Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm shipping format. Standard bulk bags contain 5000 units, while tape and reel options are available for automated assembly. Confirm RoHS compliance status directly with the manufacturer before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 16 V reference is required within a through-hole design. Ensure the circuit can accommodate the 7.8 mA test current and that thermal derating above 50°C is calculated correctly. Verify that the 17 Ohm dynamic impedance meets the noise and stability requirements of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of Zener diodes manufactured by onsemi. The series covers a wide voltage range using standardized axial lead packages. The 1N5246B specifically addresses mid-range voltage stabilization needs within this established product family.

Single Zener Diodes Replacement Considerations

Cross-reference with Vishay Semiconductors 1N5246B or Taiwan Semiconductor 1N5246B R0 for equivalent electrical characteristics. Verify package dimensions and marking codes match the existing board layout before substitution.
