BC546A

Single Bipolar Transistors Overview

The BC546A is an NPN small signal transistor manufactured by Taiwan Semiconductor Corporation. It features a TO-92 package and supports a maximum collector current of 100 mA with a power dissipation rating of 500 mW. The device offers a collector-emitter voltage (VCEO) of 65 V and a collector-base voltage (VCBO) of 80 V. The DC current gain (hFE) for the 'A' group ranges from 110 to 220 at a collector current of 2 mA. It operates within a junction temperature range of -65°C to +150°C.

Single Bipolar Transistors Feature Summary

Low power loss and high efficiency design suitable for general-purpose switching applications.
High surge current capability allowing for robust performance under transient conditions.
RoHS compliant construction utilizing halogen-free molding compound that meets UL 94 V-0 flammability ratings.

Single Bipolar Transistors Applications

Switching mode power supply (SMPS)
On-board DC/DC converter
Lighting application

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix, such as A1 or B1, to confirm the packaging format, which varies between Ammo Box and Bulk quantities. Confirm RoHS compliance status and ensure the component meets JESD 201 class 1A whisker test requirements before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage NPN transistor with moderate current handling is required. The BC546A variant provides a lower current gain range compared to B or C groups, making it suitable for circuits where precise gain control is not critical. Ensure the operating voltage remains below the 65 V collector-emitter limit.

Single Bipolar Transistors Part Context

This part belongs to the BC546A/B/C series of NPN epitaxial silicon transistors produced by Taiwan Semiconductor. The series shares identical electrical ratings and mechanical dimensions, differing only in their DC current gain grouping. The BC546A specifically targets applications requiring the lowest gain tier within the standard BC546 family.
