About us
MISEMICON focuses on discrete semiconductors and passive components for industrial OEM and EMS programs—documented RFQs, not brochure-level replies.
Your line card partner
MISEMICON works with dedicated lines for Schottky and standard rectifier diodes, TVS and ESD protection, and chip resistors and MLCC capacitors. Production focuses on mainstream SMD packages for power supplies, chargers, adapters, lighting, and industrial control.
Since 2007, our team has supported industrial, EMS, and OEM customers worldwide with component selection and supply. Rather than a pure trading desk, MISEMICON is organized around stable manufacturing partners and documented processes—from die and packaging through test and outbound logistics.
For each program we align device curves, package and temperature ratings, and quality documentation (for example ISO and RoHS/REACH where required) with your AVL and drawing set. Questions go to applications-aware engineers, not brochure-level replies.
Open Products to see the main lines—Schottky and rectifier diodes, Zener and small-signal diodes, TVS and ESD protection, and chip resistors and capacitors—and use Contact to send your part list or schematic context for review.
- ISO-aware processes and RoHS/REACH documentation where your specifications require it.
- Line-by-line alignment to your AVL with documented alternates when supply tightens.
- English-language RFQs with electrical and commercial detail on business days.
