| Good low-noise audio NPN transistors for headphone amplifier |
| (1/1) |
| TheUnnamedNewbie:
I'm designing a (silly) headphone amp as a project. I would like some output NPN transistors for the final stage. I get about 1W of dissipation in the device and 500 mA max collector current. Preferably available in through-hole since this project will be bread-boarded and all that. Don't need a device that has a complementary PNP. |

Low noise isn't important for the output stage, since it's a unity gain emitter follower. How about the BD135? https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=17&ved=2ahUKEwju1-j0hLLlAhVStHEKHRDWAvoQFjAQegQIBxAH&url=https%3A%2F%2Fwww.st.com%2Fresource%2Fen%2Fdatasheet%2Fcd00001225.pdf&usg=AOvVaw1y7-G52L03pc8C9L8-XXTo |
