FMB2222A

Overview

The FMB2222A is an NPN multi-chip general-purpose amplifier manufactured by onsemi. It integrates four discrete transistors within a single SuperSOT-6 package to provide high current handling and low saturation voltage. The device supports continuous collector currents up to 500 mA with a collector-emitter breakdown voltage of 45 V and a collector-base voltage of 75 V. Total power dissipation reaches 700 mW, while the transition frequency is rated at 300 MHz. Designed for medium-power amplification and switching applications, it operates across a junction temperature range from -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the component meets all applicable RoHS directives and environmental compliance standards required for the target assembly process. Ensure the selected packaging format aligns with automated placement equipment specifications.

Selection Notes

Select this component when circuit designs require multiple matched NPN transistors in a minimal footprint. Evaluate thermal resistance characteristics to ensure adequate heat dissipation under maximum load conditions. Compare total power dissipation limits against ambient operating temperatures to maintain safe junction temperatures during continuous operation.
