Product Overview
The PN2222A is the plastic TO-92 member of the 2222 switching family, an NPN general purpose part that has outlived most of the equipment it was designed into. The photographed piece has a pale blue-gray flat face on a black TO-92 body with three pale metal leads splayed out over a dark textured backdrop; the face reads PN2222A with PHI beside it, followed by a short two-character code that does not resolve in this frame. 19 of this part number are on the shelf, sold one at a time.
Key Features
- Type: NPN silicon switching and linear amplifier transistor
- Collector-emitter voltage: 40 V (V_CEO, per onsemi's published PN2222A data)
- Collector-base voltage: 75 V (V_CBO, per the same published data)
- Emitter-base voltage: 6 V (V_EBO, per the same published data)
- Collector current: 600 mA continuous, per the same published data
- Power dissipation: 625 mW, per the same published data
- Transition frequency: 300 MHz, per the same published data
- Package: TO-92 plastic, three leads, through-hole; this listing's own copy also gives the Philips package name SOT54
- Marking on the photographed body: PN2222A with PHI alongside
- Verify against onsemi's published PN2222A data before designing in.
Applications
- Low-side switching for relays, small LEDs and buzzers
- General purpose small-signal amplification
- Logic level buffering and inverter stages
- Through-hole board repair calling out a 2222A class NPN
Frequently Asked Questions
How many should I order?
Order the count the build needs. 19 of this part number are on the shelf, sold one at a time, which suits a repair and its spares rather than a production run. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
What is printed on the body?
The flat face carries PN2222A with PHI beside it, and after PHI a short two-character code that does not resolve in this photograph. PN2222A is the type; PHI is the maker abbreviation this listing already attributes to Philips. We quote the marking as far as it is legible rather than fill in characters the camera did not catch. If the trailing code matters to you, ask and we will look at a piece on the shelf before you order.
Three hundred megahertz and six hundred milliamps, out of a body the size of a lentil.
