ABSOLUTE MAXIMUM RATINGS
Cathode-Anode Reverse Breakdown VKZ ....................................... 22V
Anode-Cathode Forward Current, (<10ms) IAK ................................. 1A
Operating Cathode Current IKA .................................................. 120mA
Reference Input Current IREF .......................................................... 1mA
Continuos Power Dissipation at 25°C PD
SOT-23 .................................................................. 200 mW

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS 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 above those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Typical deratings of the thermal resistances are given for ambient
temperature >25°.
ELECTRICAL CHARACTERISTICS
Electrical characteristics are guaranted over the full junction temperature range (0°C to 105°C). Ambient temperature must
be derated based upon power dissipation and package thermal characteristics. Unless otherwise specified, test conditions are:
VKA = VREF and IK = 10mA.
