Here is an image showing the pin diagram of this transistor.The BD378 transistor can have a current gain of 40 to 375. The gain of the BD378-10 will be in the range from 63 to 160, for the BD378-16 it will be in the range from 100 to 250, for the BD378-25 it will be in the range from 150 to 375, for the BD378-6 it will be in the range from 40 to 100.The complementary NPN transistor to the BD378 is the BD377.You can replace the BD378 with the BD190, BD236, BD236G, BD238, BD238G, BD380, MJE235, MJE252 or MJE254.
