International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
Applications for Class D amplifiers range from battery-powered portable products to high-end professional amplifiers, musical instruments and car and home multimedia systems.
In addition to application-tuned silicon, IR's DirectFET packaging technology enhances performance in Class D audio amplifier circuits by reducing lead inductance, which improves switching performance and reduces EMI noise.
Thermal efficiency enables 100W operation into 8ohm without a heatsink.
Eliminating heatsinks shrinks circuit size and bulk, giving designers more layout flexibility and reduces amplifier cost.
Critical MOSFET parameters determining Class D audio performance include device on-resistance and gate charge.
These parameters can determine efficiency in a Class D audio amplifier.
The new IRF6665 Class D audio DirectFET MOSFET is available immediately.
Pricing is US $0.52 each in 10,000-unit quantities.
