Preferred Device

Axial Lead Rectifier

This device employs the Schottky Barrier principle in a large area

metal−to−silicon power diode. State−of−the−art geometry features

epitaxial construction with oxide passivation and metal overlap

contact. Ideally suited for use as rectifiers in low−voltage,

high−frequency inverters, free wheeling diodes, and polarity

protection diodes.

Features

•Extremely Low VF

•Low Power Loss/High Efficiency

•Highly Stable Oxide Passivated Junction

•Low Stored Charge, Majority Carrier Conduction

•Pb−Free Packages are Available*

Mechanical Characteristics:

•Case: Epoxy, Molded

•Weight: 1.1 Gram (Approximately)

•Finish: All External Surfaces Corrosion Resistant and Terminal

Leads are Readily Solderable

•Lead Temperature for Soldering Purposes:

260°C Max. for 10 Seconds

•Polarity: Cathode indicated by Polarity Band

Stresses exceeding Maximum Ratings may damage the device. Maximum

Ratings are stress ratings only. Functional operation above the Recommended

Operating Conditions is not implied. Extended exposure to stresses above the

Recommended Operating Conditions may affect device reliability.

1. Lead Temperature reference is cathode lead 1/32 in from case.

2. The heat generated must be less than the thermal conductivity from

Junction−to−Ambient: dPD/dTJ < 1/RqJA.
