| FFF Compatibility | HSP053-4M5 is packaged in the identical 5-pin µQFN package with a 0.5 mm pitch and matching symmetric rail-to-rail I/O pinout.The physical package size (1.3 mm x 0.8 mm x 0.38 mm) is identical, sharing the same footprint and mounting style.The working voltage matches at 5V, with improved high-speed performance due to lower junction capacitance. | The pinout layout features GND on pin 2 and identical symmetric rail-to-rail I/O channels on pins 1, 3, 4, and 5.Matches the 1.3 mm x 0.8 mm surface-mount DFN1308-5 package exactly.Features an identical 5V reverse standoff voltage and 3A peak pulse current handling. | |
 AI Summary | HSP051-4M5 by STMicroelectronics: 11.3V Clamp 3A (8/20µs) Ipp Tvs Diode Surface Mount 5-µQFN (1.3x0.8). | This is the manufacturer's official direct replacement part for the obsolete HSP051-4M5. It offers an identical physical footprint, same 5V working voltage, and significantly better bandwidth for high-speed differential signals due to its lower junction capacitance. Its breakdown voltage is slightly lower but fully compatible with standard 5V logic lines.
| This is an excellent cross-manufacturer alternative from MCC housed in the exact same DFN1308-5 (1.3 x 0.8 mm) package. It matches the original's 5V working voltage and 3A peak pulse current capacity while offering lower junction capacitance for cleaner high-speed transitions. Its slightly higher clamping voltage remains highly effective for ESD protection.

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 STMicroelectronics HSP051-4M5 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 STMicroelectronics HSP051-4M5 are the HSP053-4M5 (STMicroelectronics) and the ESD5V0PW-TP (MCC (Micro Commercial Components)). Each is compared against the original on fit, form and function in the table above.
Yes. The leading alternatives to the HSP051-4M5 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.
The HSP051-4M5 (STMicroelectronics) is a part in the Transient Voltage Suppressors (TVS) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
