PC3SD11NXZB

Triac, SCR Output Optoisolators Overview

The PC3SD11NXZB is a single-channel phototriac optocoupler manufactured by Sharp Microelectronics. It features a 6-SMD surface-mount package and provides electrical isolation with a rated insulation voltage of 5000 Vrms. The device includes a photo-triac output without an integrated zero-crossing circuit, designed for non-zero-crossing applications. Key electrical specifications include a maximum repetitive peak off-state voltage (VDRM) of 800 V and a maximum continuous output current of 100 mA. The input side supports a forward current (If) up to 50 mA with a typical forward voltage of 1.2 V. The component operates within a temperature range of -30°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between input control circuits and output loads via optical coupling.
• Features a non-zero-crossing triac output suitable for phase-angle control applications requiring immediate response.
• Utilizes a compact 6-SMD surface-mount package design for automated assembly integration.

Triac, SCR Output Optoisolators Applications

• Solid-state relays requiring fast switching response
• AC motor speed control circuits
• Lighting dimmer systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'NXZB' against official Sharp Microelectronics documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the non-zero-crossing characteristic aligns with the target application's noise immunity requirements, as this variant lacks the soft-switching benefits of zero-crossing models. Cross-reference the 6-SMD footprint dimensions with PCB layout guidelines to prevent soldering defects during reflow processes.

Triac, SCR Output Optoisolators Selection Notes

Select this component when immediate turn-on capability is required rather than zero-crossing synchronization. The 800 V blocking voltage rating suits standard AC line voltages. Verify that the 100 mA output current capacity meets the load requirements. Consider the 6-SMD package constraints if space is limited compared to through-hole alternatives like the PC4SD series. Confirm thermal management needs given the operating temperature range limits.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp Microelectronics' family of Triac and SCR output optocouplers. It serves as a surface-mount alternative to through-hole variants such as the PC4SD11NTZCF or PC3SF11YVZAF. While sharing similar electrical isolation and output characteristics, the PC3SD11NXZB distinguishes itself through its SMD form factor, facilitating different PCB mounting strategies and automation processes in modern electronic manufacturing.

Triac, SCR Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may include other Sharp non-zero-crossing triac optocouplers in 6-SMD packages. Verify equivalent VDRM and I_T(RMS) ratings before substitution. Cross-model comparisons should account for differences in dV/dt ratings and trigger current specifications to ensure functional equivalence in the specific circuit topology.
