SQJA94EP-T1_GE3-VB Product details

Product introduction:

**Product Introduction** VBsemi SQJA94EP-T1_GE3-VB is a Single N-channel power field-effect transistor using Trench technology, designed for high-current, medium-to-low voltage power conversion and high power density applications. Its LFPAK56 package offers excellent heat dissipation and low parasitic inductance, suitable for demanding scenarios such as automotive electronics, industrial power supplies, and high-performance DC-DC converters. The device provides extremely low on-resistance within an 80V drain-source voltage range (typical value only 6mΩ at 10V gate drive), significantly reducing conduction losses. It supports a ±20V gate drive voltage, with a typical threshold voltage of 1.4V, offering good switching characteristics and anti-interference capability for reliable system driving.
