Single Diodes Procurement Notes

Verify the manufacturer source carefully as multiple entities including GeneSiC and Navitas have listed this part number. Confirm whether the unit is new old stock or from an authorized distributor. Check for obsolescence notices, as some sources indicate scheduled discontinuation. Ensure the specific revision matches your design requirements before ordering.

Single Diodes Selection Notes

Select this component when military qualification under MIL-PRF-19500/260 is mandatory. It is suitable for designs requiring 200V blocking capability and 12A continuous current handling. Consider the DO-5 chassis mount form factor for thermal dissipation needs. Verify that the glass-to-metal seal construction meets environmental sealing requirements for your specific application.

Single Diodes Part Context

This part belongs to the 1N series of military silicon power rectifiers. It is distinct from standard commercial diodes due to its rigorous manufacturing controls and material composition. The AR suffix typically denotes a specific case style or processing variant within the military specification framework.

Single Diodes Replacement Considerations

Direct substitutes must meet MIL-PRF-19500/260 standards. Equivalent parts include other 1N1202 variants from qualified manufacturers. Verify pinout compatibility and thermal resistance characteristics before substitution.
