Single Zener Diodes Procurement Notes

Verify the specific suffix _T50R against official datasheets to confirm packaging details such as reel or cut tape specifications. Ensure compatibility with existing board layouts regarding the DO-35 footprint dimensions. Confirm that the operating environment remains within the specified thermal limits to maintain performance integrity.

Single Zener Diodes Selection Notes

Select this component when a standard 30 V regulation point is required in through-hole designs. The DO-35 package offers robust mechanical stability compared to surface-mount alternatives. Consider the 500 mW power rating to ensure adequate thermal headroom under continuous load conditions without exceeding junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of general-purpose Zener diodes manufactured by onsemi. The series utilizes silicon planar technology to deliver consistent breakdown characteristics. The 1N5256B variant specifically targets the 30 V segment, offering a balance between low leakage and stable impedance for precision analog applications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5256B equivalents ensuring identical DO-35 packaging and 30 V nominal voltage. Verify that substitute parts meet the same 500 mW power dissipation and ±5% tolerance requirements to maintain circuit functionality.
