Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation, noting that some variants may not meet standard restrictions. Ensure the D-5B-2 footprint matches your PCB design requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 36 V regulation point is required alongside high thermal endurance. The 5 W power rating allows for robust performance in high-current scenarios compared to lower-wattage alternatives. Consider the extended temperature range suitability for aerospace or industrial deployments where standard commercial parts would fail.

Single Zener Diodes Part Context

This part belongs to the 1N49xx series of Zener diodes manufactured by Microchip Technology. The US designation typically denotes a specific hermetic or ruggedized construction style often used in defense and aerospace sectors. The /TR suffix specifically identifies the reel packaging format for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N4971US or JANTX1N4971US for equivalent electrical specifications. Verify package compatibility between axial and surface-mount variants if cross-referencing with through-hole versions like the standard 1N4971.
