Component data in a 47.8 KB PDF named for 2PD1820A, with the suffix 2 likely marking a document revision.

A 124 KB PDF covering the 1SV128, filed in the schematic category but most likely a manufacturer data sheet for a single diode.

The name 1ss244 indicates a datasheet for a small-signal diode in the Japanese JIS 1SS series, although the file sits in the schematic category.

Component datasheet for the 1N4936, filed under schematics and stored as a 45.5 KB PDF.

At 377 KB this is the largest of a group of PDFs named after 1N part codes; this one is 1N1183, a JEDEC style diode designation, so it is most probably a datasheet even…

Network or RF section from the Samsung Galaxy A30s (SM-A30S) schematic collection, as a 4.29 MB PDF file.

Cellular network section schematic for the Samsung SM-A22 5G, a 5.26 MB PDF. It covers the RF chain, including transceiver, power amplifiers, antenna switches and the…
