CMLT2907A BK PBFREE

Overview

The Central Semiconductor CMLT2907A is a surface mount silicon dual PNP transistor consisting of two isolated transistors in an SOT-563 package. It features a collector-base voltage (V_CBO) and collector-emitter voltage (V_CEO) of 60 V, with an emitter-base voltage (V_EBO) of 5.0 V. The continuous collector current (I_C) is rated at 600 mA per transistor, and power dissipation (P_D) reaches 350 mW. Operating junction temperature ranges from -65 to +150 °C. DC current gain (h_FE) varies from 50 to 300 depending on collector current. Transition frequency (f_T) is 200 MHz.

Feature Summary

• Dual configuration with two electrically isolated PNP transistors within a single SOT-563 package
• Designed for small signal general purpose and switching applications
• Manufactured using epitaxial planar process technology

Applications

• Small signal amplification circuits
• General purpose switching applications
• Low power electronic designs requiring dual PNP functionality

Procurement Notes

Verify the specific ordering suffix when purchasing. The datasheet indicates that adding "PBFREE" specifies lead-free plating, while "TIN/LEAD" requests tin/lead plating options. Confirm package type and marking code L07 match design requirements before finalizing orders.

Selection Notes

Select this component when a dual PNP configuration is required in a compact SOT-563 footprint. Ensure the 60 V voltage rating and 600 mA current capacity meet circuit demands. Consider the 350 mW power dissipation limit and thermal resistance of 357 °C/W for adequate heat management in the application environment.

Part Context

This device belongs to the 2907A series of PNP transistors. It provides a dual-transistor alternative to single units, saving board space. The SOT-563 package allows for automated surface mount assembly. It serves as a compact solution for designs needing two matched or independent PNP switches.

Replacement Considerations

Direct replacements must be dual PNP transistors in SOT-563 packages. Verify pinout compatibility, specifically the arrangement of emitters, bases, and collectors for both Q1 and Q2. Check that voltage ratings and current capabilities are equal or superior.
