AI Summary

IR21834SPBF by Infineon Technologies: Half-Bridge Gate Driver IC Inverting, Non-Inverting 14-SOIC.

This is the direct, manufacturer-recommended successor to the obsolete IR21834S. It uses an updated, highly robust silicon-on-insulator (SOI) process, maintaining complete physical and functional drop-in compatibility.

  • Direct manufacturer recommended replacement
  • Active and preferred status
  • Upgraded, more robust HVIC and latch-immune process technology
  • Supplied in Tape & Reel packaging rather than the original Tube format

This is the exact Tube-packaged sibling in the newer IRS series. However, because manufacturers are phasing out tube delivery formats, this part is also classified as obsolete/EOL and shares the same lifecycle risks as the original.

  • Exact same Tube packaging as the original queried part
  • Identical pinout, electrical parameters, and timing characteristics
  • Obsolete / Last-Time-Buy status, introducing identical long-term lifecycle risk

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.
