AI Summary

IRF530A by onsemi: N-Channel 100 V 14A (Tc) 55W (Tc) Through Hole TO-220-3.

This is an active, modern drop-in replacement by Infineon that meets or exceeds every key specification of the obsolete IRF530A. It provides a higher current limit and lower conduction losses while remaining highly compatible with existing drive circuitry.

  • Pin-compatible drop-in replacement
  • Higher continuous drain current (17A vs 14A)
  • Lower RDS(on) resistance (90 mOhm vs 110 mOhm) for lower conduction losses
  • Slightly higher input capacitance (920 pF vs 790 pF)

This high-performance N-channel MOSFET from STMicroelectronics features an extremely low RDS(on) of 60mOhm and a higher continuous current rating of 26A. It represents a highly reliable and thermally efficient active upgrade for the original device.

  • Significantly lower RDS(on) resistance (60 mOhm vs 110 mOhm) resulting in cooler operation
  • Much higher continuous current capability (26A vs 14A)
  • Higher power dissipation limit (85W vs 55W)
  • Slightly higher gate charge (41 nC vs 36 nC) which may slightly slow switching speeds in weak drive circuits

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 IRF530A 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.
