Is now a good time to invest in upgrading industrial energy efficiency technology?
Vishay Intertechnology has launched four new power modules housed in the SOT-227 package, featuring 650 V superjunction MOSFET technology. These devices, which are currently available, include three single-switch modules and one low side chopper configuration for specialized power management.
Why it matters
By providing a drop-in replacement for existing designs, these modules aim to reduce power losses and optimize switching performance in critical infrastructure like charging stations and hydrogen generation. The rollout addresses the increasing demand for high-efficiency components in power-dense industrial systems.
The modules utilize 650 V superjunction MOSFETs—transistors designed to handle high voltages while minimizing resistance—to balance conduction and switching losses across an operating range of -55 °C to +150 °C.
The players
Vishay Intertechnology
A global manufacturer of semiconductors and passive electronic components that serves the industrial, automotive, and medical markets.
The details
The SOT-227 package is a standard industry footprint that allows for drop-in replacement, meaning engineers can integrate the new modules without modifying their existing printed circuit board (PCB) layouts. The low side chopper configuration specifically incorporates a 650 V silicon carbide (SiC) diode, a wide-bandgap semiconductor material that enables faster switching and higher thermal conductivity than traditional silicon counterparts.
Timeline
October 1, 2026: Vishay Intertechnology introduced the new power modules.
12 weeks: Standard lead time for sample and production quantities.
The Tech Race
This release maintains compatibility with the widely used SOT-227 form factor while integrating modern superjunction and silicon carbide capabilities. It follows a common industry strategy of updating core power-stage performance without forcing customers to undergo expensive board redesigns.
Engineers designing solar, hydrogen generation, and medical imaging systems can utilize these modules immediately as drop-in replacements for current hardware. Production and sample quantities are currently available with a 12-week lead time.
The takeaway
Vishay's move highlights the ongoing push to pack higher voltage and current ratings into established, legacy package footprints. Industry observers should monitor the 12-week lead time to see if supply chain demand for these power-dense components remains stable throughout late 2026.
