APT1211WA

Overview

The Panasonic Electric Works APT1211WA is a single-channel optoisolator featuring a triac output. It provides 5000Vrms isolation voltage and supports a maximum off-state voltage of 600V. The device utilizes zero-crossing switching technology to minimize electromagnetic interference during AC load control. It is housed in a 4-DIP (gull-wing) package with through-hole mounting, designed for reliable operation across a temperature range of -40°C to 100°C.

Feature Summary

• Integrated zero-crossing circuitry for low-noise AC switching
• High isolation voltage rating of 5000Vrms
• Triac output configuration suitable for AC load control

Applications

• AC motor speed control circuits
• Solid-state relay modules
• Industrial process control systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix variant against official Panasonic Electric Works documentation to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status and packaging type directly with authorized distributors or the manufacturer before procurement. Cross-reference datasheet revisions to avoid discrepancies in mechanical dimensions or thermal ratings.

Selection Notes

Select this component when high-voltage isolation and noise reduction are critical for AC load applications. The zero-crossing feature makes it suitable for sensitive electronic environments where switching transients must be minimized. Ensure the load current requirements do not exceed the internal triac capabilities without external heat sinking or parallel configurations.
