Overview
The Fairchild Semiconductor 1N486B-T50A is a standard silicon rectifier diode housed in the DO-35 glass axial leaded package. It features a maximum DC reverse voltage of 250 V and an average forward rectified current of 200 mA. The device supports a peak surge current of up to 4 A under specified conditions. It operates within a temperature range of -65°C to +200°C, with power dissipation rated at 500 mW at 75°C ambient temperature.
Feature Summary
- Utilizes standard silicon technology for reliable rectification
- Encapsulated in a compact DO-35 glass axial package
- Capable of handling high peak surge currents
Applications
- General purpose rectification in electronic circuits
- Power supply input stages
- Signal demodulation applications
Procurement Notes
Verify component status as this part may be obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors only. Ensure the DO-35 package matches your PCB footprint requirements. Check for RoHS compliance if required by your assembly standards. Validate that the 250V rating meets your circuit's peak inverse voltage needs.
Selection Notes
Select this component when a 250V reverse voltage rating and 200mA continuous current are sufficient for the application. The DO-35 package is suitable for through-hole mounting. Consider thermal derating above 75°C ambient temperature. Compare against other 1N4xxx series diodes if alternative voltages or currents are needed. Ensure the operating temperature range covers your environmental conditions.
Part Context
This component belongs to the 1N4xxx series of small signal rectifier diodes manufactured by Fairchild Semiconductor (now onsemi). These diodes are widely used in general-purpose electronics for converting AC to DC. The 1N486B variant specifically provides a 250V blocking capability. The T50A suffix typically denotes tape and reel packaging for automated assembly.
Replacement Considerations
Public confirmed substitute part numbers include the 1N486B from various manufacturers. Verify pinout compatibility and electrical ratings before substitution. Ensure the replacement diode supports the same DO-35 package style.
