Schottky Power Rectifier
MBRA140T3
SMA Power Surface Mount Package
. . . employing the Schottky Barrier principle in a large area metal–to–silicon
power diode. 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 diodes in surface mount
applications where compact size and weight are critical to the system.
• Small Compact Surface Mountable Package with J–Bent Leads
• Rectangular Package for Automated Handling
• Highly Stable Oxide Passivated Junction
• Very Low Forward Voltage Drop
• Guardring for Stress Protection
Mechanical Characteristics:
• Case: Epoxy, Molded
• Weight: 70 mg (approximately)
• Finish: All External Surfaces Corrosion Resistant and Terminal Leads are
Readily Solderable
• Lead and Mounting Surface Temperature for Soldering Purposes:
260°C Max. for 10 Seconds
• Shipped in 12 mm tape, 5000 units per 13 inch reel
• Polarity: Notch in Plastic Body Indicates Cathode Lead
• Marking: B4
