APT1222AX

Overview

The Panasonic Electric Works APT1222AX is a single-channel triac output optoisolator designed for random phase triggering applications. It features a 5000Vrms isolation voltage and supports an on-state RMS current of 100mA with a peak repetitive off-state voltage of 600V. The device operates within a temperature range of -40°C to +100°C and utilizes a 6-DIP gull wing package. Key electrical parameters include a maximum turn-on time of 100µs, a minimum static dV/dt of 500V/µs, and a typical forward voltage of 1.21V.

Feature Summary

• Random phase triggering capability for precise AC power control
• High isolation voltage of 5000Vrms for safety compliance
• Robust noise immunity with a minimum static dV/dt rating of 500V/µs

Applications

• Solid State Relay (SSR) input stages
• AC motor speed control circuits
• Lighting dimmer modules

Procurement Notes

Verify the specific ordering suffix against the official Panasonic datasheet to ensure the correct package variant and certification marks are selected. Confirm that the component meets required safety standards such as VDE or UL for the target application region. Cross-reference the date code and manufacturing origin to ensure supply chain consistency and compliance with RoHS directives.

Selection Notes

Select this component when random phase firing is required rather than zero-cross switching. Ensure the circuit design accommodates the 100mA on-state current limit and the 600V blocking voltage. Verify that the 10mA maximum trigger current aligns with the driving LED source capabilities and that the operating temperature range suits the environmental conditions.

Part Context

This part belongs to the APT series of phototriac couplers from Panasonic Electric Works. It serves as a critical interface between low-voltage control logic and high-voltage AC loads. The series is widely used in industrial automation and consumer electronics where reliable galvanic isolation and rapid switching response are necessary for safe operation.

Replacement Considerations

Consult the official Panasonic replacement guide for direct equivalents. Generic substitutes may differ in isolation voltage ratings or trigger current specifications. Verify pin compatibility and thermal characteristics before integrating alternative components into existing designs.
