FMG2AT148

Overview

The FMG2AT148 is a dual NPN digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications. It integrates two NPN transistors with built-in bias resistors in a compact SMT-5 (SOT-753) package. The device features a collector-emitter voltage rating of 50 V and a continuous collector current capacity of 100 mA. Key electrical parameters include a typical base resistor value of 4.7 kOhms and a minimum DC current gain (hFE) of 68. The component supports a maximum power dissipation of 300 mW and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to simplify circuit design.

Applications

• General-purpose switching circuits requiring compact dual-transistor solutions.

Procurement Notes

Verify the specific suffix T148 against official ROHM documentation to confirm packaging details and marking codes. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the sourcing channel provides valid traceability for this discrete semiconductor component prior to acquisition.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a small outline package. Verify that the 50 V collector-emitter voltage and 100 mA current ratings align with the target application's load requirements. Check that the 4.7 kOhm base resistance matches the driving interface specifications.

Part Context

This part belongs to the ROHM FMG series of pre-biased bipolar transistors. These devices are engineered to replace multiple discrete components, reducing board space and assembly complexity. The FMG2AT148 specifically utilizes the SMT-5 package format common in modern consumer electronics and industrial control modules.

Replacement Considerations

Consult ROHM's official cross-reference guides for verified substitutes. Generic equivalents may differ in hFE characteristics or internal resistor ratios. Validate pinout compatibility before substituting.
