How Diodes makes money
It earns revenue by selling high volumes of semiconductor components to manufacturers in the industrial, automotive, computing, consumer, and communications markets. Sales go through its own sales staff, independent sales representatives, and distributors across Asia, the Americas, and Europe.
What Diodes does
Diodes Incorporated is a broad-line semiconductor supplier headquartered in Plano, Texas, and incorporated in 1959. It offers a large catalog of discrete parts (MOSFETs, SiC MOSFETs, diodes, rectifiers, transistors, and protection devices) along with analog and power-management ICs, LED and audio drivers, Hall-effect sensors, and motor drivers. The company also sells mixed-signal and connectivity chips such as redrivers, high-speed switches, clock ICs, and level shifters, plus CMOS logic, multichip packages, silicon wafers, frequency control products, and contact image sensors. It serves industrial, automotive, computing, consumer, and communications customers across Asia, the Americas, and Europe through direct sales, independent representatives, and distributors.

What is Diodes worth?
On an owner-earnings DCF, Diodes's most-likely value is about $75 versus a recent price near $95 (21% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$37) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.
Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
