| FFF Compatibility | Housed in the identical 14-SOIC package and shares the exact pinout layout, making it a direct drop-in replacement.Standard 14-SOIC (0.154" width) package matches the physical dimensions of the original device.Functions exactly like the original but with upgraded ruggedness against voltage transients. | Uses a different logic input scheme (IN/SD instead of HIN/LIN\), resulting in different pin assignments.Housed in the standard 14-SOIC footprint.Output peak drive currents are slightly lower (1.4A source / 1.8A sink vs 1.9A/2.3A), and it uses IN/SD logic instead of independent HIN/LIN\ inputs. | ||
 AI Summary | IR21834SPBF by Infineon Technologies: Half-Bridge Gate Driver IC Inverting, Non-Inverting 14-SOIC. | This is the official active upgrade and direct modern equivalent from Infineon Technologies. It is built on an improved high-voltage process with better noise immunity while remaining completely pin-to-pin and functionally compatible.
| A standard 14-SOIC alternative from Diodes Inc. It provides 600V half-bridge driving with programmable deadtime, but requires a board redesign due to the different IN/SD control logic and pin layout.

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 Infineon Technologies IR21834SPBF 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 Infineon Technologies IR21834SPBF are the IRS21834STRPBF (Infineon Technologies) and the DGD21844MS14-13 (Diodes Incorporated), out of 3 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 IR21834SPBF 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 IR21834SPBF (Infineon Technologies) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
