Preferred Devices

Surface Mount
Schottky Power Rectifier

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
