Sheet for the TIP31 NPN and TIP32 PNP complementary power transistor pair, with the name stating 100 V and 3 A ratings; the PDF is 198 KB and listed under schematics. Expect characteristic curves, gain figures, dissipation and TO-220 pin layout. In repair work it helps verify transistors in amplifier and driver stages, understand which letter suffix gives the needed voltage grade, and confirm the tab is the collector. Any PDF reader opens the file; match the exact suffix and polarity on the fitted part before replacing it.
