Thông số kỹ thuật
This is a single P-channel TrenchFET power MOSFET from Vishay Siliconix, adopting third-generation trench process and PowerPAK SO-8 leadless package, featuring ultra-low on-resistance and large current carrying capacity, widely used in power path switching and high-efficiency power management circuits。
Part Number Definition
SI7145DP stands for single P-channel MOSFET with PowerPAK SO-8 package. T1 represents tape-and-reel packaging for automatic SMT placement on production lines. GE3 indicates lead-free and halogen-free environmental compliant version.
Core Electrical Parameters
Drain-source breakdown voltage VDS reaches 30V. Under adequate heat dissipation, continuous drain current can hit 60A. When gate drive voltage is 10V and test current 25A, maximum on-resistance is only 2.6mΩ; under 4.5V logic drive voltage, maximum Rds(on) is 3.75mΩ, which greatly reduces conduction power consumption and heat generation during long-term heavy-load operationVishay Int…. Gate-source withstand voltage range is ±20V, threshold voltage maximum 2.3V, compatible with 3.3V and 5V system IO direct drive. Typical total gate charge is 275nC at 10V drive, supporting medium-high frequency switching design. The component passes 100% UIS avalanche energy testing and gate resistance screening, with strong anti-surge and anti-interference ability. Maximum power dissipation is 104W under ideal cooling condition, junction temperature working range from -55℃ to 150℃DigiKey.
Packaging and Assembly Specifications
Package type is PowerPAK SO-8 exposed pad surface mount package with body dimension 5.89mm×4.90mm. The bottom large-area copper pad provides excellent heat conduction channel to effectively lower chip temperature rise during high-current working state. Moisture sensitivity level is MSL1, no mandatory time limit for reflow soldering after vacuum package opening. Standard reel packaging with fixed quantity per reel matches feeding requirements of fully automatic placement equipment on production lines。
Environmental and Compliance Standards
The whole product is lead-free and halogen-free, fully complying with mainstream international environmental protection and restriction regulations. Compact leadless packaging saves PCB layout area, reduces parasitic inductance of wiring, and improves the stability of power switching circuits.
