Axial Lead Fast Recovery Rectifiers
Axial lead mounted fast recovery power rectifiers are designed for special applications such as dc power supplies, inverters, converters, ultrasonic systems, choppers, low RF interference and free wheeling diodes. A complete line of fast recovery rectifiers having typical recovery time of 100 nanoseconds providing high efficiency at frequencies to 250 kHz. Mechanical Characteristics • Case: Epoxy, Molded • Weight: 1.1 gram (approximately) • Finish: All External Surfaces Corrosion Resistant and Terminal Leads are Readily Solderable • Lead and Mounting Surface Temperature for Soldering Purposes: 220°C Max. for 10 Seconds, 1/16″ from case • Shipped in plastic bags, 5,000 per bag. • Available Tape and Reeled, 1500 per reel, by adding a “RL” suffix to the part number • Polarity: Cathode Indicated by Polarity Band • Marking: R850, R851, R852, R854, R856
