The SI4967DY-T1-E3 is a P-channel MOSFET manufactured by Vishay Siliconix, utilizing TrenchFET technology. It features an SOIC-8 surface-mount package and operates on silicon technology. The device is designed for SMD/SMT installation and belongs to the SI4 series of MOSFETs. Official documentation indicates it is an end-of-life product with restricted availability in certain regions. The component is RoHS compliant and functions as a discrete power transistor within electronic circuits.
Verify current availability status directly with authorized distributors, as this component is listed as end-of-life. Confirm RoHS compliance details through official datasheets before integration. Check regional sales restrictions and ensure supply chain stability for long-term production needs due to discontinuation status.
Consider alternative P-channel MOSFETs from the same manufacturer if long-term supply is required. Evaluate package compatibility with existing PCB footprints. Review thermal characteristics and voltage ratings against specific circuit requirements to ensure adequate performance margins.
This part belongs to the Vishay Siliconix SI4 series, which focuses on power MOSFET solutions. The TrenchFET branding indicates advanced gate structure technology aimed at reducing on-resistance. The -T1 suffix typically denotes reel packaging, while -E3 signifies lead-free composition.
