CMPTA14 TR TIN/LEAD

Single Bipolar Transistors Overview

The CMPTA14 TR TIN/LEAD is a surface-mount NPN silicon Darlington transistor manufactured by Central Semiconductor Corp. It features a maximum collector-emitter voltage (VCEO) of 30 V and a continuous collector current (Ic) of 500 mA. The device operates within a junction temperature range of -65°C to +150°C and has a maximum power dissipation of 350 mW. Key electrical characteristics include a DC current gain (hFE) of at least 20,000 at 100 mA and 5 V, and a transition frequency (fT) of 125 MHz. The saturation voltage is specified as 1.5 V max at 100 µA base current and 100 mA collector current.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm lead-free status and packaging configuration. Confirm availability through authorized distributors as this item may be subject to special order requirements. Ensure the requested variant matches the exact pinout and electrical specifications required for the design.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is required in a small surface-mount footprint. Compare the 30 V rating and 500 mA current limit against circuit demands. Consider the SOT-23 thermal constraints for power dissipation calculations. Verify compatibility with existing PCB footprints and assembly processes for SMD components.

Single Bipolar Transistors Part Context

This part belongs to the CMPTA series of complementary silicon Darlington transistors from Central Semiconductor. It serves as the NPN counterpart in a matched pair configuration, often used alongside its PNP complement for push-pull output stages or differential amplifiers. The series is designed for general-purpose low-power switching and amplification tasks.

Single Bipolar Transistors Replacement Considerations

Direct equivalent replacements include the Nexperia PMBTA14 and Rohm Semiconductor variants. Verify that substitute parts meet the same 30 V, 500 mA, and SOT-23 package requirements before integration.
