Product Overview
The IRFZ44N is an N-Channel enhancement-mode power MOSFET in a TO-220 package, optimized for low on-state resistance and fast switching. It is ideal for DC motor drives, inverters, and switched-mode power supplies. Key Features: - V_DS: 55V, I_D: 49A (continuous) - R_DS(on) max: 17.5mΩ at V_GS = 10V - Gate threshold voltage: 2–4V - Package: TO-220 through-hole - Low gate charge for fast switching - Avalanche-rated for rugged operation
Procurement Notes
Use this page as a sourcing reference. Final availability, MOQ, lead time, and compliance assumptions should be confirmed through RFQ before ordering this part.
Substitute Selection Notes
When the original MPN is constrained, compare package, ratings, tolerance, temperature range, and compliance status before approving an alternate.
Typical Use Cases
Suitable for BOM review, maintenance sourcing, prototype replenishment, production-gap purchasing, and alternative-part screening.
