Description
By adapting the Sanken unique wafer-thinner technique, these
PNP power transistors achieve power-up by decreasing thermal
resistance, and provide higher voltage avalanche breakdown
rating. The high power-handling capacity of the TO-3P package
allows a smaller footprint on the circuit board design. This
series of transistors is very well suited to not only multichannel
applications for AV (audio-visual) amplifiers and receivers,
but also parallel connection applications for PA (professional
audio system) amplifiers.
Applications include the following:
▪ Single transistors for audio amplifiers
▪ Home audio amplifiers
▪ Professional audio amplifiers
▪ Automobile audio amplifiers
▪ Audio market
▪ Single transistors for general purpose
