Here is an image showing the pin diagram of this transistor.The 2SB697K transistor can have a current gain of 40 to 320. The gain of the 2SB697K-C will be in the range from 40 to 80, for the 2SB697K-D it will be in the range from 60 to 120, for the 2SB697K-E it will be in the range from 100 to 200, for the 2SB697K-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SB697K might only be marked "B697K".The complementary NPN transistor to the 2SB697K is the 2SD733K.You can replace the 2SB697K with the 2SA909.
