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 requested quantity aligns with the minimum order quantities specified for tape and reel or ammo pack formats.

Single Zener Diodes Selection Notes

Select this component when a precise 68 V reference is required in a through-hole configuration. Consider the positive temperature coefficient for applications where voltage stability across varying temperatures is critical. Evaluate the 500 mW power dissipation limit relative to the expected circuit load and ambient 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 voltage range from 2.4 V to 75 V, offering various tolerance options including ±5% and ±2%. These diodes are designed for general-purpose voltage regulation tasks in electronic equipment.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 68 V Zener diodes in the DO-35 package. Verify that substitute components match the 500 mW power rating, ±5% tolerance, and electrical characteristics such as dynamic resistance and leakage current.
