Overview
The onsemi 1N5408RLG is a glass-passivated standard recovery rectifier in an axial-lead DO-201AD (Case 267-05) package. It features a maximum average forward current of 3.0 A and a peak repetitive reverse voltage of 1000 V. The device supports a non-repetitive peak surge current of 200 A for one cycle. Electrical characteristics include a maximum forward voltage of 1.0 V at 3.0 A and a junction-to-ambient thermal resistance of 53 °C/W. Operating temperatures range from -65°C to +150°C.
Feature Summary
- High surge current capability
- Low forward voltage drop
- Void-free economical plastic package
Applications
- Power supplies
- General purpose rectification
Procurement Notes
Verify the specific ordering suffix 'RLG' corresponds to tape and reel packaging containing 1200 units per reel, distinct from the box-packaged 'G' variant. Confirm compliance with UL 94 V-0 flammability standards and Pb-Free status as documented in the manufacturer's datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a 1000 V blocking voltage and 3 A continuous current rating are required in an axial lead format. Ensure the application environment remains within the specified -65°C to +150°C junction temperature range. Consider the 53 °C/W thermal resistance for heat dissipation planning in still air conditions.
Part Context
This part belongs to the 1N540x series of axial-lead standard recovery rectifiers manufactured by onsemi. The series covers reverse voltages from 50 V to 1000 V, sharing identical mechanical dimensions and current ratings while differing only in breakdown voltage specifications.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N5408 diodes meeting the same electrical and mechanical specifications. Verify pinout polarity and package dimensions match Case 267-05 requirements.
FAQ
What is the maximum forward voltage drop?
The maximum forward voltage is 1.0 V at an forward current of 3.0 A.
Is the device lead-free?
Yes, the datasheet confirms these are Pb-Free devices.
