Component document for the 2SA1451A in a 230 KB PDF, categorised as a schematic. Under Japanese JIS conventions 2SA designates a PNP transistor aimed at high-frequency…

Schematics for the Nokia N8 in a 6.23 MB PDF file. The name lists no hardware revision, so compare the board version on the PCB before trusting component numbering.

BIOS dump for the Quanta DA0HK8MB6E0 board, revision E, read from a 25Q64FVSIG flash chip, an 8 MB (64 Mbit) Winbond SPI part, and marked ok in the name, meaning it was…

This 234 KB PDF covers the 2SC4738F, indexed as a schematic though it concerns one transistor.

Datasheet in PDF form, 235 KB, named 29C040X and indexed under schematics. The 29C040 code is used for 4 Mbit parallel flash memory, and the trailing X likely marks a…

Datasheet for the AO3401 P-channel MOSFET, the name stating minus 30 V and minus 4 A ratings, filed under schematics as a 498 KB PDF.

Combined datasheet for the SMBTA42 and MMBTA42, surface-mount versions of the high-voltage A42 NPN transistor, in a 525 KB PDF.
