The 2SC1124 is a vintage, high-voltage NPN silicon BJT designed for audio amplification, featuring 140V-160V VCEOcap V sub cap C cap E cap O end-sub
Before soldering a "better" replacement, . While the TO-220 package is standard, the pin assignments can vary by manufacturer. c1124 transistor datasheet better
The C1124 had poor thermal transfer. A "better" transistor will have a lower RθJA, meaning it stays cooler for the same power dissipation. The 2SC1124 is a vintage, high-voltage NPN silicon
