APT1232WAY

Overview

The Panasonic APT1232WAY is a single-channel phototriac output optocoupler housed in a 6-DIP Gull Wing package. It features an integrated zero-crossing circuit for low electromagnetic interference switching. Key electrical parameters include a maximum continuous output current of 100 mA, a peak off-state voltage (VDRM) of 600 V, and an isolation voltage of 5000 Vrms. The device operates with a forward current up to 50 mA and has a maximum trigger current of 10 mA. It supports a wide operating temperature range from -40°C to +100°C.

Feature Summary

• Integrated zero-crossing detection circuitry minimizes electromagnetic interference during AC load switching.
• High insulation capability ensures safe galvanic isolation between input control circuits and high-voltage outputs.
• Robust triac output stage designed for reliable commutation in resistive and inductive AC loads.

Applications

• Solid state relays for AC power control
• Motor speed controllers
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix 'WA' against official Panasonic documentation to confirm pinout and packaging details, as distributor listings may vary. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check for Not Recommended for New Design (NRND) status if applicable to long-term supply chain planning.

Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC applications. Ensure the load voltage does not exceed the 600 V rating and the current remains within the 100 mA limit. Verify that the DIP-6 Gull Wing package fits the target PCB footprint and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the Panasonic APT series of optocouplers, which are engineered for industrial automation and consumer appliance control. The series emphasizes reliability and safety certifications, making it suitable for applications requiring strict isolation standards and robust performance under varying thermal conditions.

Replacement Considerations

Consult official Panasonic substitution guides for direct equivalents. Generic replacements must match the 6-pin DIP Gull Wing package, 5000 Vrms isolation, and zero-crossing functionality. Verify pin compatibility and electrical ratings before integration.

FAQ

Does the APT1232WAY include internal zero-crossing detection?

Yes, the device integrates a zero-crossing circuit to ensure the triac turns on only when the AC voltage is near zero, reducing electrical noise.

What is the maximum isolation voltage of this optocoupler?

The APT1232WAY provides an isolation voltage of 5000 Vrms between the input LED and the output triac.
