Watch: Industry Insider Episode 2 — Diodes Inc. Shortage Breakdown
What Is Happening With Diodes Inc. Right Now?
Diodes Inc., one of the leading analog IC and discrete semiconductor manufacturers, is at the center of one of the most critical component shortage situations of 2026. A convergence of two powerful demand forces — surging AI infrastructure buildouts and a flood of displaced Nexperia orders — has pushed Diodes Inc.'s manufacturing capacity to its limits.
The result is a perfect storm: exploding lead times, widespread allocation shortages, line-down situations across multiple industries, and a significant price increase implemented with little warning to buyers.
If your supply chain depends on Diodes Inc. components, this is not a situation to monitor passively. The window to act is closing.
Why Is Diodes Inc. Experiencing Shortages?
Force 1: AI Demand Is Driving Unprecedented Orders
The ongoing AI server buildout is creating massive demand for analog ICs and discrete semiconductors. Diodes Inc. products — particularly their Timing/Connectivity ICs, MOSFETs, and SiC Schottky Diodes — are widely used in AI server motherboards. As hyperscalers continue scaling infrastructure, demand for these components continues to climb with no near-term ceiling in sight.
Force 2: The Nexperia Crisis Has Redirected Orders to Diodes Inc.
Beginning in Fall 2025, the Nexperia supply crisis sent a wave of overflow demand directly to Diodes Inc. Customers who could no longer rely on Nexperia for discrete components turned to Diodes Inc. as an alternative source — flooding a manufacturer that was already feeling the strain of AI-driven demand. Top hyperscalers have publicly reported lead time increases, delivery gaps, and price hikes, which signals that the problem is systemic and not isolated.
Diodes Inc. Lead Time Update: From 8 Weeks to 52+ Weeks
This is not a minor fluctuation. Lead times have increased by more than 6x in under 18 months. Industry data on discrete components shows that average lead times across distributors rose 8 days month-over-month in March alone, sitting at approximately 21.5 weeks on average — with Diodes Inc. tracking well above that average.
Discrete Lead Time and Pricing Trends (March 2026)
Diodes Inc. Price Increases: 20% Across the Board
In addition to lead time challenges, Diodes Inc. implemented a pricing increase of approximately 20% across most product lines within the past month. This caught many customers off guard and is compounding the financial impact of the shortage for buyers who are also being forced into the open market to source at premium prices.
Pricing trends for discrete components broadly show a 1.7% month-over-month increase, with Diodes Inc. cited alongside onsemi and Infineon as a key driver of recent pricing upticks. Expectations from top OEMs are that pricing and lead time pressures will continue throughout the rest of 2026 and beyond.
Which Diodes Inc. Products Are Most at Risk?
The following product families are currently experiencing the highest levels of demand pressure and allocation risk:
- Zener Diodes — Surface mount and through-hole variants, including the BZX84 and BZT52C series
- MOSFETs — N-Channel and P-Channel devices including DMC, DMN, and DMP series
- Schottky Diodes — Particularly SiC Schottky and surface mount rectifiers such as the BAT42W, BAT760Q, and BAS521 series
- Logic ICs — Timing, Connectivity, and Clock Fanout Buffers including 74LVC1, 74LVC2, and PI6CB3 series
- Bipolar Transistors — Including BCP531, BCP856B, and BC846B prefixes
Who Is Being Impacted?
Allocation shortages and line-down situations are being reported across three primary customer segments:
Automotive — Automotive-grade components including AEC-Q101 MOSFETs and rectifier diodes are seeing the most severe allocation constraints. Any disruption to automotive supply chains carries heightened risk given long qualification cycles and strict sourcing requirements.
High-Compute and Server Builders — AI server motherboard manufacturers are competing for the same Timing/Connectivity ICs and MOSFETs driving the current shortage. Partial deliveries and allocation gaps are creating production bottlenecks.
Industrial — Industrial customers across power management, motor control, and embedded systems are experiencing delayed deliveries and increasing sourcing costs as the open market absorbs the overflow.
What Should Buyers Do Right Now?
"If you do need to go into the open market to secure buffer stock, now is the time to do it — it's always better to act sooner rather than later."
Here are the recommended steps for procurement and supply chain teams:
- Audit your current Diodes Inc. exposure — Identify all MPNs in your BOM that carry a Diodes Inc. prefix (see high-risk prefixes below)
- Check open purchase orders — Confirm lead times on any outstanding orders and flag anything at risk
- Source buffer stock now — Open market inventory is available today, but is shrinking. Acting now means better pricing and more options
- Evaluate alternative sources — Work with a trusted independent distributor to identify compliant alternatives or cross-references where applicable
- Plan for 2026 and beyond — Top OEMs expect the situation to worsen. Build contingency into your procurement strategy
