AI Summary

NTSJ30U100CTG by onsemi: Diode Array 1 Pair Common Cathode 100 V 15A Through Hole TO-220-3 Full Pack.

The MBRF30H100CTG is an active, direct cross-reference from onsemi that maintains the exact physical form factor and electrical ratings. It offers superior reverse leakage specifications and a higher junction temperature ceiling, making it a highly reliable and safe replacement for the obsolete NTSJ30U100CTG.

  • Direct drop-in replacement from the same manufacturer (onsemi)
  • Higher maximum junction temperature (175°C vs 150°C)
  • Significantly lower maximum reverse leakage current (4.5 µA vs 675 µA)

The MBRF30100CT is a highly common planar Schottky alternative that matches the physical package and pinout perfectly. While it is widely available, its planar structure leads to a slightly higher forward voltage drop and reverse leakage, representing a minor efficiency trade-off.

  • Cost-effective, highly available standard planar Schottky array
  • Maintains the exact same 100 V reverse voltage and 30 A total current ratings
  • Slightly higher maximum forward voltage (0.85 V vs 0.80 V) which can increase power dissipation.
  • Higher reverse leakage current (1 mA vs 675 µA).

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.
