ON Semiconductor Introduces Industry’s Highest Voltage Audio Bipolar Transistors for Audio Amplifier Output

Share

New transistor and corresponding drivers providing the maximum amplification from a single transistor for high-end audio market applications

Phoenix, Ariz. – Oct. 22, 2003 – ON Semiconductor (Nasdaq: ONNN), a leading global supplier of standard components, today introduced a new family of audio bipolar transistors with the highest voltages available in the industry. 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, theater and stadium sound systems, and public address systems (PAs).

Features and Benefits
The MJL4281A (NPN) and MJL4302A (PNP) are 15 amp, 230 watt PowerBase™ power transistors that feature 350 volt (V) collector-emitter sustained voltage. Competitive 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 amps collector current and 100 V at 1 second enabling high bandwidth and clean, low-distortion output. With uniform linearity from 100 milliamps to 5 amps the devices deliver accurate reproduction of input signal. High gain (80 to 250) results in greater amplification of output signal.

Packaging and Price
The MJL4281A and MJL4302A amplifiers are offered in the TO-264 package and priced at $1.85 per unit in 10,000 unit quantities. Drivers to complement these high voltage output transistors also have been released. The MJE15034 and MJE15035 are available in TO-220 packages priced at $0.36 per unit in 10,000 unit quantities.
