Hello every one NOW I'm quite confused I know I also have a thread running on the High Bridge controller. This Item is a component on that board but I have found two conflicting pinout sheets and I'm now quite lost.
OK on the Schematics (attached below)
1 Emitter
2 Collector
3 Base
which is fine Now one of the members here suggested that they where the wrong way around. on the schematic so that got me looking ? but on the following ST Microelectronics
This Link http://docs-europe.electrocomponents.com/webdocs/002d/0900766b8002db67.pdf
the information contradicts the schematics in saying that
1 Base
2 Collector
3 Emitter
But this data sheet Link http://www.datasheetdir.com/ISCSEMI-BD139+Power-Transistors
This information confirms the schematic
1 Emitter
2 collector
3 Base
what is the correct pin configuration with the white writing facing front so there for the heat sink part is facing to the rear of the part.
Am I just having a blond moment
