PNP transistor for symmetric push-pull configurations in Class AB audio output stages. High Voltage Handling: cap V sub cap C cap E cap O end-sub c1124 transistor datasheet better
instead of 120V+), leading to distortion or burnout under load. Modern Substitutes:
Several highly reliable industry-standard transistors surpass the original specifications of the C1124:
): Usually rated around 100-200mA (depending on manufacturer variant) Often in the 1-2W range (depending on package/heatsink) Transition Frequency ( fTf sub cap T ): Good for high-frequency video circuits. The key strength of the 2SC1124 is its 160V VCEOcap V sub cap C cap E cap O end-sub , making it excellent for high-voltage driving tasks. 2. When Do You Need a "Better" Transistor? ), it was often utilized in broadcast equipment
0.9 W (Can be significantly improved with a small heatsink) Transition Frequency ( fTf sub cap T ): 50 MHz
Original metal-can 2SC1124 transistors are out of production. New old stock (NOS) parts are increasingly rare and prone to counterfeiting.
Used in the driver or output stages of hi-fi systems due to its high voltage handling and linear gain. This link or copies made by others cannot be deleted
: Widely used in the pre-driver and driver stages of hi-fi audio amplifiers. Complementary Pair : It is frequently paired with the
power limit to prevent thermal runaway or failure at the maximum junction temperature.
