151-0232-00

The SP12141  (P/N 151-0232-00) is a dual NPN transistor in a 6-pin TO-78 package. It is widely used in Tektronix instruments of the 1960, 1970s, and 1980s.

According to the RPR, the 151-0232-00 is a Fairchild SP12141, the 151-0232-02 is an SP14319. The 151-0232-03 is a 2N2918.

Other evidence suggests that it is a 2N2915, which is also a dual NPN silicon transistor.
