AI Summary

BAT42W by Taiwan Semiconductor: Diode 30 V 200mA Surface Mount SOD-123.

This is a high-reliability, commercial-grade drop-in alternative from Vishay. It perfectly duplicates the electrical and mechanical parameters of the original part, with an optional AEC-Q101 grade available in the same series.

  • Excellent thermal stability from a top-tier manufacturer
  • Ordering scheme provides clear paths for commercial (-E3) vs. AEC-Q101 qualified (-HE3_A) grades
  • Fully matches the 30V, 200mA ratings and standard 5ns recovery time

This is a standard second-source commercial alternative from MCC in the same SOD-123 package, offering seamless drop-in compatibility across all electrical and thermal operating profiles.

  • Extremely cost-effective second-source option
  • Identical 30V, 200mA, and 5ns electrical parameters
  • Fully compatible SOD-123 footprint for easy assembly integration

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.
