Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging if required by automated assembly processes. Confirm RoHS compliance status as sources indicate non-RoHS variants exist for this part number. Ensure the DO-35 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 19.2 V reference with low temperature drift is necessary. The DO-35 package suits manual or wave soldering workflows. Consider the 500 mW power rating to ensure adequate thermal headroom in the intended circuit environment without requiring additional heat sinking measures.

Single Zener Diodes Part Context

This part belongs to Microchip's discrete semiconductor diode portfolio, specifically the Zener diode category. It serves as a fundamental passive component for voltage regulation and protection tasks. The 1N4926 designation follows standard industry naming conventions for Zener devices, while the /TR suffix denotes specific packaging format.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4926 equivalents. Verify that replacement parts maintain the 19.2 V nominal voltage and ±5% tolerance. Ensure the alternative component supports the same DO-35 package and 500 mW power dissipation rating for mechanical and electrical compatibility.
