SMD PNP Transistors and Mixed Surface-Mount Component Kits
Explore surface-mount PNP bipolar transistors for compact PCB designs, from small-signal SOT-23 parts to SOT-89, SOT-223 and TO-252 (DPAK) power-device options. This collection also contains multi-model listings with NPN choices, Darlington transistors, mixed SMD component books and a current-sense resistor listing. Selection is by the actual variant, not by the collection name or a multi-part product title.
Compare the PNP choices
- SOT-23 small-signal devices: listings include BC807-16 and BC807-40, BC857C, MMBT3906, MMBT4403, MMBT5401, MMBTA94, MMBT2907/MMBT2907A and S9015. The BC807 suffix denotes a device gain group, not a pack count. Some pages offer a single model and others offer NPN and PNP choices on the same page.
- Other surface-mount packages: options include SS8550, 2SA1797 and 2SB772 in SOT-89; PZT2907A, PBHV9215Z and CZT127 PNP Darlington in SOT-223; and 2SB1181, MJD42C and MJD45H11 in TO-252/DPAK. Package families and pin assignments are not interchangeable simply because the devices are PNP.
- Mixed-model selections: BCV26/BCV27/BCV46/BCV47, MMBT2222 versus MMBT2907, MMBT5551 versus MMBT5401, MJD41C versus MJD42C, and other MJD models share product pages. Read the chosen variant's model and polarity: an NPN choice does not become PNP because of this collection's name.
What a selected pack includes
Listings range from 10-, 20-, 50- and 100-piece selections to larger tape-and-reel choices labeled 2,500 or 3,000 pieces. These quantities apply only where stated for the selected option; a shared listing can change both model and count. An SMD assortment book uses choices such as 21, 36, 60, 75, 87 or 111 values at 25 or 50 pieces per value and may include transistors, diodes and TL431 devices. It is not a single-model PNP reel. One listing offers low-ohm 2512 current-sense resistors with resistance and power options; those are resistors, not transistors.
Selection checklist
- Identify the exact selected part number, polarity and transistor type. A Darlington device has different drive and saturation characteristics from a conventional single BJT.
- Match the actual package, pad layout, pinout and marking to the intended PCB footprint. Similar top markings are not sufficient identification on their own.
- Check the chosen manufacturer's datasheet for voltage, current, gain at the operating point, dissipation and thermal conditions. Do not treat mixed title ratings or contradictory option labels as specifications applying to every model.
- Confirm whether the variant is a single-model pack, a reel, or a multi-value kit; check its exact piece count and per-value contents. Options labeled “Color” or “Voltage” may instead select a model, quantity or kit configuration.
Frequently asked questions
Are all options here PNP transistors?
No. Some shared listings select NPN parts such as MMBT2222, MMBT5551, BCV variants or MJD41C, and the collection includes an assortment book and a resistor listing. Check the selected variant before ordering.
Can I replace a SOT-23 PNP with a SOT-89 or DPAK part?
Not as a drop-in replacement. Check electrical behavior, package dimensions, pad pattern, pin assignment and thermal design against both datasheets.
Does a “3000PCS” title guarantee 3,000 pieces of the selected PNP model?
Only when the chosen variant and its packing information agree. Some pages include NPN model choices, alternate quantities or conflicting rating text; verify the exact selected option.
What does BC807-16 versus BC807-40 mean?
The suffix identifies a gain-group designation, not 16 or 40 pieces. Confirm the gain range and test conditions in the selected manufacturer's datasheet.
