CMLT2222AG BK 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 parameters include a collector-base voltage (V_CBO) of 75 V, collector-emitter voltage (V_CEO) of 40 V, and emitter-base voltage (V_EBO) of 6.0 V. The continuous collector current is rated at 600 mA with power dissipation ranging 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 containing two isolated NPN transistors within a single compact surface mount package.

Applications

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The provided model includes the PBFREE designation, indicating lead-free plating compliance as per manufacturer standards. Confirm availability through authorized distributors or direct manufacturer channels, as supply status may vary. Ensure the requested variant matches the exact marking code and package outline specified in the datasheet.

Selection Notes

Select this component when a dual NPN configuration is required in a surface mount format. Evaluate thermal resistance and power dissipation limits based on the specific copper mounting pad area used in the design. Consider the transition frequencies and gain bandwidth for high-speed switching requirements. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the 2222A series of NPN silicon transistors. It is functionally related to other variants such as the CMLT2222A and CMLT2222AG, which share similar electrical characteristics but may differ in packaging or plating options. The SOT-563 package allows for space-efficient designs compared to through-hole alternatives.

Replacement Considerations

Direct substitutes include parts with identical pinouts and electrical ratings, such as the CMKT2222A or other dual NPN transistors in SOT-563 packages. Verify compatibility regarding maximum ratings and thermal performance before substitution.
