This document is a technical datasheet for the Siemens AC 151, an alloyed germanium PNP transistor designed for AF input and driver stages. The device features a 1A DIN 41871 case with electrically insulated leads and requires a separate heat sink for mounting.
The datasheet provides comprehensive electrical specifications including maximum ratings such as collector-emitter voltage (20.2 V) and total power dissipation (900 mW). It also details static characteristics like cutoff frequency (15 kHz) and transition frequency (1.6 MHz), along with dynamic performance graphs for current gain, output characteristics, and noise figure.
| Total power dissipation | 900 mW |
|---|---|
| Cutoff frequency (fT) | 15 kHz |
| Transition frequency (fr) | 1.6 MHz |
| Base intrinsic resistance | 75 Ohms |
The approximate weight of the AC 151 transistor is 1g.
The maximum total power dissipation is 900 mw.
Yes, the fixing part (heat sink) has to be ordered separately.
