About TDSEMIC
Sichuan Tuodian Semiconductor Co., Ltd. — analog and mixed-signal ICs since 2011.
Company profile
Sichuan Tuodian Semiconductor Co., Ltd. (TDSEMIC) was founded in 2011 and focuses on the production and sales of integrated circuits. We operate as both a brand manufacturer and an authorised distributor, representing more than 30 domestic brands, with a business scope covering wafer design and tape-out, IC packaging and test, and IC solution development and sales.
Our team brings more than 40 years of semiconductor industry experience. In 2010 we established a packaging & test foundry together with an alloy-wire material plant in Suining, Sichuan, and set up a wafer design house in Chengdu the same year, taking custom IC design and packaging/test service orders and delivering system solutions with independent intellectual property. The Suining plant hosts our R&D centre and technical service team.
To pursue higher quality goals and meet brand-customer requirements, we have built enterprise product test standards and a quality system aligned with CNAS and TUV laboratory industry standards.
Product coverage spans power management, circuit protection, discrete semiconductors, display drivers, interface and communication, amplifiers and comparators, memory and logic, and microcontrollers — 1,719 part numbers in total, with pin-to-pin second sources for widely used imported devices wherever the electrical and mechanical fit allows.
How we work with customers
Our FAE team supports design-in: reviewing schematics, proposing alternatives, providing evaluation samples and answering parameter-level questions. For procurement, we quote from a BOM and hold stock on fast-moving part numbers so that prototype builds and small production runs are not held up by minimum order quantities.
