Taiwan Semiconductor

Taiwan Semiconductor is a Taiwanese discrete-semiconductor maker best known for its surface-mount rectifier lineup, and the profiles here cover its planar Schottky rectifiers in the SMB (DO-214AA) package. The SS24 is a 2 A / 40 V part for low-voltage reverse-polarity protection and DC-DC freewheeling, the SS26 steps up to 60 V, and the SS210 to 100 V — the same 2 A rating across all three, so selection turns on the reverse voltage the circuit actually sees. These planar Schottky parts are workhorses of consumer power supplies, automotive auxiliary circuits and solar bypass applications, where low forward voltage keeps conduction losses down. All three are listed as Active on the official site, but the SS prefix also appears in other manufacturers catalogs, so always pair the part number with the manufacturer name on the BOM. Confirm the complete ordering code including packing suffixes, since reel and tube variants are not interchangeable.

Sourcing notes for Taiwan Semiconductor parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
