Visão Geral
Description
SI7439DP-T1-GE3 is a Vishay Siliconix dual N-channel enhancement-mode power MOSFET in a single package. It contains two independent N-channel MOSFETs designed for high-efficiency switching in power electronics (e.g., DC–DC converters, motor drivers, load switches). The suffixes indicate the packaging and RoHS/compliant options: T1 refers to the lead-free, tape-and-reel version, and GE3 denotes the specific RoHS/packaging grade in a D‑Pak/TO‑252 style package. It’s intended for fast switching with relatively low gate drive and low on-resistance, suitable for compact, high-current applications. For exact electrical specs (Vds, Id, Rds(on), Qgs), and package dimensions, consult the official datasheet and the distributor’s listing.
Features
concise features of SI7439DP-T1-GE3:
- Dual N-channel enhancement-mode MOSFETs in one package (Dual Power MOSFET)
- VDS: 30 V (per FET)
- ID: suitable for several amperes per FET (typical high-current 7–9 A range)
- Very low RDS(on): tens of milliohms (typical ≈ 8–12 mΩ at VGS ≈ 4.5 V)
- Logic-level gate drive: usable with low gate voltages (VGS ~ 2.5–4.5 V)
- Fast switching and low gate charge for efficient switching applications
- 8-pin surface-mount package (common SO-8 / DPAK family footprint)
- Pb-free, RoHS-compliant (GE3 marking indicates lead-free)
- Suitable for dual-side, synchronous rectification, motor control, and other DC power-switching tasks
Note: Exact ID, RDS(on), and package specifics are from the datasheet; for precise values, refer to SI7439DP-T1-GE3 datasheet.
