Data for the 2SC3576, an NPN transistor per the JIS 2SC designation, supplied as a 108 KB PDF and filed among schematics. The 2SC series is defined for high-frequency bipolar NPN devices. During repair the document helps establish pin assignment, maximum collector voltage and current, power dissipation and gain, all of which matter when picking an equivalent or interpreting measurements. Nothing else is stated in the name. Check that the case and marking on the board correspond to the outline drawing before replacing the part.
