IRF9540N P-Channel MOSFET TO-220 Packs and Assortments
Compare IRF9540N P-channel MOSFET packs, TO-220 model selectors and mixed transistor assortments. Product headings often list several part numbers, but a selectable “Color” value may determine the one model supplied. Read the selected part number and pack quantity together before buying; an assortment is different from a single-model pack.
Choose the correct listing
- IRF9540N single-model choices: several TO-220 listings offer an IRF9540N choice in a five- or ten-piece pack. One page offers 10 or 30 pieces under a shared IRF9540N/IRF9540 title, and other ten-piece fixed listings name both suffixes without a separate model selector. When a suffix matters, confirm the actual device marking rather than assuming every shared title establishes the exact orderable code.
- Other choices on shared pages: IRF9520N, IRF9530N, IRF4905 and IRF9Z24N appear alongside IRF9540N on some menus. N-channel IRF520N, IRF530N, IRF540N, IRF630N, IRF640N, IRF3205 and others are separate devices, not IRF9540N replacements. A 10-piece page names IRF9540N in its headline but offers only IRF9540 without the N as the purchasable choice. Check the selected option, polarity and datasheet.
- Mixed sets: 50-piece multi-model TO-220 kits and a 60-piece 12-value assortment name IRF9540N among other MOSFETs. Their stated total is not the quantity of IRF9540N alone. Verify the per-model breakdown and package contents on the individual listing; do not apply any one model's rating to all parts in a set.
- Different device and package choices: one five-piece selector also offers IRLR3110Z and IRLZ24N, a BTB12-600BW triac and 7805-family voltage-regulator options. The triac and regulators are different component classes. The IRF9540NS option on a separate page is explicitly TO-263 surface mount, not IRF9540N TO-220; IRF9530NS is another distinct choice.
Electrical and ordering checks
IRF9540N is a P-channel selection. Match the full part-number suffix, case style, pinout, drain-source and gate-source limits, on-resistance at the real gate drive, gate charge, safe operating area and thermal mounting to the design using a confirmed datasheet. A headline such as 23 A or 100 V does not establish continuous current capability in your assembled circuit. Gate-threshold voltage is not a guarantee of low-loss operation. One listing says TO-220 in its title but SOP in its specifications, so confirm the actual package before purchase. Seller originality and certification language is not independently verified across this collection.
Frequently asked questions
Does a ten-piece model selector contain every part named in the title?
No. The chosen model is the ordering choice for that pack; multiple names in the heading do not make it a mixed kit.
Does a 50-piece kit contain 50 IRF9540N devices?
No such conclusion follows from the total. These are described as multi-model assortments; check the number of each type in the selected kit.
Can IRF9540NS replace IRF9540N on the same PCB footprint?
Do not assume so. The IRF9540NS choice here is TO-263 surface mount while the IRF9540N choices are presented as TO-220 through-hole. Compare datasheets, pinout and thermal design.
Are IRF540N and IRF3205 alternative P-channel parts?
No. They appear as N-channel options on shared pages, and must be evaluated for a different circuit role rather than substituted by package similarity.
