After that window closes, the only channel is surplus and broker inventory. If this part is on your active BOM, the decision is whether to secure a last-time-buy quantity for the product's remaining life or to qualify a pin-compatible replacement before the window shuts. ## Package and mounting — through-hole TO-262 The TO-262-3 (I²Pak, TO-262AA) is a through-hole package with long leads, designed for board mounting where the tab is soldered to a PCB pad or clamped to a heatsink. The through-hole format is preferred in high-vibration environments and for prototyping, though it takes more board area than a surface-mount D²Pak.","metaTitle":"IRFZ44ZLPBF HEXFET N-Channel MOSFET, 55V, 13.9mOhm, TO-262","metaDescription":"IRFZ44ZLPBF HEXFET N-Channel MOSFET, 55V Vdss, 51A Id, 13.9mOhm Rds(on) at 10V.
