PC3SD11YXPCH

Triac, SCR Output Optoisolators Overview

The PC3SD11YXPCH is a single-channel phototriac output optocoupler manufactured by Sharp Microelectronics. It features a gallium arsenide infrared LED coupled to a triac detector, providing electrical isolation with a rated insulation voltage of 5000 Vrms. The device utilizes a surface-mount 6-SMD (5 Leads) gull-wing package designed for through-hole reflow soldering processes. Key electrical characteristics include a maximum forward current of 50 mA and a peak repetitive off-state voltage capability of 800 V. The unit operates within a temperature range of -30°C to +100°C and lacks an integrated zero-crossing circuit.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between control circuits and AC loads via optical coupling
• Integrates a sensitive gate triac detector suitable for direct driving of small AC loads
• Utilizes a compact surface-mount package compatible with standard SMT assembly lines

Triac, SCR Output Optoisolators Applications

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

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity upon receipt as the PC3SD11YXPCH has been identified as discontinued in major distributor catalogs. Confirm that the received units match the original manufacturing specifications and package markings. Ensure storage conditions comply with moisture sensitivity levels prior to soldering. Validate supplier documentation against official Sharp Microelectronics records to mitigate risks associated with obsolete or refurbished inventory sources.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for isolating low-power AC control signals from high-voltage mains. The absence of a zero-crossing feature makes it appropriate for phase-angle firing applications rather than soft-switching requirements. Compare the 800 V blocking voltage against load requirements and ensure the 100 mA continuous output current rating exceeds the connected load's holding current needs.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp Microelectronics' PC series of optoisolators, which are widely used for general-purpose isolation. The PC3SD11YXPCH specifically adapts the traditional DIP-6 form factor into a surface-mount footprint to facilitate automated assembly. It serves as a bridge between microcontroller logic levels and AC power stages, offering robust performance in compact electronic designs requiring galvanic separation.
