STK433-060-E

Overview

The STK433-060-E is a four-channel Class-AB audio frequency power amplifier hybrid IC manufactured by Sanyo. It delivers an output power of 50W per channel into a 6Ω load, totaling 200W across all channels. The device supports an allowable load shorted time of 0.3 seconds and recommends a load impedance of 6Ω. It features pin-to-pin compatibility with other models in the series, allowing for flexible design integration.

Feature Summary

• Four-channel Class-AB audio power amplification architecture
• Pin-to-pin compatible with outputs ranging from 40W to 80W
• Miniature package design for space-constrained applications
• Supports pre-designed standby and mute circuit configurations

Applications

• Audio power amplifiers
• Multi-channel speaker systems
• Home theater receiver designs

Procurement Notes

Verify the manufacturer origin as Sanyo Semicon Device or its successor entities. Confirm the specific suffix matches the required pinout and thermal characteristics. Ensure documentation aligns with the official datasheet specifications for voltage ratings and output power metrics before integration.

Selection Notes

Select this component when a four-channel configuration is required for high-power audio applications. It serves as a direct replacement for legacy two-channel designs due to its pin-compatible nature with the broader STK433 series, facilitating easier upgrades without significant PCB redesign.

Part Context

This part belongs to the STK433 series of thick film hybrid ICs designed for audio power amplification. The series offers various power levels, with this model providing 50W per channel. It is engineered for consumer electronics requiring robust performance in a compact form factor.

Replacement Considerations

Pin-to-pin compatible alternatives within the same series include the STK433-040N-E (40W x 4ch) and STK433-130N-E (150W x 2ch). Verify voltage ratings and thermal management requirements when substituting with higher or lower power variants.
