STK404-050C-E-ON

Overview

The STK404-050C-E-ON is a single-channel Class-AB audio power amplifier hybrid IC manufactured by onsemi. It utilizes insulated metal substrate technology (IMST) for miniaturization and features a low thermal resistance substrate to ensure compact packaging. The device integrates optimally designed discrete component power amplifier circuits into a single SIP package, providing high-power audio amplification capabilities suitable for demanding consumer electronics applications.

Feature Summary

• Integrates discrete power amplifier components within a single SIP package
• Utilizes Insulated Metal Substrate Technology (IMST) for structural integrity
• Features low thermal resistance substrate design for efficient heat dissipation

Applications

• Audio power amplifier systems
• Consumer electronics audio output stages
• High-fidelity sound reproduction equipment

Procurement Notes

Verify the specific suffix 'E' against official datasheets to confirm compliance with current material regulations. Ensure the supplier provides documentation confirming the part originates from onsemi's acquisition of SANYO semiconductor assets. Cross-reference the exact part number to distinguish between standard and automotive-grade variants if required by the application environment.

Selection Notes

Select this component when a monolithic solution for high-power audio amplification is required without the complexity of discrete circuit assembly. The integrated nature simplifies PCB layout and reduces component count. Consider the thermal management requirements associated with the SIP package size and the specific power output capabilities defined in the official electrical characteristics table.

Part Context

This component belongs to the STK404-000 series of audio power amplifier hybrid ICs. Originally developed by SANYO, these products are now supported under the onsemi portfolio following corporate restructuring. The series is characterized by its use of unique IMST technology, allowing for significant size reduction compared to earlier generations while maintaining robust performance standards for audio applications.

Replacement Considerations

Official substitutes include other members of the STK404-000 series, such as the STK404-140S-E or STK404-070N-E, depending on the required power output specifications. Verify pin compatibility and thermal characteristics before substituting, as power ratings vary across the series.
