Surface Mount
Schottky Power Rectifier
Plastic SOD−123 Package
...using the Schottky Barrier principle with a large area
metal−to−silicon power diode. 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. This package also provides an easy to work
with alternative to leadless 34 package style. Because of its small size,
it is ideal for use in portable and battery powered products such as
cellular and cordless phones, chargers, notebook computers, printers,
PDAs and PCMCIA cards. Typical applications are ac/dc and dc−dc
converters, reverse battery protection, and “Oring” of multiple supply
voltages and any other application where performance and size are
critical. These state−of−the−art devices have the following features:
• Guardring for Stress Protection
• Low Forward Voltage
• 125°C Operating Junction Temperature
• Epoxy Meets UL94, V0 at 1/8″
• Package Designed for Optimal Automated Board Assembly
• ESD Ratings: Machine Model, C
ESD Ratings: Human Body Model, 3B
Mechanical Characteristics
• Reel Options: MBR140SFT1 = 3,000 per 7″ reel/8 mm tape
Reel Options: MBR140SFT3 = 10,000 per 13″ reel/8 mm tape
• Device Marking: L4F
• 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
