AI Summary

STN3NF06L by STMicroelectronics: N-Channel 60 V 4A (Tc) 3.3W (Tc) Surface Mount SOT-223.

This N-channel MOSFET serves as an excellent upgrade alternative, matching the 60V voltage rating and the physical footprint of the original STN3NF06L. It features a lower RDS(on) of 50 mOhm and a higher continuous current rating of 4.8A, resulting in reduced thermal dissipation and enhanced system efficiency. Logic-level compatibility is maintained with a low threshold voltage suitable for direct microcontroller drive.

  • Lower RDS(on) of 50 mOhm vs 100 mOhm for improved efficiency
  • Higher continuous drain current rating of 4.8A vs 4A
  • Identical SOT-223 package footprint and pin assignment
  • Slightly higher input capacitance (1063 pF vs 340 pF) which may slightly slow switching speeds in high-frequency applications

The DMN6068SE-13 is a direct drop-in replacement that meets or exceeds the critical parameters of the STN3NF06L. It provides a robust 60V breakdown voltage rating and a 4.1A drain current capability combined with a lower on-resistance of 68 mOhm. The gate drive characteristics are fully compatible with logic-level control.

  • Lower RDS(on) of 68 mOhm vs 100 mOhm for cooler operation
  • Slightly higher continuous drain current of 4.1A vs 4A
  • Identical package footprint and pin configuration
  • Slightly higher gate-source threshold voltage of 3.0V max vs 2.8V max under specific conditions
  • Larger gate charge (10.3 nC @ 10V) requiring slightly more driver current

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.
