MOSFET Drives Class D Audio Amps

Supporting medium-power Class D audio amplifiers, the IRF6665 DirectFET MOSFET employs application-tuned parameters for improving audio performance, such as efficiency, total harmonic distortion, and power density. The device allows for 100W operation into an 8W load without a heatsink. Features include a typical on resistance of 51 mW at 10V, BVDSS of 100V, and an ID of 19A at TC=25°C. Price is $0.52 each/10,000. For more information, contact Wayne Yoshida at INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7726.
