![]() ![]() ![]() Other nearest possible substitutes are A158C, BCY65X. BC107 will also work but the only difference is its maximum DC current gain is 450 but in most cases, it will not make a big difference. The exact match transistor for BC109 is BC108. The transistor is available in three different hFE values which are BC109 hFE value is 200 to 800, BC109B hFE value is 200-450 and BC109C hFE value is 420 to 800. Moreover, the maximum collector dissipation is 300mW and the DC current gain value is from 200 to 800, it also has a good noise figure of 4dB. The maximum collector to emitter voltage of the transistor is 20V which means that the transistor can drive maximum load voltage of 20V. The transistor is designed for general switching and amplification purposes, the maximum collector current is 100mA, however, you will also see some differences in the collector current of the transistor with different manufacturers, some manufacturers have this available in 50mA collector current and some have it available in 100mA, so it is better to first confirm the transistor’s collector current from the supplier you are buying from. It is the transistor of the BC10x series there are also other transistors in this series which are BC107 and BC108. It is a general-purpose transistor used in commercial and educational circuits.
