Review: Top Quality Parts! - Needed to fix a bad board in a Synology NAS. Found the part list and ordered these. Completed the job and tested. Everything works great!
Review: Fixed my Synology DS1515+ - Used this to fix my Synology DS1515+ that wouldn't power on. Replaced the transistor on Q2 on the MOBO. Worked like a charm. I ruined two transistors during the replacement. Still have 97 of them. Anyone wants one?

## Features

- Complementary to BC857
- Low collector-emitter saturation voltage
- Low noise between 30 Hz and 15 kHz
- For AF input stages and driver applications
- NOTE:Exposure to absolute maximum rating conditions for extended periods may affect device reliability
