Vishay Intertechnology Standard-Level 40 V MOSFETs Prevent False Triggering and Reduce Noise in Motor Control Circuits

Vishay Intertechnology introduced four new 40 V TrenchFET Gen IV n-channel power MOSFETs (SIR5402DP, SIR5404DP, SIR5406DP, SIR5408DP) in PowerPAK SO-8 packages. These devices feature high minimum gate-source threshold voltage (>2.5 V) and optimized Qgd/Qgs ratios (<1) to prevent false triggering and reduce noise in motor control applications. The MOSFETs offer on-resistance values from 0.9 mΩ to 2.5 mΩ and are targeted at BLDC motors, power tools, drones, and automation systems.
