Here is an image showing the pin diagram of this transistor.The 2SA1292-S transistor can have a current gain of 140 to 280. The gain of the 2SA1292 will be in the range from 70 to 280, for the 2SA1292-Q it will be in the range from 70 to 140, for the 2SA1292-R it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SA1292-S might only be marked "A1292-S".The complementary NPN transistor to the 2SA1292-S is the 2SC3256-S.You can replace the 2SA1292-S with the BD246A, BD246B, BD246C, BD250A, BD250B, BD250C or TIP36CA.
