BC548CTA

Single Bipolar Transistors Overview

The BC548CTA is an NPN silicon epitaxial planar transistor manufactured by Fairchild Semiconductor. It features a collector-emitter breakdown voltage of 30 V and a continuous collector current rating of 100 mA. The device provides a minimum DC current gain (hFE) of 200, ensuring high amplification capability for small signal applications. It is housed in a lead-free TO-92 package with three pins, designed for through-hole mounting. The component operates within a junction temperature range up to 150 °C and complies with RoHS standards.

Single Bipolar Transistors Feature Summary

• High DC current gain suitable for sensitive amplification tasks
• Lead-free construction compliant with environmental directives
• Epitaxial planar design for stable switching performance

Single Bipolar Transistors Applications

• General purpose amplifier circuits
• Switching applications requiring low power control
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'CTA' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the order matches the required hFE binning grade 'C' for consistent gain characteristics. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by Fairchild or its successor entity.

Single Bipolar Transistors Selection Notes

Select this component when a minimum hFE of 200 is required for the BC548 series. Compare against BC548BTA for lower gain requirements or BC548ATA for standard gain levels. Confirm that the 30 V collector-emitter voltage rating aligns with the circuit's maximum operating conditions. Verify package compatibility with existing PCB footprints.

Single Bipolar Transistors Part Context

The BC548CTA belongs to the BC546/547/548 family of NPN general-purpose transistors. This series offers complementary PNP devices such as the BC556, BC557, and BC558. The 'C' suffix denotes a specific current gain binning, while 'TA' typically indicates tape and reel packaging. These transistors are widely used in consumer electronics and industrial control systems.

Single Bipolar Transistors Replacement Considerations

Equivalent parts include BC548C from other manufacturers like Diotec or Vishay. Verify pinout alignment and thermal resistance values before substitution.
