H-1535A1
RCAlC09 is an n·p·n hometaxial·base silicon power transistor packaged in the JEDEC TO·220AB (VERSAWATT) case. Two of these devices. driven in the class·B mode by the RCA1A06 and RCA 1A05 silicon n·p·n and p·n·p transistors, can be used as output devices in audio·amplifier applications.
The 4lJ.watt amplifier shown in Figs. 1 and 5 uses two RCA 1C09 transistors as output units in conjunction with seven TO·39 transistors, 11 diodes, and a 64·volt split power supply. The amplifier output is directly coupled to an B-ohm speaker.
