FMG6AT148

Overview

The FMG6AT148 is a dual NPN digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications. It features an integrated bias resistor network within a compact SMT-5 (SC-74A) package. The device supports a collector-emitter voltage of 50V and a continuous collector current of 100mA, with a power dissipation rating of 300mW. Key electrical parameters include a typical input resistance of 10 kOhms and a minimum DC current gain (hFE) of 80. The component operates across a temperature range from -55°C to +150°C, ensuring reliability in diverse electronic environments.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to simplify circuit design and reduce component count.
• Utilizes a small SMT-5 surface-mount package to facilitate high-density PCB layout and automated assembly.
• Provides stable switching performance with defined saturation voltages and high current gain characteristics.

Applications

• General-purpose signal switching and level shifting in consumer electronics.
• Driver circuits for low-power loads such as LEDs or relays in industrial control systems.
• Interface logic buffers between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific ordering suffix to confirm the exact tape-and-reel quantity and packaging configuration required for your production line. Confirm RoHS compliance status and check for any end-of-life notifications, as availability may vary based on manufacturing cycles. Ensure that the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a dual NPN configuration with fixed biasing is required to minimize external passive components. Compare the 10 kOhm input resistance against other variants in the FMG series if different base drive currents are needed. Verify that the 50V voltage rating and 100mA current capacity align with the maximum load requirements of the target application circuit.

Part Context

This part belongs to the ROHM FMG series of pre-biased transistors, which integrate internal resistors to replace discrete BJT and resistor combinations. The FMG6AT148 specifically denotes a dual NPN type with a 10 kOhm input resistance. It is part of a broader family offering various resistance ratios and configurations to suit different logic interface needs.

Replacement Considerations

Potential substitutes include other dual NPN digital transistors with similar 50V ratings and SMT-5 packaging. Verify pinout compatibility and electrical parameters such as hFE and Vce(sat) before substitution. Cross-reference with ROHM's internal replacement matrix for confirmed equivalent parts.
