Product Overview
Four 2222A-Class Switches In One 16-Lead Footprint
Condition
Condition is New, and the photographed piece is representative of our stock of twenty. The camera shows a black molded 16-lead surface-mount body with eight gull-wing leads per side, all of them bright and evenly formed with no bends or damage visible in these photos. The top surface carries a clean marking that reads MMPQ2222A over the Motorola M logo and the code XXAA625, with a pin-1 bar at the left end of the marking. Both photos show the same face of the part, so the underside is not pictured.

Product Overview
The Motorola MMPQ2222A packs four independent NPN bipolar transistors into a single 16-lead small-outline surface-mount package, the part our original catalog copy described as Multi-Chip General Purpose SOP16 and which is commonly cataloged as SOIC-16. The devices belong to the 2N2222A class, the general purpose NPN switching transistor that has been the default answer for small-signal switching and low-power driver stages since the discrete era. Putting four of them behind one set of gull-wing leads is a board-space decision: a designer who needs a bank of switches for relay drivers, LED strings, level shifting, or logic interface gets one placement and one reflow instead of four. The photographed piece is marked MMPQ2222A with the Motorola logo and the lot code XXAA625. Exact voltage, current, gain grouping, and power dissipation figures are not confirmed here, so verify them against the MMPQ2222A datasheet before you commit the part to a design. Sold each, from a stock of twenty.
Key Features
- Four independent NPN general purpose transistors in one package
- 2N2222A-class small-signal switching devices
- 16-lead small-outline surface-mount body, eight gull-wing leads per side
- Pin-1 bar marked at the left end of the top marking
- Photographed piece marked MMPQ2222A with the Motorola M logo and lot code XXAA625
- Leads bright and evenly formed in the photos, no bends visible
- Electrical ratings not confirmed here - verify against the MMPQ2222A datasheet before use
Applications
- A repair tech reworking a legacy control board that came with a quad array in this footprint and needs the same device number back in place
- A designer building a bank of low-side switches or relay drivers who wants one placement instead of four discrete transistors
- A prototype builder laying out a dense surface-mount board where four separate SOT packages will not fit
- An instructor or lab stocking a drawer of surface-mount practice parts with real markings and real leads
Frequently Asked Questions
What exactly is printed on the part?
The photographed piece reads MMPQ2222A on the first line, then the Motorola M logo followed by XXAA625 on the second line, with a pin-1 bar at the left. That is the full extent of the marking on the face the photos show.
Is XXAA625 the number I should order by?
No. XXAA625 is a lot and assembly code, not a device number. MMPQ2222A is the part number, and that is what we have listed it under.
What are the voltage and current ratings?
We are not publishing figures we have not confirmed. The devices are 2N2222A-class general purpose NPN switches, and the per-device breakdown voltage, continuous collector current, gain grouping, and package power dissipation should be read off the MMPQ2222A datasheet before use.
Will my piece carry the same lot code as the one in the photos?
We cannot promise that. The photographed part is representative of the stock, and the marking shown is the spec for that piece only. If a specific lot code matters to your build, ask us before ordering and we will look at what is on the shelf.
Why buy a few here instead of a bag of a hundred somewhere else?
Because most people who need this part need one or two, not a reel. A quad array goes into one spot on one board, and paying for ninety-eight spares to get the two you need is how drawers fill up with parts nobody ever touches again. We have twenty on the shelf and you take the count you actually need. Shipping is a flat $8, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
The 2222A spent decades as the transistor everyone reached for, and Motorola's answer to needing four at once was to stop counting them out and mold them into one body. One footprint, four switches, and your board gets its afternoon back.
