STK433-100N-E

Overview

The STK433-100N-E is a four-channel Class-AB audio frequency power amplifier hybrid integrated circuit manufactured by Sanyo Semicon Device, now part of onsemi. This component delivers an output power of 80W per channel across four channels. It features pin-to-pin compatibility with other series models ranging from 40W to 80W, facilitating design flexibility. The device utilizes a miniature package and supports a recommended output load impedance of 6Ω. It includes provisions for standby and mute circuits compatible with pre-designed applications.

Feature Summary

• Four-channel Class-AB audio power amplification architecture
• Pin-to-pin compatibility within the STK433 series for design interchangeability
• Miniature package form factor for space-constrained applications
• Integrated support for standby and mute circuit configurations

Applications

• Audio power amplifiers
• Consumer electronics requiring multi-channel audio output
• Home theater systems

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally produced by Sanyo Semicon Device before corporate restructuring into onsemi. Confirm that the specific suffix matches the required power rating and channel configuration. Ensure the sourcing channel provides documentation linking the part to the original Sanyo datasheet specifications to guarantee technical accuracy and authenticity.

Selection Notes

Select this component when a four-channel audio solution is required with high power density. Consider the STK433 series hierarchy if different power outputs are needed, as the parts share pin compatibility. Evaluate the thermal requirements associated with the 80W per channel output at the specified load impedance. Verify that the system voltage rails align with the maximum ratings defined in the official electrical characteristics.

Part Context

This part belongs to the STK433 series of thick film hybrid ICs designed for audio applications. The series includes variants such as the STK433-040N-E and STK433-130N-E, offering scalable power options while maintaining mechanical and electrical interface consistency. The technology represents a mature class-AB amplification solution widely used in consumer audio equipment.

Replacement Considerations

Direct substitutes include other members of the STK433 series, such as the STK433-040N-E or STK433-130N-E, due to their pin-to-pin compatibility. Cross-reference with ON Semiconductor's current portfolio to ensure availability of equivalent performance levels.
