Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel format. Confirm compliance requirements against specific project standards. Validate thermal equilibrium conditions during testing. Ensure lead temperature constraints are met during soldering processes. Cross-reference datasheet revision numbers for accurate parameter data.

Single Zener Diodes Selection Notes

Select this component when a 75 V regulation point is required in through-hole designs. Consider the 1.3 W power dissipation capability for thermal management. Evaluate the 175 Ω dynamic resistance for noise-sensitive applications. Compare against lower voltage variants if different regulation points are needed.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N4728A to 1N4761A series of Zener diodes. The series covers a wide range of voltages from 3.3 V to 75 V. All devices share the same DO-41 package and general structural characteristics. The -TR suffix indicates the specific reel packaging configuration.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4761A parts in the DO-41 package. Verify matching Zener voltage, power rating, and package dimensions before substitution.
