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.

Features

•These are Pb−Free Devices*

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

•Available Tape and Reel, 1200 per Reel, by adding a “RL” Suffix

to the Part Number
