SMS3925 Series Absolute Maximum Ratings (Note 1) Parameter Symbol Minimum Maximum Units Reverse voltage VR 40 V Forward current IF 50 mA Power dissipation PD 250 mW Storage temperature T 65 +150 C STG Operating temperature TA 65 +150 C Junction temperature T +150 C J Electrostatic discharge: ESD Human Body Model (HBM), Class 0 <250 V 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 this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device 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.
