概述
Description
The SI2347DS-T1-GE3 is a P-channel MOSFET from Vishay Siliconix, designed for power management applications. Key features include:
- Voltage Rating: -20V (drain-to-source)
- Current Rating: -6.3A (continuous drain current)
- Low On-Resistance (RDS(on)): 28mΩ (max at VGS = -4.5V)
- Gate Threshold Voltage (VGS(th)): -1V (typical)
- Compact Package: PowerPAK® SC-75 (1.6mm x 1.6mm), ideal for space-constrained designs.
It’s optimized for load switching, battery protection, and DC-DC conversion in portable devices, power supplies, and automotive systems. The T1-GE3 suffix indicates halogen-free, RoHS-compliant packaging.
Advantages:
- High efficiency due to low RDS(on).
- Fast switching performance.
- Small footprint for high-density PCB layouts.
Typical applications include power distribution, motor control, and reverse polarity protection.
