# SEMIALT — MOSFET Cross-Reference Platform

A custom MOSFET cross-reference platform developed for SEMIALT, a power semiconductor manufacturer. A visitor enters a competitor’s part number and receives the equivalents from SEMIALT’s own range, or an explicit statement that no qualified equivalent exists. Built on Laravel with a Filament back office; the public pages are pre-rendered and served as static files.

The requirement was a cross-reference engine in which equivalence is decided by technical qualification rather than by similarity scoring. A pair is published only once it clears every mandatory condition: identical polarity, an identical standard package name, a voltage rating no lower than the part being replaced, and on-resistance compared only within matching gate-drive conditions — 10 V against 10 V, 4.5 V against 4.5 V — with every condition present on both parts required to pass. Where two parts share no common test condition, the pair is recorded as not comparable and is withheld from publication. Scoring is applied after qualification and only to order results that already qualify; a high score cannot promote a part that failed a mandatory condition. Thresholds and weights are editable in the back office.
