Absolute Maximum Ratings Stress greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These stress ratings only, and functional operation of the devic e at these or any conditions beyond those indicated under recommended Operating Conditions is not implied. Exposure to “Absolute Maximum Rating” for extended periods may affect device reliab ility. Use of standard ESD handling precautions is required. Parameter Value Units ANODE Forward Current +50 mA ANODE Reverse Current -50 mA Operating Junction Temperature 150 ºC Lead Temperature (soldering 10 seconds) 260 ºC Storage Temperature Range -65 to +150 ºC ESD (Human Body Model) 2 KV Electrical Specifications Electrical characteristics are guaranteed at 25ºC unless otherwise stated. Ambient temperature must be de-rated based upon power dissipation and package thermal characteristics.
