Power Transistors RCA1C14
Silicon Transistor for 25-WaH Quasi-Complementary-Symmetry Audio Amplifiers
JEDEC TO·220AB
H-1535R1
RCA1C14 is an n·p·n hometaxial·base silicon power transistor provided in the JEDEC TO·220AB package. This device is ideally suited for use in the output stage of quasi· complementary-symmetry audio amplifiers
The 2&watt audio·amplifier circuit shown in Figs. 1 and 5
uses two .RCA1C14 transistors in conjunction with seven TO·39 low·level audio transistors, 11 diodes, and a 52·volt split supply. The amplifier output is directly coupled to an Iklhm speaker. Ruggedness and economy are features of this high fidelity amplifier.
