IRF4905 P-Channel MOSFET TO-220 and TO-263 Options
Compare IRF4905 P-channel power MOSFET listings in TO-220 through-hole format and IRF4905S surface-mount TO-263 format. This collection contains fixed ten-piece packs, quantity-selectable IRF4905S packs and shared model selectors. A long heading can name many devices: the selected option, not every model in the heading, is what a single-model pack offers.
Package and pack choices
- IRF4905 TO-220: dedicated ten-piece listings name IRF4905 and IRF4905PBF in the headline. Several shared TO-220 pages provide an IRF4905 model choice in five-, ten- or twenty-piece packs. On these menus, “Color” is usually the model selector. Choose IRF4905 explicitly; selecting IRF3205, IRF540N, IRF1404 or another named model does not order IRF4905.
- IRF4905S TO-263: a quantity selector lists 10, 20 or 30 pieces under an IRF4905S heading; another fixed ten-piece listing names IRF4905S/IRF4905STRPBF. A shared SMD page has the explicit option “10PCS IRF4905S TO263” alongside other TO-252 and TO-263 models. Its option field is labelled “Voltage” but actually encodes model, quantity and package. One IRF4905S listing calls its package through-hole in the specifications despite a TO-263 SMD title; confirm the physical case before ordering.
- Mixed-polarity model pages: IRF4905, IRF9540/IRF9540N and IRF9Z24N appear with many N-channel options on shared pages, including IRF3205, IRF3710, IRF530, IRF540, IRF640 and IRFB4110. These pages offer the selected model as a pack rather than all listed types as a kit. One page describes itself as N-CH even though it includes an IRF4905 choice; check polarity at the variant level.
Selection and compatibility
IRF4905 is a P-channel choice, so compare circuit polarity and gate-drive requirements with the full datasheet for the exact supplied suffix. Match drain-source and gate-source limits, on-resistance at the available gate voltage, gate charge, safe operating area, pin arrangement and thermal mounting. TO-220 IRF4905 and TO-263 IRF4905S are different packages and are not drop-in footprint substitutes. The 55 V, 74 A and 200 W figures in seller headlines are device-level claims under particular test conditions, not guarantees of continuous capability on an assembled board. Claims of originality or certification on individual pages are not independently verified for the collection.
Frequently asked questions
Does a ten-piece listing with many model names contain ten of each?
No. In the model-selector listings, the selected option identifies a single part number for the stated pack quantity. Read the exact variant before checkout.
Can IRF4905S replace an IRF4905 TO-220 part?
Not on the same board footprint without redesign. The listings identify IRF4905S as TO-263 SMD and IRF4905 as TO-220 through-hole; verify pinout and thermal path as well as electrical characteristics.
Is an IRF3205 option another IRF4905?
No. It is a different model on a shared listing, and channel polarity and circuit behavior must be checked separately.
Does the “Voltage” option always specify a voltage rating?
No. On one SMD listing it contains a part number, pack count and case style. Do not interpret its label as a universal rating.
