Single FETs, MOSFETs Procurement Notes

Verify the current lifecycle status before procurement as the component may be obsolete or nearing end-of-life. Confirm that the TO-3PN-3 through-hole package aligns with existing board designs. Ensure compatibility with required thermal management solutions given the 290W dissipation rating. Check for updated datasheets reflecting any final manufacturing changes prior to integration into new production runs.

Single FETs, MOSFETs Selection Notes

Select this component when a high-voltage, high-current discrete solution is required in a through-hole format. The 300V rating suits medium-voltage DC bus applications. Consider the 85mΩ on-resistance for efficiency requirements. Evaluate the thermal resistance characteristics against the expected ambient conditions. Compare against surface-mount alternatives if space constraints exist, though this part is specific to leaded mounting.
