APT1222

Overview

The Panasonic APT1222 is a phototriac coupler featuring a random phase triac output. It supports an AC load voltage of up to 600 V and handles a maximum continuous output current of 100 mA. The device provides 5000 Vrms isolation between input and output. It operates within a temperature range of -40°C to +100°C and utilizes a 6-DIP through-hole package.

Feature Summary

• Random phase switching capability for precise AC power control
• High voltage isolation ensuring circuit safety
• Robust triac output for moderate current loads

Applications

• Solid-state relay modules
• AC motor speed controllers
• Heating element regulation systems

Procurement Notes

Verify the specific suffix (e.g., WA, AX) to confirm package type and tape/reel configuration. Ensure the selected variant matches the required mounting style and packaging format for the target assembly process. Cross-reference official datasheets for exact mechanical dimensions and certification details before finalizing procurement.

Selection Notes

Select this component for applications requiring random-phase triggering without zero-crossing detection. It is suitable for general-purpose AC switching where immediate response is needed. Consider thermal management for the 100 mA output rating and ensure the control circuit can provide sufficient forward current.

Part Context

This part belongs to the APT series of phototriac couplers from Panasonic Electric Works. These devices are designed for industrial control applications requiring electrical isolation. The series offers various package options to suit different manufacturing needs while maintaining consistent electrical performance characteristics.

Replacement Considerations

Check Panasonic APT1222WA for DIP-6 variants or APT1222AX for surface-mount SMD versions with identical electrical specifications.
