BC550

Single Bipolar Transistors Overview

The onsemi BC550 is an NPN epitaxial silicon transistor designed for switching and amplifier applications. It features a collector-emitter voltage (VCEO) of 45 V, a collector-base voltage (VCBO) of 50 V, and an emitter-base voltage (VEBO) of 5 V. The device supports a maximum DC collector current of 100 mA with a power dissipation rating of 500 mW. Key electrical characteristics include a DC current gain (hFE) ranging from 110 to 800, a transition frequency (fT) of 300 MHz, and a low noise figure between 1.2 dB and 4.0 dB.

Single Bipolar Transistors Feature Summary

Low-noise performance suitable for sensitive signal processing circuits
Complementary pairing with the BC560 PNP transistor series
High-voltage capability within the standard TO-92 package

Single Bipolar Transistors Applications

General-purpose amplification stages
Electronic switching circuits
Audio pre-amplifier designs requiring low noise

Single Bipolar Transistors Procurement Notes

Verify the specific hFE bin (A, B, or C) required for your circuit design, as gain ranges vary significantly across these classifications. Confirm that the TO-92 bulk or ammo packing method aligns with your assembly process. Ensure compliance with RoHS standards if applicable to your manufacturing requirements.

Single Bipolar Transistors Selection Notes

Select the BC550 when low noise figures are critical compared to the standard BC548 or BC547 variants. Consider the hFE classification based on the required current gain consistency for your amplifier biasing. Verify that the 45 V collector-emitter voltage rating meets the maximum operating voltage of your application.

Single Bipolar Transistors Part Context

The BC550 belongs to the BC546 through BC550 family of NPN epitaxial silicon transistors manufactured by onsemi. This series provides various voltage ratings and gain classifications to suit different electronic design needs. The BC550 specifically addresses applications requiring low noise characteristics while maintaining standard small-signal transistor form factors.
