The SMBT2227A-TP is a small signal surface mount transistor pair manufactured by Micro Commercial Components (MCC). It integrates an NPN 2N2222A and a PNP 2N2907A in a single SOT23-6L package. The NPN section supports a collector current of 0.6 A, a collector-emitter voltage of 40 V, and a transition frequency of 300 MHz. The complementary PNP section provides a collector current of -0.6 A, a collector-emitter voltage of -60 V, and a transition frequency of 200 MHz. Total device power dissipation is rated at 700 mW.
Verify the specific ordering suffix when purchasing components. The standard part number includes a -TP suffix indicating tape and reel packaging. An additional -HF suffix designates halogen-free variants. Confirm that the received devices match the required environmental specifications before integration into production lines.
Select this component when a matched NPN/PNP pair is required in a compact footprint. Ensure the application voltage does not exceed the 40 V rating for the NPN side or -60 V for the PNP side. Verify that the total power dissipation requirements remain within the 700 mW limit under expected ambient temperature conditions.
This component belongs to the SMBT series of dual transistors from Micro Commercial Components. It serves as a compact alternative to discrete transistor pairs, saving board space in designs requiring complementary logic or push-pull configurations. The SOT23-6L package facilitates automated surface mount assembly processes.
Direct replacements must maintain the SOT23-6L package and matching NPN/PNP electrical characteristics. Verify pinout compatibility and ensure the substitute parts meet the same voltage and current ratings specified in the datasheet.
