BC141-10

Single Bipolar Transistors Overview

The BC141-10 is an NPN silicon planar epitaxial transistor manufactured by STMicroelectronics, housed in a JEDEC TO-39 metal case. It is engineered for audio amplification and switching applications with a maximum collector current of 1 A. The device features a collector-emitter voltage rating of 40 V and a minimum DC current gain (hFE) of 63 to 100. It operates at a maximum junction temperature of 175 °C with a power dissipation of 0.75 W. The complementary PNP variant is the BC161.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as BC141-10 is produced by multiple vendors including STMicroelectronics, NXP, and others. Confirm that the TO-39 metal package matches your thermal and mechanical requirements. Ensure the hFE binning aligns with circuit design needs. Check terminal plating specifications if RoHS compliance or specific soldering processes are required for your assembly line.

Single Bipolar Transistors Selection Notes

Select this component when high current handling up to 1 A is required in a through-hole metal package. Consider the TO-39 form factor for superior heat dissipation compared to plastic packages. Verify compatibility with the BC161 PNP counterpart if push-pull configurations are needed. Ensure the 40 V voltage rating suits the load conditions.

Single Bipolar Transistors Part Context

The BC141 belongs to the general-purpose medium-power transistor family. It is widely recognized for its use in audio stages and low-frequency switching. The TO-39 metal case provides better thermal performance than standard plastic equivalents. Multiple manufacturers produce this part, ensuring broad availability across the industry.

Single Bipolar Transistors Replacement Considerations

The BC161 is the direct complementary PNP replacement for circuit symmetry. General-purpose NPN transistors like the 2N4403 may serve as functional substitutes in switching roles if pinout and package constraints allow.
