Emerging as the industry's highest voltage bipolar transistors designed for audio amplifier output stages, the MJL4281A (NPN) and MJL4302A (PNP) 15A, 230W power transistors specify a sustained collector-to-emitter voltage of 350V. Comparable devices are said to be available with ratings up to 230V. Both transistors provide a safe operating area that allows for a collector current and voltage of 1.2A and 100V, respectively, at 1 second, which is said to enable high bandwidth and low-distortion output. Other features include a uniform linearity from 100 mA to 5A and gains from 80 to 250. Available in TO-264 packages, price is $1.85 each/10,000. ON SEMICONDUCTOR, PHOENIX, AZ. (800) 282-9855.
