As the electronics industry faces significant supply chain volatility in 2026, ASC Global is issuing an urgent update regarding the severe shortage affecting Diodes Inc. components.
Procurement teams and manufacturers currently relying on Diodes Inc. for discrete semiconductors and timing/logic ICs are being urged to re-evaluate their sourcing strategies to mitigate production risks.
The electronics market is currently dealing with one of the most severe component shortages of the year. Lead times for many Diodes Inc. product families, which averaged 8–10 weeks in 2025, have increased to 48–52+ weeks as of April 2026, with noticeable price escalation.
Two major forces are behind this:
- AI server motherboard demand. Timing & Connectivity ICs, MOSFETs, and SiC Schottky diodes from Diodes Inc. are widely used in AI server power trees, signal conditioning, and switching stages. Hyperscalers expanding AI infrastructure are absorbing massive volumes of these parts
- Demand spillover from broader discrete shortages. Constraints from other discrete manufacturers, such as the ongoing Nexperia crisis, have redirected demand toward Diodes Inc., concentrating pressure on their wafer capacity and backend assembly
The most impacted Diodes Inc. product categories include:
- MOSFETs used in DC-DC conversion and power stages
- SiC Schottky diodes for high-efficiency rectification
- Timing and logic ICs for AI and embedded systems
- Zener and Schottky diodes used in power and control circuits
- Bipolar transistors for analog applications
As manufacturers and procurement teams face growing pressure to maintain production continuity, many organisations are actively qualifying alternative semiconductor sources that match key electrical and package specifications without requiring major PCB redesigns. These efforts focus on maintaining equivalent parameters such as VRRM, IF, VF, trr, RDS(on), VDS, and compatible package footprints.
To support customers during this market disruption, ASC Global is leveraging its position as an authorised distributor for Diotec Semiconductor, a manufacturer specialising in discrete semiconductor solutions for industrial, automotive, commercial, and power applications. Diotec’s portfolio includes Schottky diodes, rectifiers, TVS protection devices, Zener diodes, MOSFETs, and small-signal discretes that align closely with many Diodes Inc. product families currently under allocation.
ASC Global supports customers impacted by the shortage through two primary approaches:
- Global sourcing support for available Diodes Inc. inventory when supply exists
- Specification-aligned alternatives from Diotec Semiconductor with full traceability and manufacturer-backed support
