Rectifier Device Data
Plastic SOD–123 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 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 (0.38 V Max @ 0.5 A, 25°C)
•125°C Operating Junction Temperature
•Epoxy Meets UL94, VO at 1/8″
•Package Designed for Optimal Automated Board Assembly
Mechanical Characteristics
•Reel Options: MBR0520LT1 = 3,000 per 7″ reel/8 mm tape.
Reel Options: MBR0520LT3 = 10,000 per 13″ reel/8 mm tape.
•Device Marking: B2
•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
