Description
MMBT2222A-TP is the surface-mount (SOT-23) version of the common 2N2222A general‑purpose NPN transistor. It’s used for low‑power switching and amplification in SMT boards.
Key points:
- Type: NPN BJT, small-signal/general purpose
- Vceo: typically 40 V
- Ic: up to about 600 mA
- Gain (hFE): roughly 100–300 (vary with Ic and temperature)
- Package/pinout: SOT‑23, usually E-B-C (pins 1–2–3)
- -TP: Tape-and-Reel packaging for automated assembly
- Applications: switching, buffering, amplification on SMT boards
- Note: Check exact datasheet for pinout, hFE range, and power dissipation for your lot.
Common replacement for through‑hole 2N2222A when SMT is required.
