- TrenchFET power MOSFET technology for optimized performance
Applications
- Primary side switching
- Synchronous rectification
Procurement Notes
Verify the specific ordering suffix against official documentation before procurement. The -E3 suffix indicates lead-free construction. Confirm that the component meets RoHS and IEC 61249-2-21 halogen-free requirements if mandated by your design specifications. Cross-reference the manufacturer part number directly with authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this component when a compact dual N-channel solution is required for low-voltage applications. The 40 V rating and low on-resistance make it suitable for efficient power management. Ensure the PCB layout accommodates the PowerPAK 1212-8 footprint and provides adequate copper area for thermal dissipation given the package's small profile.
Part Context
This component belongs to the Vishay Siliconix Si72xx series of dual MOSFETs. It is designed to replace single-channel solutions in space-constrained designs. The PowerPAK 1212-8 package offers a reduced profile compared to traditional SO-8 packages while maintaining robust thermal characteristics for surface mount assembly.
Replacement Considerations
Consult the official datasheet or manufacturer for verified replacement options. No public substitute part numbers are confirmed in the provided source material.
