PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (Diodes) (Nasdaq: DIOD) today expands its IntelliFET^® portfolio with the introduction of three automotive-compliant* high-side power switches. The second-generation single-channel ZXMS81030SPQ and dual-channel ZXMS82030S14PQ and ZXMS82045S14PQ switches handle high inrush current loads while delivering robust protection and diagnostic capabilities for both the device and load. The devices are a smaller, higher reliability alternative to relays, fuses, and discrete devices for driving 12V automotive loads, such as motors in body and seat control modules, HVAC systems, and lighting applications.

Each device features a vertical DMOS N-channel MOSFET and an integrated controller that protects against short circuits, manages inrush currents, and safeguards against overvoltage conditions, including load dumps. In addition, the switches provide overtemperature protection with auto-restart, alongside protection against electrostatic discharge (ESD) damage. Loss of ground and reverse polarity protection can also be implemented with minimal external components. Onboard diagnostics detect fault conditions and self-protection events, including open load, overload, and overtemperature shutdown.

The ZXMS81030SPQ is available in the SO-8EP and the ZXMS82030S14PQ and ZXMS82045S14PQ are available in the SO-14EP package. Both packages feature exposed underside heatsinks and are thermally efficient. The ZXMS81030SPQ is available at $0.38 and the ZXMS82030S14PQ and ZXMS82045S14PQ are available at $0.71 in 1,000-piece quantities.

The devices are being exhibited at electronica 2026 on Diodes’ Booth 211 in Hall C6 as part of the company’s 48V power tree demonstration, which showcases technologies for efficient power distribution and load control in evolving automotive power architectures. Within the demo, the IntelliFET is used as a load switch, providing a switched 12V output with its associated protection and diagnostic features.

Key Terms

mosfet technical

A MOSFET is a tiny electronic switch used to control the flow of electricity in chips and circuits, functioning like a faucet that turns current on or off and adjusts how much passes through. Investors watch MOSFETs because their performance, cost and availability affect product power efficiency, manufacturing yields and supply chains for industries from consumer electronics to electric vehicles, which in turn can influence companies’ margins and growth prospects.

electrostatic discharge technical

Electrostatic discharge is a sudden flow of electricity between two objects with different electric charges, like the tiny shock you feel after walking on carpet and touching a doorknob. For investors, ESD matters because it can damage electronic components, reduce manufacturing yields, cause product failures or recalls, and increase warranty and repair costs—impacting a company’s production reliability, reputation, and profitability.

load dumps technical

A load dump is a rapid, large-scale sale of a security or group of securities that floods the market and typically drives the price down sharply. It usually happens when one or more holders sell substantial positions at once—by block trade, through algorithmic liquidation, or after a prior accumulation (“loading”)—and is used descriptively rather than as a formal legal or accounting term; similar activity can be part of legitimate portfolio rebalancing, forced liquidation, or manipulative schemes.

iatf 16949 regulatory

An international quality management standard for companies that design and make parts for vehicles, built on a widely used quality framework and tailored to the automotive industry. Like a detailed recipe and inspection checklist that suppliers must follow, it signals consistent production, fewer defects, and eligibility for major auto contracts — information investors use to judge operational reliability, risk of costly recalls, and potential for steady revenue.
