AI Summary

BAW56 by onsemi: Diode Array 1 Pair Common Anode 85 V 200mA Surface Mount TO-236-3, SC-59, SOT-23-3.

The BAW56LT1G is onsemi's official direct active migration path for the obsolete BAW56. It provides identical electrical ratings, timing characteristics, and physical package dimensions, making it a perfect drop-in replacement with zero design changes.

  • Direct active replacement from the original manufacturer (onsemi) to replace the obsolete legacy part number.
  • Identical SOT-23-3 footprint and standard dual common-anode pinout.
  • AEC-Q101 qualified variant (SBAW56LT1G) is available for high-reliability/automotive use.

This industry-standard replacement from Diodes Incorporated is a highly reliable drop-in alternative. It features enhanced current handling and faster recovery times, allowing it to easily replace the obsolete onsemi device in any signal-switching application.

  • Higher forward continuous current rating of 300 mA (compared to the original 200 mA).
  • Faster reverse recovery time of 4 ns (compared to 6 ns), improving switching efficiency.
  • Widely available industry-standard drop-in alternative.
  • Higher current rating may slightly alter thermal dissipation profile at absolute maximum continuous loads, though beneficial for safety margins.

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 BAW56 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.
