FMB2907A

Overview

The FMB2907A is a PNP silicon epitaxial planar transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. It is housed in the SOT-363 (SC-88) surface-mount package, which integrates two complementary transistors in a single compact form factor. The device features a maximum collector current of 600 mA and a collector-emitter voltage rating of 60 V. Key electrical parameters include a transition frequency of 200 MHz and a DC current gain minimum of 100. The component supports an operating temperature range from -55°C to +150°C with a total power dissipation of 225 mW.

Feature Summary

• Dual complementary configuration integrating PNP and NPN transistors in a single SOT-363 package
• High-speed switching capability supported by a 200 MHz transition frequency
• Robust thermal performance allowing operation up to 150°C junction temperature

Applications

• General-purpose signal switching circuits
• Linear amplifier stages requiring complementary pairs
• Digital logic interface and level shifting applications

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout orientation and electrical tolerances. Ensure the ordering part number matches the required SOT-363 variant. Confirm RoHS compliance status through the latest product change notification or datasheet revision history before finalizing procurement specifications.

Selection Notes

Select this component when space constraints necessitate a dual-transistor solution in a low-profile SMD package. The 60V rating suits moderate voltage switching tasks. Verify that the 600mA continuous current limit meets the load requirements. Consider the complementary nature of the internal structure if both PNP and NPN functions are needed within a single footprint.

Part Context

This component belongs to the 2N2907 family of PNP transistors, adapted for surface-mount technology. While the standard 2N2907 utilizes a TO-92 leaded package, the FMB2907A variant offers a miniaturized SOT-363 footprint. This evolution supports automated assembly processes and higher density PCB layouts compared to through-hole alternatives.

Replacement Considerations

Direct substitutes include the PMBT2907A in SOT-23 packages, though pinouts may differ. The MMBT2907ALT1G serves as a functional equivalent in SOT-23. For identical SOT-363 dual configurations, verify cross-reference data sheets for matching hFE bins and voltage ratings.
