Single FETs, MOSFETs Procurement Notes

Verify the component marking code 'BR' against the datasheet to confirm authenticity. Ensure the ordering suffix matches '-T1-GE3' for tape-and-reel packaging and halogen-free compliance. Confirm that the specific batch meets RoHS standards as defined by Vishay Intertechnology. Cross-reference the document number 65526 for the most current technical specifications before finalizing procurement.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring a miniaturized single-channel P-channel switch. The SC-70 package is suitable for space-constrained portable electronics. Evaluate the on-resistance requirements against available gate drive voltages, as RDS(on) varies significantly between -4.5 V and -1.5 V logic levels. Consider the thermal resistance characteristics when designing PCB footprints for steady-state operation.

Single FETs, MOSFETs Part Context

This part belongs to the Vishay Siliconix LITTLE FOOT series of single-channel MOSFETs. It utilizes a copper leadframe variant designated by the 'EDH' suffix, which provides superior thermal performance over traditional Alloy 42 leadframes. The device is designed for small to medium load applications where high current density and efficient heat dissipation are required within a minimal footprint.

Single FETs, MOSFETs Replacement Considerations

Consult Vishay documentation for direct replacements within the Si14xxEDH family. Verify pinout compatibility and thermal resistance ratings when substituting components from other manufacturers. Ensure any alternative device supports the required -20 V drain-source voltage and fits the SC-70 footprint.
