Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compliance with required electrical tolerances and thermal ratings. Confirm that the DO-35 axial package aligns with the target PCB layout constraints. Cross-reference datasheet parameters such as dynamic impedance and leakage current against design specifications before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a 68 V Zener voltage is required in an axial through-hole configuration. Consider the 500 mW power rating and thermal resistance characteristics for heat management. Ensure the operating environment stays within the specified -65°C to +175°C temperature range for reliable performance.

Single Zener Diodes Part Context

This component belongs to the 1N5221B-G through 1N5267B-G series of axial leaded glass Zener diodes manufactured by Comchip Technology. The series covers a wide voltage range from 2.4 V to 75 V, all sharing the same 500 mW power dissipation capability and DO-35 mechanical housing.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5266B equivalents or 1N5266 variants, provided they match the 68 V nominal voltage, 500 mW power rating, and DO-35 axial package dimensions.
