Procurement Notes

Verify the specific suffix TWG against official onsemi documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact temperature grade and package variant required for your design. Cross-reference the datasheet revision history for any recent pinout or electrical characteristic updates before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel high-side switch with integrated protection is required for 24 V systems. Consider the 13.5 mΩ on-resistance for thermal management calculations under full load conditions. Verify that the 3 V to 5.5 V control voltage range aligns with your microcontroller or logic interface capabilities. Evaluate the DFN-10 package size constraints against your PCB layout requirements.
