Although often used as a direct replacement, it offers a higher voltage tolerance (up to 300V), making it superior for high-voltage switching, though with lower collector current than 2SC1124.
For purely high-voltage, low-current switching or video amplification: 250 V Current: 500 mA Package: TO-92 Do you have space constraints on your circuit board
A reliable, commonly available NPN transistor. While the voltage is lower ( 160V160 cap V ), it often works well in similar collector currents. B. "Better" Performance Replacements (Higher Voltage/Power) 2sc3953 sanyo transistor Go to product viewer dialog for this item.
The is an NPN silicon bipolar junction transistor (BJT) that has carved out a niche in high-quality audio amplification and switching applications. Renowned for its reliability in 1980s and 1990s Japanese consumer audio gear, this TO-220 packaged component is often sought after for amplifier repairs and vintage restorations.
