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.
