CMKT5087 TR PBFREE

Overview

The CMKT5087 TR PBFREE is a dual silicon transistor array manufactured by Central Semiconductor Corp, housed in an SOT-363 ULTRAmini™ surface-mount package. It contains two single PNP transistors designed for high gain and low noise applications. Key electrical ratings include a collector-base voltage of 50 V, a collector-emitter voltage of 50 V, and an emitter-base voltage of 3.0 V. The device supports a continuous collector current of 50 mA with a power dissipation of 350 mW. DC current gain ranges from 250 to 800 at IC=0.1mA, and the transition frequency is 40 MHz.

Feature Summary

• Space-saving SOT-363 ULTRAmini™ package design
• Dual PNP transistors integrated into a single component
• Optimized for high gain and low noise performance

Applications

• High-gain amplifier circuits
• Low-noise signal processing stages
• Compact surface-mount electronic designs

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation before procurement. The PBFREE designation indicates lead-free plating compliance. Confirm that the required plating option matches the project specifications, as alternative plating options may require different suffixes. Ensure the package type and pin configuration align with the intended PCB layout.

Selection Notes

Select this component when a compact dual PNP solution is required for space-constrained designs. The SOT-363 package offers a smaller footprint compared to discrete components. Consider the 50 V voltage rating and 50 mA current limit for circuit compatibility. Evaluate the thermal resistance and power dissipation characteristics relative to the expected operating conditions.

Part Context

This part belongs to the CMKT50xx series of surface mount dual silicon transistors. The series includes complementary configurations such as the CMKT5078 (NPN/PNP) and the CMKT5088 (NPN/NPN). All variants share the same physical package dimensions and pinout structure, differing only in the internal transistor polarities.

Replacement Considerations

Direct substitutes within the same series include the CMKT5078 and CMKT5088, provided the circuit topology accommodates NPN or complementary transistor types instead of the dual PNP configuration of the CMKT5087.
