Overview
The APT1221WAY is a single-channel Triac output optocoupler manufactured by Panasonic Electric Works. It features a PhotoTriac output capable of handling a maximum continuous output current of 100 mA and blocking voltages up to 600 V. The device provides an isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. It operates without a zero-crossing circuit, classifying it as a random phase device suitable for AC power control applications. The component is housed in a 4-DIP gull-wing package designed for through-hole mounting.
Feature Summary
- Random phase operation allows triggering at any point in the AC waveform cycle
- High insulation capability with 5000 Vrms isolation rating
- Integrated PhotoTriac output for direct AC load switching
- Designed for reliable performance across extended temperature ranges
Applications
- AC motor speed control systems
- Solid state relay (SSR) modules
- Industrial process control interfaces
- Consumer appliance power regulation
Procurement Notes
Verify the specific suffix 'WAY' against the manufacturer's latest datasheet to confirm package style and reel specifications. Ensure compatibility with existing PCB footprints for 4-DIP gull-wing configurations. Cross-reference RoHS compliance status and safety certifications such as cUR and VDE before finalizing procurement decisions.
Selection Notes
Select this component when random phase triac control is required rather than zero-crossing switching. Confirm that the 100 mA output current rating meets the load requirements. Verify that the 600 V blocking voltage is sufficient for the target AC line voltage. Ensure the through-hole DIP-4 package fits the assembly constraints.
Part Context
This part belongs to the APT series of phototriac couplers from Panasonic Electric Works. The series offers various packaging options including tubes and reels. The APT1221WAY specifically denotes the reel-packaged variant with gull-wing leads, distinguishing it from tube-packed versions like the APT1221A.
Replacement Considerations
The APT1221AX is listed as a substitute part number within the same product family. Verify pinout compatibility and electrical parameter equivalence before substitution.
