P-Channel MOSFETs for High-Side Switch Design
Compare P-channel MOSFETs that may be considered for high-side switching, then validate the exact device and gate-drive circuit against its datasheet. The collection includes loose P-channel MOSFETs in SOT-23, SOP-8, TO-220 and TO-252 packages, but also N-channel models and driver ICs. A product's presence here is not proof that it is a ready-to-use high-side switch or compatible with your control voltage.
P-channel device choices
- Small surface-mount: the AO3400/AO3401/AO3402 SOT-23 selector offers AO3401 A19T as the P-channel choice; AO3400 A09T and AO3402 A29T are different selected devices. AO3401A is separately offered in a 100-piece SOT-23 listing, and JMTJ210P02A is a 100-piece SOT-23-3L listing. FDS4435BZ appears as a 10-piece SOP-8 listing. Compare full suffix and pinout, not just package family.
- Power packages: AP9435GH-HF, HY19P03D, AOD409 and selected 2SJ327/2SJ601/2SJ530 devices are described in TO-252 listings; NDP6020P is a TO-220 option with 10-, 20- or 30-piece choices. MTP2P50E is a through-hole listing with 10-, 20- or 30-piece lot choices. These parts differ in voltage class, on-resistance, drive requirements and thermal design.
- Different use case: ECX10P20 and ECX10N20 are separately selected TO-247 lateral audio MOSFETs. An audio-amplifier output-stage part should not be assumed equivalent to an ordinary high-side load switch.
Other products in the collection
TC4424CPA, TC4424EPA and TC426CPA are separately selectable DIP-8 MOSFET driver ICs in 10-piece choices, not bare P-channel transistors. The NCEP12T15 TO-220 page offers 10/20/30 pieces of its selected code; IXFH22N65X2/34N65X2/46N65X2/60N65X2/80N65X2 are five-piece TO-247 model choices. NCE0260/NCE0275/NCE1550/NCE7190/NCE82H140 are distinct TO-220 selections. IPB180N10S4-02 is explicitly an N-channel TO-263-7 device. Do not infer P-channel polarity or high-side suitability for any of these from the collection name.
How to assess high-side compatibility
For a P-channel high-side stage, gate-source voltage depends on the source potential. Check the gate driver's ability to establish the required negative VGS while remaining within the MOSFET's maximum VGS; a logic output referenced to ground is not by itself a complete compatibility test. Compare VDS margin, RDS(on) at the actual drive, gate charge, safe operating area, inductive-load behavior where relevant, heatsinking and package pin/tab connections. MOSFET driver ICs need their own output polarity, supply and control checks. Do not treat seller headline current, wattage, originality or certification claims as verified circuit ratings.
Frequently asked questions
Is every product here a P-channel high-side MOSFET?
No. N-channel devices, audio lateral MOSFET choices and DIP-8 driver ICs also appear. Read the selected variant and its datasheet.
Does the AO3400/AO3401/AO3402 page send three types in one pack?
No mixed pack is stated. Its selector chooses AO3401 A19T, AO3400 A09T or AO3402 A29T individually.
Will a 3.3 V controller directly turn on every high-side part?
Not necessarily. Check the available gate-to-source voltage at the actual source potential and on-resistance at that drive; use a suitable driver design where needed.
Are the 2SJ327, 2SJ601 and 2SJ530 options interchangeable?
No. They are separate selected models. Compare complete specifications, lead arrangement and package details before substituting.
