The TrenchFET technology uses a vertical trench-gate structure that minimizes the cell pitch while maximizing channel density, resulting in the low 23 mOhm on-resistance for a 100V device in an SOIC-8 footprint. The 11.1A continuous drain current rating supports medium-power DC-DC converter and motor drive applications. The 19.6 nC typical gate charge at 10V enables efficient switching at frequencies up to 500 kHz with modest gate drive capability. The SOIC-8 package provides a compact footprint with gull-wing leads for reliable surface-mount assembly. The T1-GE3 suffix indicates tape and reel packaging with lead-free (RoHS compliant) terminations. Note: This device is listed as NRND (Not Recommended for New Designs) by Vishay.","working_principle":"The SI4056DY-T1-GE3 uses Vishay's TrenchFET technology where the gate electrode is formed in a vertical trench etched into the silicon. The trench is lined with gate oxide and filled with polysilicon, creating a vertical channel on both sidewalls of the trench. This structure dramatically increases the channel width per unit area compared to a planar MOSFET, reducing the specific on-resistance (RDS(ON) x area). When VGS exceeds the threshold voltage (1.0-2.8V), an inversion layer forms on the trench sidewalls, creating a conductive channel between the source (top) and drain (bottom). The 23 mOhm RDS(ON) at 10V VGS is achieved through thousands of parallel trench cells that share the drain current. The 100V breakdown voltage is maintained by a lightly-doped drift region between the channel and the drain. The gate charge of 19.6 nC at 10V VGS represents the total charge that must be supplied to the gate to switch the MOSFET from off to on, consisting of Qgs (2.7 nC), Qgd (7.8 nC), and Qg total. The Miller plateau region during Qgd determines the switching transition time and associated losses.","pin_description":"
