Manufacturer Documentation
Technical values were checked against STMicroelectronics documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
HSP051-4M10 selection and design context
HSP051-4M10 is cataloged as a ESD Protection Array in the HSP051 family. Its recorded function is four-line ultra-low-capacitance ESD protection array for high-speed interfaces. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Protected Lines: 4. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Bandwidth: 10 GHz class. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Line Capacitance: 0.2 pF typical between I/O lines. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- ESD Contact Rating: ±8 kV IEC 61000-4-2. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this protection device, confirm working voltage, clamping behavior, surge or ESD rating, capacitance, polarity and placement relative to the protected interface. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for HSP051-4M10
The recorded package is 10-lead micro-QFN, 2.5 mm × 1.0 mm, the temperature range is -40°C to +150°C junction, and the lifecycle status is Obsolete as of 2026-07-21. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
HSP051-4M10 FAQ
