FMC5AT148

Overview

The FMC5AT148 is a dual digital transistor from ROHM Semiconductor, integrating one NPN and one PNP bipolar junction transistor within a single SC-74A (SOT-753) surface-mount package. This component operates with a maximum collector-emitter voltage of 50 V and supports a continuous collector current of 100 mA. It features an integrated power dissipation rating of 300 mW and functions reliably across an operating temperature range from -55°C to +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors in a single compact package
• Includes built-in bias resistors to simplify circuit design
• Supports high-temperature operation up to 150°C

Applications

• General-purpose switching circuits requiring mixed polarity control
• Logic level translation interfaces
• Driver stages for low-power loads

Procurement Notes

Verify the specific datasheet version and electrical characteristics directly from ROHM Semiconductor before integration. Confirm that the SC-74A footprint matches your PCB layout requirements. Ensure thermal management strategies account for the 300 mW power dissipation limit under expected load conditions to maintain reliability.

Selection Notes

Select this component when space-constrained designs require both NPN and PNP switching capabilities. The integrated resistor network reduces external component count compared to discrete solutions. Verify that the 50 V voltage rating and 100 mA current capacity align with the target application's electrical demands.

Part Context

This device belongs to ROHM’s pre-biased transistor array family, designed to replace multiple discrete components. The FMC5AT148 specifically combines NPN and PNP structures, offering a versatile solution for applications needing complementary switching actions within a minimal footprint.

Replacement Considerations

FMG5AT148: Dual NPN configuration only; not electrically equivalent for mixed-polarity needs. FMA5AT148: Dual PNP configuration only; unsuitable for NPN requirements.
