PC3SD11NXZC

Triac, SCR Output Optoisolators Overview

The PC3SD11NXZC is a single-channel Triac and SCR output optocoupler manufactured by Sharp Microelectronics. It features a PhotoTriac output device housed in a 6-SMD surface-mount package. The component provides an isolation voltage of 5000 Vrms between input and output circuits. Key electrical specifications include a maximum repetitive peak off-state voltage (VDRM) of 600 V, a maximum continuous output current of 100 mA, and a forward current (If) rating of 50 mA. The device operates without a zero-crossing circuit.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a PhotoTriac output for direct control of AC loads
• Provides high-voltage galvanic isolation via 5000 Vrms insulation
• Designed for surface-mount assembly using a compact 6-SMD footprint

Triac, SCR Output Optoisolators Applications

• Solid-state relay modules
• AC motor speed control circuits
• Lighting dimmer applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'NXZC' to confirm the surface-mount packaging variant, as other suffixes may indicate through-hole packages like PDIP-6. Confirm availability status with authorized distributors, as supply levels for this specific SMD variant may differ from standard DIP versions. Ensure the selected component matches the required thermal and mechanical constraints for the target PCB layout.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for AC switching applications. Compare the 600 V blocking voltage against the peak line voltage of the application. Verify that the 100 mA continuous current rating exceeds the load requirements. Consider the absence of zero-crossing detection if phase-angle firing is necessary for the specific load type.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp's Triac and SCR output optocoupler family. It shares functional similarities with through-hole variants such as the PC3SD11YTZCF but utilizes a different physical package. The series is designed for industrial and consumer electronics requiring reliable AC load switching with electrical isolation.
