Compare two revisions of a MOSFET datasheet

Compares two revisions of a discrete MOSFET datasheet.

Validation: 85 hand-read values from 5 real MOSFET datasheets (TI, Nexperia, Infineon, Wolfspeed: 99 % found, 0 wrong values) and 5 real revision pairs without a false change; a real pair with an actual value change has not been tested yet. Every response carries the warning VALIDATION_SCOPE. IGBTs, modules, diodes and gate drivers are refused with OUT_OF_SCOPE.

Input: multipart old_file and new_file (or old_file_url, new_file_url): text-based PDFs, each up to 20 MiB and 60 pages. Optional options as a JSON string following /v1/schemas/datasheet-compare-options: target_mpn (exact part number for family sheets).

Behaviour: the ReLaEx engine (relaex, profile mosfet_table_v1) extracts VDS, ID, VGS, RDS_ON, VTH, QG, RTH_JC and TJ_MAX from the datasheet tables with min/typ/max, units and test conditions, pairs only identical contexts (same statistic, unit and conditions) and computes deltas in canonical units. Changed conditions, one-sided values and unreadable rows are open cases without deltas. Review priority rules mosfet-risk-0.1 (R001–R009): heuristic, without design context. Nothing is guessed; a missing value is never reported as removed.

Output: ApiResponse with the engine report (schema 0.2.0): documents (part number, revision, date, SHA-256), observations with page, table, row, box and quote, findings (status, delta, percent, quality, rule, actions), summary (coverage, counts, review priority, open cases, limitations).

Errors: 400 INVALID_PDF, ENCRYPTED_PDF, OCR_REQUIRED; 413 FILE_TOO_LARGE, PAGE_LIMIT_EXCEEDED; 422 PART_MISMATCH, AMBIGUOUS_PART, INVALID_OPTIONS; 429; 504.

Languages: responses are in English. Error, warning and rule codes are stable and language-neutral; agents may translate messages for the user. Datasheet labels in English or German are recognised.

Access: open, rate-limited per IP and per MCP session; an X-API-Key header raises the limit. Uploaded files are processed in memory and never stored. Also available as MCP tool datasheet_compare at /mcp (Streamable HTTP).
