Quick Takeaways
- Vishay introduced four 40 V TrenchFET Gen IV standard-level n-channel power MOSFETs in the PowerPAK SO-8 single package.
- The company says the devices are optimized for noisy motor control circuits and combine a minimum gate-source threshold voltage above 2.5 V with Qgd / Qgs ratios below 1.
- Vishay identifies BLDC motors, power tools, drones, and automation systems as target applications for synchronous rectification and DC/DC conversion.
- Samples and production quantities are stated as available now, with a 13-week lead time.
Industry Update
Vishay Intertechnology announced four new 40 V TrenchFET Gen IV standard-level n-channel power MOSFETs on July 7, 2026. The Vishay Siliconix SIR5402DP, SIR5404DP, SIR5406DP, and SIR5408DP are supplied in a 6.15 mm by 5.15 mm PowerPAK SO-8 single package.
According to Vishay, the devices are designed for noisy motor control circuits. The company highlights a minimum gate-source threshold voltage greater than 2.5 V and Qgd / Qgs ratios below 1, with the goal of reducing false triggering and gate-induced voltage fluctuations.
The product family spans typical on-resistance values from 0.9 milliohm to 2.5 milliohm at 10 V, with gate charge values from 32.6 nC to 82 nC. Vishay states that the MOSFETs are 100 percent RG- and UIS-tested, RoHS-compliant, and halogen-free.
Buyer Considerations
For BLDC motor control boards and compact automation drives, switching-device behavior can affect noise margin, thermal design, and control reliability. Buyers comparing motor controllers should check whether the power stage, gate driver, PCB layout, and protection design match the electrical environment of the target motor and duty cycle.
The stated application list is broad: BLDC motors, power tools, drones, and automation systems. That makes the announcement relevant for OEM teams sourcing control electronics for battery-powered motion products, compact actuators, and industrial equipment where board space and switching losses matter.
The 13-week lead time is also worth tracking during supplier qualification. Buyers should confirm current availability, approved alternates, package compatibility, and qualification status before locking a motor control design or production schedule.
