2N3906 PNP Transistors and Mixed Transistor Assortments
Find 2N3906 PNP bipolar transistor choices for through-hole designs and MMBT3906 surface-mount alternatives, alongside mixed NPN/PNP transistor assortments. This collection includes individual model packs, selectable multi-model listings and prepacked kits. A product title mentioning 2N3906 does not guarantee that every variant or kit contains it.
Individual 2N3906 choices
- Through-hole 2N3906 options are labeled TO-92, commonly in 100-piece single-model selections; other shared pages list the exact selected transistor model with 100 or 1,000 pieces. A selection of 2N3904, 2N2222, 2N5401 or another model on those pages is not a 2N3906 pack.
- MMBT3906 is the SOT-23 surface-mount family appearing in separate 100-piece packs and a 3,000-piece listing. Shared SMD/DIP pages also let you choose MMBT3904 (NPN) versus MMBT3906 (PNP), or TO-92 versus SOT-23. Confirm package and exact selected device before specifying a PCB footprint.
- Some shared selections include 2N7000 or 2N7002 MOSFETs, TL431 reference devices and other NPN or PNP transistor types. These are distinct components, not 2N3906 substitutes.
Assortment kits
Many listings are TO-92 mixed kits rather than full packs of 2N3906. Examples include 10-value / 100-piece and 10-value / 200-piece sets, 18-value / 180-piece, 24-value / 480-piece, 15-value / 600-piece and 18-value / 900-piece configurations. Some choices vary between 50 and 840 pieces, 100 or 200 pieces with different box options, or named kit families. A 200-piece ten-value set listing 20 of each model contains 20 of its 2N3906 selection, not 200. Other named kit variants may omit 2N3906 altogether. Check each product's chosen variant and per-model packing list instead of inferring content from the shared title or total count.
How to choose
- Confirm PNP polarity and the precise 2N3906 or MMBT3906 model needed. 2N3904 and MMBT3904 are NPN devices, not drop-in PNP replacements.
- Check the manufacturer's datasheet for pin assignment, collector-emitter voltage, collector current, gain at your operating point, dissipation and temperature derating. Similar names do not establish identical package pinouts or ratings across suppliers.
- Match TO-92 through-hole or SOT-23 surface mount to the PCB footprint; a package change requires layout review.
- Determine whether the selected option is a single-model pack or an assortment, then verify total pieces and quantity per type. Generic “Color” and “Voltage” option names often denote model, kit contents or packaging rather than those physical properties. If descriptions and option labels conflict, confirm the selected packing list before ordering.
Frequently asked questions
Is MMBT3906 the same package as 2N3906?
No. Listings identify MMBT3906 as SOT-23 and 2N3906 through-hole options as TO-92. Compare the exact manufacturer's datasheets and pin assignments before changing footprints.
Do all assortment kits include 2N3906?
No such assumption is safe: the assortment menus include different named kit families and model-specific selections. Read the selected variant's model list and per-model count.
Is 2N3904 interchangeable with 2N3906?
No. 2N3904 is NPN and 2N3906 is PNP. Select based on the circuit and verify the full electrical and mechanical specifications.
Does “1000PCS” mean a thousand of every listed transistor?
No. On a single-model selection page the quantity applies to the chosen model, while an assortment's total is distributed among its listed types. Confirm the variant and packing details.
