SMV1245 Series Absolute Maximum Ratings (Note 1) Parameter Symbol Minimum Maximum Units 250 mW Power dissipation PDIS Forward current IF 20 mA Operating temperature TOP –55 +125 C Storage temperature TSTG –55 +150 C Electrostatic discharge: ESD < 250 V Human Body Model (HBM), Class 0 Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although these devices are designed to be as robust as possible, electrostatic discharge (ESD) can damage them. These devices must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
