FMC6AT148

Overview

The FMC6AT148 is a dual pre-biased transistor array manufactured by ROHM Semiconductor, housed in an SMT-5 (SC-74A/SOT-753) surface-mount package. It integrates one NPN and one PNP bipolar junction transistor with built-in biasing resistors. The device supports a maximum collector-emitter voltage of 50V for both polarities and a continuous collector current of 100mA. Key electrical parameters include a DC current gain (hFE) minimum of 68 at 5mA/5V for the NPN section and a transition frequency of 250MHz. Power dissipation is rated at 300mW, with a maximum operating temperature of +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors with internal base and emitter resistors to simplify circuit design.
• Provides high-speed switching capabilities with a transition frequency of 250MHz.
• Offers compact surface-mount packaging suitable for automated assembly processes.

Applications

• General-purpose signal switching in consumer electronics
• Driver circuits for low-power loads requiring complementary logic levels
• Interface applications between microcontrollers and peripheral devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes against official datasheets. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain reliability prior to soldering.

Selection Notes

Select this component when space-constrained designs require matched NPN/PNP pairs with integrated biasing. Evaluate thermal management needs against the 300mW power dissipation limit. Compare input resistance values and saturation voltages against specific logic family requirements to ensure compatibility.

Part Context

This part belongs to the FMG/FMC series of digital transistors from ROHM Semiconductor. These components are designed to replace discrete resistor-transistor networks, reducing board space and assembly costs. The series is widely used in portable devices and industrial control systems where reliable switching is critical.

Replacement Considerations

Cross-reference with FMG5AT148 for single-polarity alternatives or other SMT-5 packaged dual arrays. Verify pinout compatibility and electrical parameter overlaps before substitution. Consult official replacement lists for lifecycle status updates.
