CMLT8099 TR PBFREE

Overview

The CMLT8099 TR PBFREE is a surface mount silicon dual NPN transistor manufactured by Central Semiconductor Corp. It consists of two isolated transistors in an SOT-563 package, designed for small signal general purpose amplifier applications. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V and a continuous collector current (IC) of 500 mA per device. The power dissipation is rated at 350 mW with a thermal resistance (ΘJA) of 357 °C/W. Transition frequency (fT) reaches 150 MHz at IC=10mA, while DC current gain (hFE) ranges from 100 to 300 at IC=1.0mA.

Feature Summary

• Dual configuration containing two individually isolated NPN transistors within a single compact surface mount package.
• Designed specifically for small signal general purpose amplifier applications utilizing epitaxial planar process technology.
• Halogen-free construction compliant with environmental design standards.

Applications

• Small signal general purpose amplifiers

Procurement Notes

Verify the specific ordering suffix when purchasing. The 'PBFREE' designation indicates lead-free plating options as defined by the manufacturer's standard terms. Confirm that the required plating matches the project specifications before finalizing orders. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability according to Central Semiconductor Corp guidelines.

Selection Notes

Select this component when a dual NPN configuration is required in a space-constrained SOT-563 footprint. The 80 V collector-emitter voltage and 500 mA current rating suit low-power switching and amplification tasks. Consider the 357 °C/W thermal resistance for heat dissipation planning in dense PCB layouts. Verify that the hFE range of 100 to 300 meets the gain requirements of the target circuit design.

Part Context

This part belongs to the Central Semiconductor surface mount transistor family. It utilizes the SOT-563 case outline, which provides six pins for two independent devices. The marking code 'C89' identifies the unit on the package. It shares functional similarities with other dual transistor series but offers specific isolation characteristics between the internal elements.

Replacement Considerations

Direct substitutes must match the SOT-563 package, dual NPN topology, and 80V/500mA ratings. Verify pinout compatibility, specifically the emitter-base-collector arrangement for Q1 and Q2. Check if alternative manufacturers offer equivalent hFE and fT specifications for the same operating conditions.
