|---|---|---|---|---|
| FFF Compatibility | Both the target and Littelfuse SMAJ58CA share the standard DO-214AC (SMA) footprint and are bidirectional, non-polar devices, meaning they mount onto the existing PCB land pattern with no modifications.The physical envelope, lead pitch, and profile height of the DO-214AC package match the original specification exactly.Electrical specifications, including reverse stand-off voltage (58V), breakdown voltage range (64.4V to 71.2V), clamping voltage (93.6V), and peak pulse current (4.3A), match or exceed the original parts specs. | Uses the identical industry-standard DO-214AC (SMA) footprint with a bidirectional, non-polar terminal layout.The physical package dimensions and mounting styles are completely identical to the target part.All critical electrical limits such as 58V breakdown stand-off, 93.6V clamp, and 400W power rating are identical. | ||
 AI Summary | SMAJ58CA by Diodes Incorporated: 93.6V Clamp 4.3A Ipp TVS Diode, DO-214AC (SMA). | The Littelfuse SMAJ58CA is a highly reliable direct drop-in replacement that matches all physical, mechanical, and electrical specifications of the obsolete Diodes Inc. part. It is widely stocked and in an active lifecycle stage.
| Bourns is a premium manufacturer of circuit protection components, and their SMAJ58CA represents a high-reliability second-source alternative that matches all parameters of the obsolete original part.

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 Diodes Incorporated SMAJ58CA 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 SMAJ58CA are the SMAJ58CA (Littelfuse Inc.) and the SMAJ58CA (Bourns Inc.), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Yes. The leading alternatives to the SMAJ58CA are fit-, form- and function-compatible — the same package and pinout with matching key electrical specifications — so they drop in without PCB changes. Always confirm the parameters critical to your design against the alternative's datasheet before committing.
