STK404-070N-E

Overview

The STK404-070N-E is a single-channel Class-AB audio power amplifier hybrid IC manufactured by ON Semiconductor. It delivers 60W of output power and utilizes insulated metal substrate technology (IMST) for miniaturization. The device integrates optimally designed discrete component circuits on a low thermal resistance substrate, providing a compact solution compared to earlier similar specifications.

Feature Summary

• Single-channel Class-AB audio power amplifier configuration
• Insulated metal substrate technology (IMST) for miniaturization
• Low thermal resistance substrate design

Applications

• Audio power amplifier systems
• Hybrid integrated circuit designs

Procurement Notes

Verify the manufacturer designation as ON Semiconductor or Sanyo Semicon Device when sourcing. Confirm the specific suffix N-E matches the required single-channel 60W Class-AB specification. Ensure compatibility with existing hybrid package footprints during replacement planning.

Selection Notes

Select this component for applications requiring a single-channel Class-AB audio amplifier with high power density. The IMST technology supports compact form factors where space is limited. Evaluate thermal management requirements based on the low thermal resistance substrate characteristics for reliable operation.
