CMLT5078E TR PBFREE

Overview

The CMLT5078E TR PBFREE is a surface-mount silicon dual transistor manufactured by Central Semiconductor Corp. It features two PNP transistors in an SOT-563 package. Key electrical parameters include a collector-emitter breakdown voltage of 50V and a maximum continuous collector current of 100mA. The device has a transition frequency of 100MHz and a maximum power dissipation of 350mW. DC current gain is specified at a minimum of 300 at 100µA and 5V. The saturation voltage is 400mV at 10mA base and 100mA collector currents. Operating temperature ranges from -65°C to +150°C.

Feature Summary

• Dual PNP configuration within a compact SOT-563 surface-mount footprint
• High DC current gain suitable for low-current switching applications
• Wide operating temperature range for industrial environments

Applications

• Low-power signal switching circuits
• Logic interface stages
• General-purpose amplification

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and lead-free status. Confirm RoHS compliance requirements with the supplier prior to purchase. Check for any recent product change notices that may affect pinout or electrical characteristics. Ensure the component matches the required SOT-563 package dimensions for PCB layout compatibility.

Selection Notes

Select this component when a dual PNP transistor array is required in a small surface-mount package. Compare the 100mA collector current limit and 50V breakdown voltage against circuit demands. Evaluate the 350mW power dissipation capability relative to thermal constraints. Consider the 100MHz transition frequency for high-speed switching needs compared to slower alternatives.

Part Context

This part belongs to Central Semiconductor's line of surface-mount silicon dual transistors. It is designed as a space-saving alternative to discrete single transistors. The SOT-563 package allows for automated assembly and reduced board area. It serves as a complementary device in mixed-signal designs requiring matched PNP pairs.

Replacement Considerations

Potential substitutes include other dual PNP transistors in SOT-563 packages such as the CMKT5087 series, provided electrical parameters match. Verify pinout compatibility before substitution. Ensure replacement parts meet the same voltage and current ratings.
