Schottky barrier rectifier provides 40 V repetitive peak reverse voltage and 1.0 A average forward rectified current. The axial DO-41 package uses molded plastic construction with a cathode band polarity mark. Low forward voltage is rated up to 0.60 V at 1.0 A and 0.90 V at 3.1 A for the 1N5819 rating. The device supports a 25 A non-repetitive surge current and operates over a -65 °C to +125 °C junction temperature range.
