Surface Mount

Schottky Power Rectifier

SOD–123 Power Surface Mount 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 a 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

•Epoxy Meets UL94, VO at 1/8″

•Package Designed for Optimal Automated Board Assembly

Mechanical Characteristics:

•Reel Options: 3,000 per 7 inch reel/8 mm tape

•Reel Options: 10,000 per 13 inch reel/8 mm tape

•Device Marking: B4

•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

* Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any re-

verse voltage conditions. Calculations of TJ therefore must include forward and reverse power effects. The allowable operating

TJ may be calculated from the equation: TJ = TJmax – r(t)(Pf + Pr) where

r(t) = thermal impedance under given conditions,

Pf = forward power dissipation, and

Pr = reverse power dissipation

This graph displays the derated allowable TJ due to reverse bias under DC conditions only and is calculated as T J = TJmax – r(t)Pr,

where r(t) = Rthja. For other power applications further calculations must be performed.
