AI Summary

KBU8M-E4/51 by Diotec Semiconductor: Bridge Rectifier Single Phase Standard 1 kV Through Hole KBU.

This is a higher-rated alternative in the same KBU footprint. It provides a larger safety margin with a 10A average rectified current capability (vs 8A) and the same 1000V maximum reverse voltage rating.

  • Higher average forward current rating: 10A vs 8A
  • Provides improved safety and thermal headroom
  • Slightly different forward voltage drop characteristics under various load conditions

The KBU810 is an industry-standard generic equivalent part number manufactured by MDD. It serves as a direct form-fit-function replacement with identical core physical and electrical ratings.

  • Industry-standard equivalent part number
  • Pin-compatible drop-in
  • Identical 1000V reverse voltage rating
  • Slightly lower peak forward surge current rating: 200A vs 300A

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.
