The SI1414DH-T1-GE3 from Vishay Siliconix is a single N-Channel TrenchFET power MOSFET rated at 30 V and 4 A in the ultra-compact SOT-363 (SC-70-6) package. The TrenchFET trench-gate structure achieves a low RDS(on) of 46 mOhm at 4.5 V gate drive, minimizing conduction losses in portable and battery-powered applications. The low gate charge of 5.7 nC enables efficient high-frequency switching with minimal driver power. Lead-free and halogen-free, this device is optimized for space-constrained power management circuits.

The SI1414DH uses Vishay’s TrenchFET technology where vertical trench gates are etched into the silicon substrate and filled with polysilicon to form the gate electrode. This structure provides a much higher channel density than planar MOSFETs, resulting in lower RDS(on) per unit area. When a voltage above the threshold (typically 1 V) is applied between gate and source, an inversion layer forms along the trench sidewalls, creating a conductive channel between drain and source. The low gate charge enables fast turn-on and turn-off transitions, reducing switching losses in high-frequency applications.
