FFF CompatibilityBoth devices use the standard DO-35 (DO-204AH) axial through-hole package with identical anode and cathode physical pinouts.The physical dimensions and lead spacings are identical, conforming to the standard DO-35 axial diode outline.Matches all electrical parameters including 5.6V nominal Zener voltage, 500mW maximum power, and 11 Ohms maximum dynamic impedance.Features the identical DO-35 (DO-204AH) axial-lead package with standard anode/cathode assignment.Features the same physical outline and mounting pitch as the original obsolete part.Provides the identical 5.6V nominal Zener voltage, 500mW power dissipation, and 11 Ohms dynamic impedance, with only minor leakage current differences.
AI Summary

1N752A by onsemi: Zener Diode 5.6 V 500 mW ±5% Through Hole DO-35.

This is a direct, active JEDEC standard replacement from Central Semiconductor. It offers identical electrical parameters and physical package characteristics, making it a perfect drop-in option.

  • Direct pin-compatible drop-in replacement with identical JEDEC specifications
  • Currently active and widely available from alternative semiconductor manufacturers
  • Maintains standard 5.6V Zener voltage and 500mW power dissipation rating

The 1N5232B is onsemi's recommended active parametric replacement in the same family. It shares the identical DO-35 physical footprint and core Zener specifications, with negligible differences in leakage current.

  • Same manufacturer (onsemi) with active production lifecycle
  • Parametric equivalent with matching 5.6V Zener voltage and 500mW power ratings
  • Same DO-35 (DO-204AH) physical footprint requiring no board modifications
  • Slightly different reverse leakage current specification (5 µA at 3V vs the original's 5 µA at 2.5V)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.

Frequently asked questions

Yes. The onsemi 1N752A is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
