Silicon Rectifiers 1N3208,R IN3214,R A40FM A4IFM General Electric has designed this 20 Ampere rectifier specifically for the normal industrial and consumer low ambient temperature applications. The design utilizers the smallest practical size for the rating with particular attention to rigidity and rugged construction. The solid one-piece terminal and the case-to-hex solder mounting technique provides good mechanical strength, minimizes breakage problems, and pro- motes stability of heat transfer characteristics from the diffused junction to the stud. High Surge Current Capabilities (Up to 300 Amperes) One-piece Terminal Positive Solder Case-to-hex Mounting Small Size 9/16 Hex, 1/2 Diameter Barrel Reverse Polarity Devices Available eoesoese Max, Peak Reverse Voltage Max.
