APT1212AX

Overview

The Panasonic APT1212AX is a Triac and SCR output optocoupler designed for high-voltage AC applications up to 600V. It features a DIP-6 package with gull-wing leads, providing 5000Vrms isolation voltage. The device supports a maximum continuous output current of 100mA and includes a zero-crossing circuit triggered at 50V. Key electrical parameters include a forward current of 50mA, forward voltage of 1.21V, power dissipation of 500mW, and a maximum turn-on time of 100µs. Operating temperature ranges from -40°C to +100°C.

Feature Summary

• Integrated zero-crossing detection circuitry for reduced electromagnetic interference during switching
• High insulation voltage capability of 5000Vrms for robust electrical isolation
• DIP-6 surface mount compatible package design for automated assembly

Applications

• Industrial automation control systems requiring AC load switching
• Solid-state relay (SSR) driver circuits
• AC motor control interfaces
• Power supply feedback isolation loops

Procurement Notes

Verify the specific suffix designation when ordering, as Panasonic utilizes distinct suffixes such as WA and AX to denote variations in packaging or manufacturing lot specifications. Confirm that the required isolation voltage and current ratings align with the target application's safety standards before procurement. Ensure compatibility with the intended PCB footprint for the DIP-6 configuration.

Selection Notes

Select this component when high-voltage isolation exceeding 2500Vrms is required alongside precise zero-crossing switching capabilities. Compare against standard triac outputs if lower isolation voltages suffice, as this part prioritizes safety margins. Consider the 100mA output limit for load sizing and verify thermal management requirements given the 500mW power dissipation rating in enclosed environments.

Part Context

This device belongs to the APT series of phototriac couplers manufactured by Panasonic Electric Works. It serves as a critical interface component between low-voltage control logic and high-voltage AC power stages. The series is engineered for reliability in industrial environments, offering consistent performance across the specified temperature range while maintaining strict galvanic isolation standards.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter equivalence with alternative manufacturers' triac output optocouplers before substitution.
