Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., -TP) against official Micro Commercial Components documentation to confirm packaging type and compliance status. Ensure that the authorized distributor channel is used to guarantee genuine parts with full traceability. Cross-reference the manufacturer part number with the latest datasheet revision to validate all electrical parameters before integration into designs.

Single Zener Diodes Selection Notes

Select this component when a standard 33 V reference is required in an axial through-hole configuration. The 5% tolerance ('B' suffix) suits general-purpose applications where tighter precision is not critical. Consider the positive temperature coefficient for thermal stability requirements in the operating environment.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V, offering various tolerance options including 5% and 2%. These components are designed for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5257B from onsemi or Taiwan Semiconductor, provided they match the DO-35 package and 33 V specification. Verify pinout compatibility and ensure equivalent thermal and electrical ratings are met.
