| FFF Compatibility | Matches the 3-pin TO-220 Full Pack (TO-220FP) layout with standard pinout (Pin 1: Anode 1, Pin 2: Common Cathode, Pin 3: Anode 2).Identical isolated package style and mechanical outline (TO-220FP), requiring no hardware or heatsink modification.Meets all primary ratings (100V, 15A per diode / 30A total) and matches the original forward voltage (800 mV @ 15 A). | Standard 3-pin configuration with identical pin assignments in a fully isolated TO-220 full pack.Direct physical matches for the isolated package, allowing a seamless mechanical exchange on the PCB.Directly matches the 100V breakdown voltage and 30A total rectified current capability while providing a lower forward voltage drop. | ||
 AI Summary | NTSJ30U100CTG by onsemi: Diode Array 1 Pair Common Cathode 100 V 15A Through Hole TO-220-3 Full Pack. | This active onsemi component is the most direct upgrade for the obsolete target, keeping the original manufacturer ecosystem. It features identical electrical and physical profiles while providing a superior 175°C junction temperature rating and vastly reduced reverse leakage current.
| An active, high-efficiency substitute from SMC Diode Solutions that features a lower forward voltage drop of 750 mV. This reduces power dissipation under heavy load, making it an excellent drop-in option for thermal-sensitive environments.

You searched one part. Parter watches your whole BOM.
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.
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.
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 onsemi NTSJ30U100CTG 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.
The closest qualified second sources for the onsemi NTSJ30U100CTG are the MBRF30H100CTG (onsemi) and the STF30100C (SMC Diode Solutions), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the NTSJ30U100CTG are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The NTSJ30U100CTG (onsemi) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
