State-of-the-art geometry features epitaxial construction with oxide passivation and metal overlay contact. Ideally suited for low voltage, high frequency rectification, or as free wheeling and polarity protection diodes, in surface mount applications where compact size and weight are critical to the system. 4.65 ± 0.30 5.30 ± 0.22 1.14 ± 0.38 0.1 ± 0.1 0.22 ± 0.07 2.1 ± 0.15 2.28 ± 0.15 3.62 ± 0.32 FEATURES : * * * * * Very Low Forward Voltage Drop Small Compact Surface Mountable Package Highly Stable Oxide Passivated Junction Guardring for Stress Protection Pb / RoHS Free Dimensions in millimeters MECHANICAL DATA : * * * * * * Case : SMB Molded plastic Epoxy : UL94V-O rate flame retardant Lead : Lead Formed for Surface Mount Polarity : Color band denotes cathode end Mounting position : Any Weight : 0.1079 gram MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS Rating at 25 °C ambient temperature unless otherwise specified.
