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″
•Guaranteed Reverse Avalanche
•Compact Size
•Lead Formed for Surface Mount
Mechanical Characteristics
•Case: Epoxy, Molded
•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
