The onsemi 1N5406RLG is a standard recovery rectifier diode designed for general-purpose applications. It features a 600 V peak repetitive reverse voltage and supports an average forward current of 3.0 A under specified resistive load conditions. The device is housed in a lead-mounted DO-201AD (Case 267-05) axial package with molded epoxy construction. Key electrical characteristics include a maximum forward voltage drop of 1.0 V at 3.0 A and a non-repetitive peak surge current capability of 200 A. It operates within a junction temperature range of -65°C to +150°C.
Verify the specific ordering suffix 'RLG' confirms tape and reel packaging, distinct from bulk box quantities. Confirm compliance with UL 94 V-0 flammability standards and Pb-Free status as indicated by the datasheet. Ensure the component meets MIL-S-19500/228 environmental standards if required for the application.
Select this component when a 600 V blocking voltage is required alongside a 3 A continuous current rating. Consider the thermal resistance of 53 °C/W for PCB mounting when designing heat dissipation. Verify that the 1.0 V forward voltage drop aligns with system efficiency targets compared to Schottky alternatives.
This part belongs to the 1N5400 through 1N5408 series of axial-lead glass passivated standard recovery rectifiers manufactured by onsemi. The series covers reverse voltages from 50 V to 1000 V while maintaining a consistent 3.0 A average forward current rating across all variants.
Compatible substitutes include Vishay 1N5406-E3/58 and 1N5406GP-E3/54, which share identical 3 A / 600 V ratings and DO-201AD packages.
