Datasheet for the 2N5195 bipolar transistor, a 120 KB PDF filed under schematics. The name gives no manufacturer or revision. It belongs to the 2N5191 to 2N5195 group of medium-power devices also present in this index. The sheet should list voltage and current limits, dissipation, gain curves and the package drawing including the tab connection. Use it when replacing driver or output transistors and when checking heatsink mounting. Compare polarity with the neighbouring part numbers before substituting.
