Surface Mount
Schottky Power Rectifier
SMB Power Surface Mount Package
This device employs the Schottky Barrier principle in a
metal−to−silicon power rectifier. Features epitaxial construction with
oxide passivation and metal overlay contact. Ideally suited for low
voltage, high frequency switching power supplies; free wheeling
diodes and polarity protection diodes.
Features
• Compact Package with J−Bend Leads Ideal for Automated Handling
• Highly Stable Oxide Passivated Junction
• Guardring for Over−Voltage Protection
• Low Forward Voltage Drop
• Pb−Free Package is Available
Mechanical Characteristics:
• Case: Molded Epoxy
• Epoxy Meets UL 94 V−0 @ 0.125 in
• Weight: 95 mg (Approximately)
• Cathode Polarity Band
• Lead and Mounting Surface Temperature for Soldering Purposes:
260°C Max. for 10 Seconds
• Finish: All External Surfaces Corrosion Resistant and Terminal
Leads are Readily Solderable
