AI Summary

US1M by Diodes Incorporated: Diode 1000 V 1A Surface Mount SMA.

The US1M-13-F is the direct, active, lead-free successor from Diodes Incorporated. It offers identical electrical and physical characteristics, serving as a seamless drop-in replacement.

  • Direct active successor from the original manufacturer
  • Exact matching specifications across all electrical and thermal parameters
  • Fully pin-compatible and footprint-compatible standard SMA package

The US1M-E3/61T from Vishay is a highly reliable alternative matching the primary voltage, current, and speed specifications of the original. The only minor difference is a slightly narrower low-temperature operating limit.

  • Tier-1 manufacturer alternative with identical 1000V, 1A ratings
  • Matches the fast 75ns reverse recovery time of the original part
  • Identical physical footprint and landing pattern
  • Slightly narrower operating temperature range of -55°C to 150°C compared to -65°C to 150°C.

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 Diodes Incorporated US1M 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.
