Each channel is rated for 20 V drain-source and 4.4 A continuous drain current at 25 °C, with a maximum on-resistance of 40 mOhm at 4.5 V gate drive. The 1206-8 ChipFET package keeps the footprint small — the flat leads sit flush on the board, making it a fit for dense layouts where vertical clearance is tight. The dual-channel configuration saves board area compared to two single MOSFETs when you need independent load switching or a half-bridge leg. ## Rds(on) and gate charge at logic-level drive The 1 V max gate threshold at 250 µA means the part turns on cleanly from a 3.3 V logic signal — no separate gate-driver IC needed for moderate switching frequencies. Total gate charge is 7.5 nC at 4.5 V. That is low enough that a microcontroller GPIO can drive the gate directly at tens of kHz without excessive switching loss. ## Temperature grade and deployment envelope The junction temperature range spans -55 °C to 150 °C, which is the military-grade envelope. This part suits avionics, satellite payloads, and downhole instrumentation where the ambient can swing well beyond industrial limits. The 1.1 W maximum power dissipation in the ChipFET package is the thermal constraint — derate for high ambient or limited copper area on the PCB.","metaTitle":"SI5908DC-T1-E3 TrenchFET Dual N-Ch MOSFET, 20V 4.4A","metaDescription":"SI5908DC-T1-E3 dual N-channel logic-level MOSFET from Vishay TrenchFET series. 40 mOhm Rds(on) at 4.5V, 7.5 nC gate charge, -55 to 150°C.
