FMG5AT148

Overview

The FMG5AT148 is a dual NPN digital transistor from the ROHM FMG5A series, housed in an SMT-5 (SC-74A) surface-mount package. It integrates two common-emitter transistors with built-in bias resistors, featuring a typical input resistance of 10 kOhms and a resistor ratio of 4.7. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 300 mW, with a minimum DC current gain (hFE) of 68. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Integrates dual NPN transistors with pre-biased resistors to simplify circuit design.
• Utilizes compact SMT-5 surface-mount packaging for efficient board space utilization.
• Provides high thermal stability with an extended operating temperature range up to 150°C.

Applications

• General-purpose switching circuits requiring dual NPN logic interfaces.
• Driver stages for small-signal loads in consumer electronics.
• Level shifting applications in embedded systems.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation before integration. Check for end-of-life notifications, as this part may be marked as Not Recommended for New Designs (NRND). Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to prevent package damage during soldering.

Selection Notes

Select the FMG5AT148 when a dual NPN configuration with integrated biasing is required in a compact footprint. Compare the 10 kOhm input resistance against other series variants like the FMG3AT148 if different drive characteristics are needed. Verify that the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This component belongs to the ROHM FMG5A series of digital transistors. It shares the SC-74A package form factor with related parts such as the FMG8AT148 but differs in internal resistor ratios and gain specifications. The series is designed for applications needing multiple discrete transistors replaced by a single integrated solution.
