概述

Description

MMBT2222A-TP is the SMD (SOT-23) version of the popular NPN transistor 2N2222A. It’s a general‑purpose transistor suitable for low‑ to medium‑current switching and amplification in surface‑mount designs. The “-TP” suffix typically indicates Tape‑and‑Reel packaging.
Key specs (typical, vary by manufacturer):
- Type: NPN BJT
- Vceo: up to about 40 V
- Ic: up to ~600 mA
- hFE: roughly 100–300 (depends on Ic and temperature)
- ft: tens to hundreds of MHz (high‑gain switching)
- Package/pinout: MMBT (SOT‑23), Pin 1 E, Pin 2 B, Pin 3 C (flat face toward you, leads down)
Common uses: general switching (relay/drain drivers), small‑signal amplification, level shifting in compact, surface‑mount circuits.
Note: exact numbers vary by vendor and lot; always consult the specific datasheet for Vceo, Ic, and hFE ranges for your part.

Features

Here are the key features of MMBT2222A-TP:
- General-purpose NPN transistor (silicon)
- Vceo: 40 V; Ic: up to 600 mA
- DC current gain (hFE): wide range, typically ~100–300 depending on Ic
- Low saturation voltage: Vce(sat) ≈ 0.3 V at Ic ≈ 150 mA ( Ib ≈ 15 mA)
- Package: SOT-23 (MMBT) with 3 leads
- Packaging variant: TP (Tape & Reel) for automated assembly
- RoHS-compliant / lead-free
- Temperature range: -55°C to +150°C
- Suitable for switching and amplification in low-power circuits
(Values are typical/range-based and may vary by lot/manufacturer.)

Package

MMBT2222A-TP is an MMBT (SOT-23, 3-pin) small-signal NPN transistor. The “-TP” suffix indicates Tape & Reel packaging.

Pinout

- Pin count: 3 (SOT-23 package)
- Function: General-purpose NPN transistor used for switching and amplification in low-power circuits (MMBT2222A-TP).

Manufacturer
