MMDT2222A-TP

Overview

The MMDT2222A-TP is a dual NPN small-signal bipolar junction transistor manufactured by Micro Commercial Components. It integrates two independent NPN transistors within a single SOT-363 surface-mount package. The device supports a maximum continuous collector current of 600 mA and withstands a collector-emitter voltage of 40 V. Key electrical characteristics include a collector-base voltage rating of 75 V, an emitter-base voltage limit of 6 V, and a transition frequency of 300 MHz. Thermal management allows for a power dissipation capacity of 150 mW, with an operational temperature range spanning from -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm compliance status and packaging type. Ensure that the procurement channel provides authentic components from Micro Commercial Components to avoid counterfeit risks. Cross-reference the datasheet revision date with the production batch to guarantee parameter consistency during integration.

Selection Notes

Select this component when space-constrained designs require dual NPN functionality without occupying separate board areas. Consider the 150 mW thermal limit and ensure adequate PCB copper area for heat dissipation. Verify that the required gain bandwidth product meets the circuit's frequency requirements before finalizing the design.
