Single FETs, MOSFETs Procurement Notes

Verify the exact suffix 'TU' against official Fairchild or onsemi documentation, as standard listings often reference 'SFP9630'. Confirm RoHS compliance status and lead times directly with authorized distributors, noting that this component may be classified as obsolete or not recommended for new designs. Ensure the package matches the required TO-220 form factor for your PCB layout.

Single FETs, MOSFETs Selection Notes

Select this component when a P-channel MOSFET with 200V rating and moderate current handling is required. Compare the 0.8 ohm maximum on-resistance against system efficiency targets. Consider the TO-220 package for through-hole mounting and heat sinking capabilities. Evaluate the avalanche energy rating if the application involves inductive loads prone to voltage spikes.

Single FETs, MOSFETs Part Context
