Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'H' to confirm lead-free status and package variant. Cross-reference datasheet revision dates to ensure compatibility with current JEDEC qualification tests. Confirm that the -20 V rating meets system voltage requirements. Check moisture sensitivity levels for proper storage and handling procedures during assembly.

Single FETs, MOSFETs Selection Notes

Select this component for low-voltage P-channel switching applications requiring moderate current handling. The 21 mΩ R_DS(on) at 4.5 V drive is suitable for standard logic-level control. Ensure gate drive voltages remain within specified limits to maintain optimal on-state performance and prevent breakdown.

Single FETs, MOSFETs Part Context

This part belongs to the BSO200P series of P-channel MOSFETs. It shares the OptiMOS™ P architecture with siblings like the BSO200P03S-H but differs in voltage and current ratings. The PG-DSO-8 package is common across this family, offering consistent mechanical dimensions for design flexibility.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes must match the -20 V rating, PG-DSO-8 package, and P-channel polarity. Verify R_DS(on) and I_D specifications against original requirements. No other specific substitute part numbers are publicly confirmed for this exact model.
