1N5408 Rectifier Diode with 5uA Peak Reverse Current having Electrical Current Flow in Only One Direction, used for Power Supply Operation. When an alternating Waveform is Applied to a Diode, then it Will only Allow Conduction Over Half the Waveform. The remaining half is blocked. Rectifier Diodes can Handle Higher Current Flow Than Regular Ones, are Widely Used for Dental Science, Blood Analysis, Cancer Detection, DNA Analysis, Cellular Phones, TV Chassis, Motherboards, Clamping Circuits, Switching Applications, Power Supplies, Camcorders, Oscillators. Specifications:- Type: Rectifier Size: 9.5mm Length, 5.3mm Diameter Voltage Rating: 1000V Current Rating: 3A Temperature Rating: -50 to 150 Deg C Number of Pins: 2 Pins Mounting: Through Hole Diode Configuration: Stud Cathode Maximum Forward Voltage Drop: 12V Peak Reverse Current: 5uA Peak Non-Repetitive Forward Surge Current: 200A
