Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'Z' against official manufacturer documentation to confirm lead-free status or tape-and-reel configuration. Ensure the component matches the exact SSOT-6 footprint and pinout specifications required for your PCB layout. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Single FETs, MOSFETs Selection Notes

Select this component when a compact P-channel switch is required for low-voltage applications. The 48 mΩ on-resistance offers efficiency benefits over higher resistance alternatives. Verify that the 20 V rating aligns with system voltage requirements and that the thermal dissipation capabilities suit the intended operating environment without excessive heatsinking.

Single FETs, MOSFETs Part Context

This part belongs to the FDC638P family of single P-channel MOSFETs. It shares core electrical specifications with variants differing primarily in packaging or reel configurations. The PowerTrench branding indicates adherence to onsemi's specific process technology for low Rds(on) performance in small outline packages.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes may include other 20 V P-channel MOSFETs in SSOT-6 packages with comparable Rds(on) and current ratings. Verify pin compatibility and thermal characteristics before substitution. Consult official cross-reference lists for confirmed equivalents.
