Product Overview
The 2N3906 is the PNP half of the 2N3904/2N3906 general purpose amplifier and switch pair, a TO-92 part rated 40 V and 200 mA (onsemi's published 2N3906 data).
32 are on the shelf, sold each. The representative unit photographed is a black TO-92 with a flat marked face and a rounded back, lettered in three lines: 2N on the top line, 3906 under it, and the Motorola batwing followed by 507 at the bottom. That 507 is the marking string on this particular holding, and it stays a string - the published data behind this page decodes nothing about these codes, so no date is claimed from it. The three leads leave the body straight and parallel, at full length, untrimmed and unbent, and photograph a bright grey against the dark speckled backdrop.
Key Features
- Polarity: PNP silicon general purpose amplifier and switch
- VCEO: -40 V; VCBO -40 V; VEBO -5 V (per onsemi's published 2N3906 data)
- IC: -200 mA (per onsemi)
- PD: 625 mW at TA = 25 degC (per onsemi)
- fT: 250 MHz minimum (per onsemi)
- hFE: 100 to 300 at IC = 10 mA (per onsemi)
- Package: TO-92 plastic (TO-226AA), three leads, through-hole mount
- Complement: 2N3904, the NPN of the pair (per onsemi)
- Body marking on the unit photographed: 2N, 3906, Motorola batwing, 507
- We quote no lead order for this package, because the data we work from does not publish one; confirm the pinout against onsemi's published 2N3906 data before you solder
- Verify against onsemi's published 2N3906 data before designing in.
Applications
- Small signal PNP switching on logic-level drive
- High-side switch for a low current load
- General purpose audio and instrumentation preamp stages
- Breadboard and classroom work on TO-92 footprints
Frequently Asked Questions
How many should I order?
Order the count the build needs. 32 are here, sold one at a time rather than as a taped strip or a bagged pack, so if a board wants four and your drawer wants a dozen, put all sixteen on the one order. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Which lead is which on this TO-92?
Do not take it from us, and do not take it from the shape of the body either. The published 2N3906 data behind this page gives the ratings but no lead assignment we can quote, and TO-92 pin order is not standard across part numbers - the flat face tells you which way the part is turned, not which lead is the base. Check onsemi's published 2N3906 data, or ring the junctions out with a meter's diode range before you commit the part to a board. The unit photographed has all three leads at full length and untrimmed, so you have room to bend them into whatever footprint you have.
A grain of black plastic marked 2N 3906, the part that has been standing in for the PNP side of everything since before most of the boards it fixes were drawn.
