AD 149, AD 150
PNP Transistors for AF power stages up to 20 W
AD 149 and AD 150 are germanium PNP alloyed transistors in a TO-3 package.
The collector is electrically connected to the case. For insulated mounting of these
transistors on a chassis, the insulating parts Q 62901-B 11-A and Q 62901-B 13-B
are provided. These parts have to be ordered separately.
AD 149 and 150 are recommended for use in high-quality AF power stages.
For use in push-pull power stages, these transistors are also available in pairs.

Static characteristics (TMtt = 25 °C)
The transistors AD 149, AD 150 are classified in groups of static forward current
transfer ratio B (- 7C ™ 1 A), which are indicated by Roman numerals. The following
values apply at a collector-emitter voltage l/CE = 1 V and the following collector

1) Tho transistor is overdriven to such an exert that the static forward curent transfer ratio has decrea-
sed to B = 10 (-/c = 3A: B = 10)
2) (/c ~ 3A applies for the characteristicscurve which, at constant base current, passes the point
/c = 3.3 A. VCf = 1V).
