| FFF Compatibility | The physical layout, mounting package (DO-214AC SMA), and 2-pin polarity configuration are identical to the original Diodes Incorporated part.The physical dimensions and package style (SMA) are identical and fully interchangeable on existing land patterns.Maximum forward voltage is slightly higher (1.7V max at 1A vs. 1.3V max at 1A for the original), which may slightly increase power dissipation in high-duty-cycle conduction paths. | Standard SMA (DO-214AC) footprint and 2-pin anode/cathode pinout match the original part exactly.Physical package outlines and height clearances align with standard SMA dimensions.The forward voltage is 1.7V max at 1A, which is higher than the original 1.3V rating. | ||
 AI Summary | ES1J by Diodes Incorporated: Diode 600 V 1A Surface Mount SMA. | This is an active, highly available replacement from Taiwan Semiconductor with identical physical characteristics. It matches the original part's 600V breakdown voltage, 1A current limit, and 35ns ultra-fast recovery time. However, it exhibits a slightly higher forward voltage of 1.7V under full load.
| MCC's ES1J-LTP is an active, robust replacement that offers the same voltage, current, and speed capabilities in an identical SMA package. It features an extended operating temperature range up to 175°C, though it has a higher maximum forward voltage of 1.7V.

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 Diodes Incorporated ES1J 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 Diodes Incorporated ES1J are the ES1J (Taiwan Semiconductor Corporation) and the ES1J-LTP (MCC (Micro Commercial Components)), out of 4 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 ES1J 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 ES1J (Diodes Incorporated) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
