(Right) Note: Always verify the specific manufacturer's pinout, as some variations may exist in older or specialized packages. 3. Common Applications
Before soldering a "better" replacement, . While the TO-220 package is standard, the pin assignments can vary by manufacturer. c1124 transistor datasheet better
Use the or "Translated" option. Look for the datasheet uploaded by Hitachi from 1983 – it has the clearest SOA graph. While the TO-220 package is standard, the pin
