistance-Junction to Ambient,
DF = 1/θ
JA
Junction Temperature Calculation:
T
J = T
A + (PD × θJA).
The
θ
JA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
