PC4SD11YXPCH

Triac, SCR Output Optoisolators Overview

The PC4SD11YXPCH is a single-channel phototriac optocoupler manufactured by Sharp Microelectronics. It features a non-zero-crossing triac output capable of blocking up to 800V in the off-state. The device provides 5000Vrms isolation voltage between input and output. It operates with a maximum forward current of 50mA and requires a trigger current of up to 5mA. The unit is housed in a 6-SMD surface-mount package and supports an operating temperature range from -30°C to +100°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix YXPCH against official Sharp datasheets to confirm the SMD package variant, as other suffixes may indicate different packaging or lead-free status. Confirm availability through authorized distributors, as component status can change. Ensure the supplier provides traceable documentation matching the manufacturer's part identification.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-angle control is required rather than zero-crossing switching. The 800V blocking voltage suits standard AC line applications. Verify that the 5mA trigger current aligns with the driving circuit capabilities. Ensure the design accommodates the thermal requirements within the specified -30°C to +100°C operating range.

Triac, SCR Output Optoisolators Part Context

This device belongs to the Sharp PC4SD series of Triac and SCR output optocouplers. It is designed for industrial and consumer AC power control applications requiring electrical isolation. The series offers various packaging options, with this specific model utilizing a surface-mount configuration for compact board designs.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct substitutes within the PC4SD family, such as PC4SD21NTZD, noting differences in zero-crossing functionality and trigger currents. Verify pinout compatibility and isolation ratings before substitution.
