APT1212

Overview

The Panasonic Electric Works APT1212 is a phototriac coupler featuring an integrated zero-crossing circuit. It provides electrical isolation with a rated voltage of 5000Vrms and supports a peak off-state voltage of 600V. The device handles a maximum RMS on-state current of 100mA and operates within a temperature range of -40°C to 100°C. Key electrical parameters include a maximum forward current of 50mA, a typical forward voltage of 1.21V, and a minimum static dv/dt rating of 500V/µs. The component utilizes a 6-DIP package for through-hole mounting.

Feature Summary

• Integrated zero-crossing detection circuitry for reduced electromagnetic interference during switching
• High isolation voltage capability of 5000Vrms between input and output sections
• Robust noise immunity characterized by a high static dv/dt rating of 500V/µs

Applications

• Solid-state relay driver circuits requiring phase control
• AC power switching applications in industrial automation systems
• Motor control interfaces for AC motors

Procurement Notes

Verify the specific package variant when ordering, as the base model number may correspond to different physical footprints such as DIP or surface mount configurations depending on the suffix. Confirm RoHS compliance status and check for active production lifecycle notices. Ensure the selected variant matches the required mounting style for the target PCB design.

Selection Notes

Select this component for applications necessitating precise timing synchronization with AC line cycles due to the built-in zero-crossing feature. Evaluate the thermal management requirements given the operating temperature range up to 100°C. Consider the 600V blocking capability relative to the load voltage levels to ensure adequate safety margins against transient spikes.

Part Context

This device belongs to the APT series of phototriac couplers manufactured by Panasonic Electric Works. The series is designed for reliable isolation in AC power control environments. The APT1212 specifically integrates zero-crossing logic, distinguishing it from standard triac outputs that switch immediately upon LED activation.
