Therefore it can be used in up to 70W high power audio amplifier output stage. These characteristics also make this transistor suitable to use in switching applications to drive load of up to 10A.Īs said above this transistor is designed for audio amplification purposes but can also be used in switching circuits. The max collector to emitter voltage of the transistor is 140V and the max collector current is 10A and 1A base current will be required to get 10A output current with the typical collector-emitter saturation voltage of 0.3V. It is mostly used with its PNP complimentary transistor 2SA1941 to build audio amplifier circuits. It performs very well in amplifier circuits and provides the same sound quality as the input at the output with added amplification therefore ideal to use in the output stages of high power audio amplifiers. This transistor is mainly built for audio amplification purposes and performs very well over the full range of audio frequencies from 20Hz to 20 kHz. Minimum & Maximum DC Current Gain (h FE): 55 To 160.Max Collector Dissipation (Pc): 100 Watt.Max Collector-Base Voltage (V CB): 140V.Max Collector-Emitter Voltage (V CE): 140V.
