ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
abovethoseindicatedintheoperationalsectionsofthisspecificationisnot
implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
Reverse Current (IKA) ............................................................. 30mA
Forward Current (IAK) ............................................................. 10mA
Operating Temperature Range (TA) ............................ -40 to +85°C
Junction Temperature (TJ) ..................................................... 150°C
Storage Temperature (TSTG) ....................................... - 65 to 150°C
Lead Temperature (Soldering 10 sec.), TL ............................. 300°C
ELECTRICAL CHARACTERISTICS
IIN = 100µA, TA = 25°C, unless otherwise specified. The ♦ denotes the specifications which apply over the full operating
temperature range, unless otherwise specified.
