Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details. Confirm that the component meets RoHS3 compliance requirements for your region. Ensure the selected variant matches the required tolerance class and package type before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 20 V reference is required within a through-hole design. Consider the positive temperature coefficient for thermal compensation needs. Evaluate the dynamic resistance and leakage specifications against circuit sensitivity requirements to ensure adequate performance under varying load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 'B' suffix indicates the standard ±5% tolerance grade available in the axial DO-35 package configuration.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 20 V Zener diodes in the DO-35 package. Verify that substitute parts match the 500 mW power dissipation rating and the ±5% voltage tolerance specification to maintain circuit integrity.
