Audio transistors have highest voltage rating

25 February 2004 Analogue, Mixed Signal, LSI

A new family of audio bipolar transistors claimed to have the highest voltages available in the industry is being offered by ON Semiconductor. The MJL4281A (NPN) and MJL4302A (PNP) audio-output transistors provide the maximum amplification of an input signal currently available from a single transistor. These devices were designed with the high power demands required in high-end audio applications including professional audio amplifiers, theatre and stadium sound systems, and public address systems (PAs).

Both devices are 15 A, 230 W PowerBase power transistors that feature 350 V collector-emitter sustained voltage. Industry-standard devices available for these applications are only available up to 230 V. The devices deliver high bandwidth and high-gain linearity. The devices feature an excellent safe operating area (SOA) allowing 1,2 A collector current and 100 V at 1 second enabling high bandwidth and clean, low-distortion output. With uniform linearity from 100 mA to 5 A the devices deliver accurate reproduction of input signal. High gain (80 to 250) results in greater amplification of output signal.
