AI Summary

SX34 by FUXINSEMI: Diode Independent 40V 3A Surface Mount SMA(DO-214AC).

The B340A-13-F is a direct drop-in replacement for the SX34 in the same SMA (DO-214AC) package. It matches the original part's key electrical parameters, including 40V reverse voltage, 3A forward current, 0.50V forward voltage drop, and an operating junction temperature range up to 150°C.

  • Drop-in pin-compatible replacement in identical SMA (DO-214AC) package
  • Matching 40V reverse voltage and 3.0A average forward current ratings
  • Identical maximum forward voltage (0.50V at 3.0A) and junction temperature range (-55°C to +150°C)

The B340LA-13-F is a low forward voltage drop variant in the SMA package that improves conduction efficiency. It incurs higher reverse leakage current (2mA max at 40V) and has a lower top operating temperature rating of 125°C.

  • Drop-in pin-compatible replacement in SMA (DO-214AC) package
  • Lower forward voltage drop: 0.45V vs 0.50V at 3A for reduced conduction loss
  • Higher reverse leakage current: 2.0mA vs 0.5mA at 40V
  • Lower maximum junction temperature rating: +125°C vs +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.
