SFDS1045Le3 HALOGEN Schottky Barrier Photovoltaic Bypass Diode FREE DESCRIPTION The SFDS1045Le3 is a single Schottky rectifier assembled in a thin flexible package. The device is designed specifically for use as a photovoltaic bypass diode for solar panels. Its low 0.81 mm (0.032 inch) height allows it to be assembled under the glass of the panel, if desired. Customized configurations are available for high volume applications.

LEAD PULL STRENGTH: Min 10 lb/f (44.4 N). A standard (no lead bend) device has one lead secured and the other is pulled outwards along the axis and in the same plane as the device. All devices can meet the minimum value with no damage to the device. LEAD EXTENSION: Max 0.039 inch (1 mm). The leads may need to expand or contract during the solar module assembly process or during normal temperature variations (daytime to nighttime) in standard operation. MARKING: Manufacturer, package type, part number and date code. POLARITY: Cathode lead is notched. DELIVERY option: Blister tray with a base quantity of 80 pieces. WEIGHT: 0.53 grams (approximate).
