STK433-060N-E

Overview

The STK433-060N-E is a four-channel Class-AB audio frequency power amplifier hybrid IC manufactured by Sanyo Semicon Device, now part of onsemi. It delivers 50W per channel into a 6Ω load. The device features a miniature package and supports pin-to-pin compatibility with other series models ranging from 40W to 80W output power. Recommended operating supply voltage is ±27V for a 6Ω load, with maximum ratings up to ±46V quiescent.

Feature Summary

• Four-channel Class-AB audio power amplification
• Pin-to-pin compatible with 40W to 80W series variants
• Miniature package design
• Supports standby and mute circuit integration

Applications

• Audio power amplifiers
• Home theater systems
• Professional audio equipment

Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Sanyo Semicon Device before acquisition by onsemi. Confirm the specific datasheet version and ordering number (ENA2109) to ensure alignment with the intended electrical characteristics and mechanical dimensions. Check for any RoHS compliance markings or environmental declarations associated with the specific production batch.

Selection Notes

Select this model when a four-channel configuration is required with 50W per channel output capability. Ensure the load impedance is approximately 6Ω for optimal performance within the recommended operating voltage range of ±27V. Consider pin-to-pin alternatives like the STK433-040N-E or STK433-130N-E if different power levels are needed without changing the PCB layout.

Part Context

This component belongs to the STK433 series of audio power amplifier hybrid ICs. The series offers various power outputs, including 40W, 60W, and 130W configurations, allowing designers to scale power requirements while maintaining mechanical and electrical interface consistency across different product lines.

Replacement Considerations

The STK433-040N-E and STK433-130N-E are officially documented pin-to-pin compatible series models. Verify that the application can accommodate the lower or higher power ratings respectively without requiring changes to the heat sinking or power supply design.
