Infineon Audio, 16-Pin, 500W DSO IRS20957STRPBF

This audio amplifier IC is a single-channel Class D device designed to drive high-power audio loads in consumer electronics. It operates from a 15V supply and is intended for integration into audio subsystems in televisions and domestic audio equipment. The component is supplied in a low-profile DSO package suitable for surface mounting and is specified to function across a wide temperature range for demanding operating environments.

• Class D topology delivers high-power output with efficient heat management
• 500W maximum output power enables strong audio performance for large loudspeakers
• Single-channel configuration simplifies mono amplification designs
• 16-pin DSO surface-mount package supports compact PCB layouts
• Operates from a 15V supply voltage for compatibility with common audio rails
• Rated for operation between -40 °C and 125 °C for broad thermal resilience

• Suitable for integration in television audio output stages
• Ideal for home sound systems requiring high-power mono amplification
• Used with powered speaker modules needing compact high-output drivers
• Can be used for single-channel public-address or subwoofer amplification

The device is a surface-mount DSO with 16 pins, so ensure the pad pattern and thermal copper pours match the package footprint to aid solderability and heat dissipation.

With a maximum operating temperature of 125 °C and minimum -40 °C, locate it away from persistent heat sources and provide appropriate PCB thermal management to maintain ambient temperature within the allowed range.

The amplifier requires a stable 15V supply capable of delivering the current demanded at up to 500W output

The part is not rated to automotive standards and should not be used where automotive certification is required.
