Preferred Device
SWITCHMODE
Power Rectifier
DPAK Surface Mount Package
This SWITCHMODE power rectifier which uses the Schottky
Barrier principle with a proprietary barrier metal, is designed for use
as output rectifiers, free wheeling, protection and steering diodes in
switching power supplies, inverters and other inductive switching
circuits. This state of the art device has the following features:
• Low Forward Voltage
• 125°C Operating Junction Temperature
• Epoxy Meets UL94, VO at 1/8″
• Compact Size
• Lead Formed for Surface Mount
Mechanical Characteristics

• Weight: 0.4 gram (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 75 units per plastic tube
• Available in 16 mm Tape and Reel, 2500 units per 13″ reel, by
adding a “T4” suffix to the part number
• Marking: B835L
