Plastic·Packaged, General·Purpose
Types for Low·Power Applications
Feawres:
• Electrically identical to JEDEC types lN4001-1N4007
• High surge-c:urrent capability
• Low junction·to·lead thermal impedances
• -65 to +17s"C oparating temparature range
RCA 01201 seriest devices are diffused·junction type silicon
rectifiers in an axial·lead plastic package. These devices differ
only in their voltage ratings.
Their small size and plastic package of high insulation resis·
tance make these rectifiers especially suited for those appli·
cations in which high packing densities are desirable.
