Cash Cows
Standard Discrete Semiconductors
Standard Discrete Semiconductors are a cash cow for ON Semiconductor (onsemi), with diodes and transistors covering an estimated 35-40% share of the global discrete market and generating roughly $1.6B in annual revenue (2025 run rate), providing stable free cash flow and low marketing spend. These parts appear in nearly every electronic device, so demand is steady and capital intensity is moderate. High-volume production and yield improvements lift gross margins to about 38-42%, funding onsemi's $1.2B+ investment in Silicon Carbide expansion through 2026. Continued margin-led cash generation reduces reliance on external financing for strategic shifts.
General Purpose Analog ICs
Onsemi's general-purpose analog ICs-op amps, comparators, and voltage references-serve a mature global base and generated roughly $1.1 billion in FY2024 revenue, reflecting stable demand and ~25% segment gross margin.
Market growth is low (mid-single digits projected), but onsemi holds a leading share thanks to reliability and long lifecycles, keeping these products as cash cows.
They need minimal CapEx and R&D reinvestment versus new products, freeing about $300-350 million annually to service debt and fund dividends.
Standard Power MOSFETs
Standard silicon power MOSFETs remain the workhorse for low-to-medium voltage power electronics, covering ~70% of onsemi's discrete MOSFET revenue and addressing automotive, industrial, and consumer markets where SiC is not yet cost-effective.
onsemi is a market leader, leveraging fully depreciated fabs-reducing capex by an estimated $200-300M annually-and converting stable gross margins (~28% in FY2024) into free cash flow.
These MOSFETs sit in the mature lifecycle stage, generating predictable cash that funded ~40% of onsemi's $1.3B 2024 R&D and M&A spend to scale SiC and other Question Marks.
Mature Logic and Signal Management
ON Semiconductor's mature logic and signal-management products-legacy logic gates and signal switching used in industrial and telecom gear-generate steady revenue with limited growth; in 2025 this segment likely contributes low-single-digit organic growth while supporting 2024 gross margin uplift to 40% company-wide.
Competition is narrow around existing design-ins, so management prioritizes operational efficiency and tighter supply-chain costs to protect mid-high single-digit EBITDA margins on these lines.
- Stable end-markets: industrial & telecom

Dogs
Commodity Computing Components
Commodity computing components for legacy PCs and laptops face global volume declines-IDC reported a 12% Y/Y drop in PC component demand in 2024-and fierce price pressure from low-cost Asia vendors; margins often sit below 5%. onsemi holds a low share in this commoditized segment, with negligible brand loyalty and accelerating unit-price erosion. These SKUs are strong divestiture candidates as onsemi shifts to intelligent power and sensing, where 2024 adj. gross margins exceeded 30%.
Legacy Small Signal Diodes
Legacy small-signal diodes at ON Semiconductor (onsemi) occupy a shrinking market as designers favor integrated protection and switching networks; global small-signal diode unit demand fell ~7% CAGR 2019-2024, pressuring margins.
onsemi keeps a slim footprint to serve legacy customers, but management reported these SKUs typically hover near breakeven, contributing minimal operating cash-estimated <$20M annual EBITDA across the line in 2024.
These parts are often cash traps, occupying wafer capacity and staffing that could instead support higher-margin power MOSFETs or SiC products, where onsemi targets mid-teens EBITDA margins and much stronger growth.
Discontinued Audio Signal Processors
As consumer audio shifts to integrated SoCs, ON Semiconductor's discontinued audio signal processors are low-share products in a shrinking discrete market; global discrete audio IC revenue fell ~18% from 2019-2024 to about $420M, reducing relevance.
onsemi halted major R&D and cut segment opex; audio contributed under 1% of 2024 revenue (~$25M CC), so the units are being phased out as contracts expire through 2025-26.
Mature Smart Card Solutions
The market for traditional smart card ICs is mature and price – competitive; global smart card IC revenue fell to about $1.1B in 2024 (down ~3% YoY), leaving onsemi with a small, stagnant share that yields low margins and limited growth.
These units tie up admin and R&D resources without fitting onsemi's strategy focused on automotive and industrial megatrends, where 2024 revenue mix shifted toward power and sensors; the smart – card line is a legacy business dragging margins.
- Market size ~ $1.1B (2024)
- onsemi share: small, stagnant; low margin
- Consumes admin/R&D resources
- Misaligned with auto/industrial focus
Low-Growth PC Peripherals
ON Semiconductor's legacy controllers and interface ICs for PS/2, USB-A 2.0 and other older peripheral standards saw unit demand drop ~18% CAGR 2018-2024 as USB-C adoption hit ~55% of new device designs by 2024; these parts have low market share and negligible growth, so they act as Dogs in the BCG matrix and add little strategic value.
Management mostly minimizes R&D and manufacturing support, records thin margins (gross margin ~12% vs company avg ~32% in FY2024) and actively seeks divestiture or end-of-life paths for these lines.
- Decline: ~18% CAGR 2018-2024
- USB-C penetration: ~55% of new designs by 2024
- Gross margin on legacy ICs: ~12% (FY2024)
