Single Zener Diodes Procurement Notes

Verify the specific suffix _T26A against official onsemi documentation to confirm tape and reel packaging details. Ensure compatibility with existing board layouts for DO-35 through-hole components. Check for end-of-life status or alternative sourcing options if availability is constrained. Confirm RoHS compliance requirements match project specifications.

Single Zener Diodes Selection Notes

Select this component when a 30 V Zener voltage with 5% tolerance is required in a DO-35 package. Consider the 500 mW power rating and high-temperature capability for demanding environments. Compare with other manufacturers' 1N5256B equivalents if onsemi supply is limited, ensuring parameter alignment.

Single Zener Diodes Part Context

The 1N5256B is part of onsemi's standard Zener diode portfolio, widely used in discrete semiconductor applications. The T26A suffix typically denotes specific packaging or shipping configuration. This series is known for reliability in harsh conditions due to its glass passivation and hermetic sealing.

Single Zener Diodes Replacement Considerations

Equivalent parts from Vishay, Microchip, and Panasonic share the 1N5256B designation. Verify pinout and thermal characteristics before substitution. Ensure replacement devices meet the same 30 V and 500 mW specifications.
