SOD–123 Power Surface Mount Package
The Schottky Power Rectifier employs the Schottky Barrier principle with a barrier
metal that produces optimal forward voltage drop–reverse current tradeoff. Ideally
suited for low voltage, high frequency rectification, or as a free wheeling and polarity
protection diodes in surface mount applications where compact size and weight are
critical to the system. This package provides an alternative to the leadless 34 MELF
style package. These state–of–the–art devices have the following features:
• Guardring for Stress Protection
• Very Low Forward Voltage
• Epoxy Meets UL94, VO at 1/8″
• Package Designed for Optimal Automated Board Assembly
Mechanical Characteristics:
• Reel Options: 3,000 per 7 inch reel / 8 mm tape
• Reel Options: 10,000 per 13 inch reel / 8 mm tape
• Device Marking: B4
• Polarity Designator: Cathode Band
• Weight: 11.7 mg (approximately)
• Case: Epoxy Molded
• 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
