About Us
Founded in 2016 and headquartered in Shenzhen, Shenzhen Aoschen Tech. Co., Ltd focuses on power semiconductor supply, part selection and engineering support. Working with dedicated domestic production lines and 10+ assembly partners, we turn wafer-to-test capacity into supply plans that are practical and traceable.

Positioning
Engineering-led supply partner for power tools, motor drives, BMS, ESS, PV inverters, EV chargers and industrial power — covering selection, drop-in evaluation, sample validation and volume supply, with long-term stability as the goal rather than one-off low-price trading.
Why MOS business
- Supply risk — Lead times swing and part numbers keep going EOL; mid-production stop is costly.
- Localisation window — Domestic SGT, Trench and Cool MOS processes are mature and benchmark well against imported parts.
- Our role — Translating process and capacity into selection, validation and buffer-stock plans customers can use.
Our target is not low-price distribution, but a traceable and sustainable power device supply partnership.
Product Portfolio
Low / mid-voltage MOSFET
12–250 V. N-channel / P-channel, SGT and Trench; ultra-low RDS(on), low Qg, high ruggedness.
HV MOSFET / Cool MOS
500–800 V. PFC, LLC, industrial PSU and chargers.
SiC MOS
650–3300 V. High-frequency efficiency for PV, ESS, OBC; strong high-temperature performance.
IGBT modules
