Overview
The FMG11AT148 is a dual NPN pre-biased digital transistor from the ROHM FMG11A series, housed in an SMT5 (SC-74A) surface-mount package. It features a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The device integrates typical input resistors of 4.7kΩ with a power dissipation rating of 300mW. It supports a minimum DC current gain (hFE) of 100 at 1mA/5V and operates within a temperature range of -55°C to +150°C.
Feature Summary
- Dual NPN configuration integrated into a single compact surface-mount package
- Built-in base biasing network simplifies circuit design by reducing external component count
- High thermal stability supporting operation up to +150°C junction temperature
Applications
- General-purpose switching circuits requiring dual logic control
- Interface drivers for microcontroller output expansion
- Signal level shifting between different voltage domains
Procurement Notes
Verify component authenticity through authorized channels due to availability fluctuations. Confirm RoHS compliance status prior to integration. Ensure storage conditions maintain moisture sensitivity level integrity. Validate pinout alignment with PCB footprint specifications during assembly preparation.
Selection Notes
Select this component for applications requiring dual NPN switching with integrated biasing in minimal space. Consider the 50V voltage limit and 100mA current capacity against load requirements. Evaluate the SMT5 package dimensions for board real estate constraints compared to alternative discrete transistor solutions.
Part Context
Part of the ROHM FMG11A series of pre-biased transistors designed for high-density electronics. The series offers various resistor combinations to suit different drive requirements while maintaining consistent electrical characteristics across the family.
Replacement Considerations
FMG5AT148: Similar dual NPN configuration but utilizes 10kΩ input resistors instead of 4.7kΩ. Verify biasing current implications before substitution.
