Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD525 is the BD526.The 2SC3444 (SOT-89), 2SC3444-C (SOT-89), 2SC3444-D (SOT-89), 2SC3444-E (SOT-89), 2STR1160 (SOT-23), BCP55 (SOT-223), BCP55-10 (SOT-223), BCP55-16 (SOT-223), BCX55 (SOT-89), BCX55-10 (SOT-89), BCX55-16 (SOT-89), BSP41 (SOT-223), BSR40 (SOT-89), BSR41 (SOT-89) and FZT692B (SOT-223) is the SMD version of the BD525 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD525 with the BD517, BD519, BD527, BD529 or NTE188.
