CMLT2222AG TR PBFREE

Overview

The CMLT2222AG is a surface mount silicon dual NPN transistor manufactured by Central Semiconductor Corp. It consists of two isolated 2222A NPN transistors in an SOT-563 package, designed for small signal general purpose and switching applications. Key electrical ratings include a collector-base voltage (V_CBO) of 75 V, collector-emitter voltage (V_CEO) of 40 V, emitter-base voltage (V_EBO) of 6.0 V, and continuous collector current (I_C) of 600 mA. Power dissipation ranges from 150 mW to 350 mW depending on the PCB mounting pad area. The device operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Dual configuration with two electrically isolated NPN transistors integrated into a single compact surface mount package.

Applications

• Small signal general purpose amplification
• Electronic switching circuits

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The 'PBFREE' suffix indicates lead-free plating options as defined by the manufacturer's standard terms. Confirm that the requested component matches the exact datasheet specifications and environmental compliance requirements required for the intended design implementation.

Selection Notes

Select this component when a dual NPN configuration is required in a space-constrained surface mount layout. Evaluate thermal resistance and power dissipation limits based on the specific copper mounting pad area used in the PCB design. Ensure the operating environment stays within the specified -65°C to +150°C junction temperature range for reliable performance.

Part Context

This part belongs to the 2222A series of NPN silicon transistors. It is functionally equivalent to the widely used 2N2222A but packaged for surface mount technology. The dual configuration allows designers to utilize two matched transistors in a single footprint, simplifying board layout for complementary or differential circuit topologies.

Replacement Considerations

Direct pin-compatible replacements may exist from other manufacturers offering dual NPN transistors in the SOT-563 package. Verify that substitute components meet the same voltage, current, and thermal ratings. Check for differences in hFE gain bands and switching times to ensure compatibility with the original circuit design constraints.
