PC3SD21YXPLF

Triac, SCR Output Optoisolators Overview

The PC3SD21YXPLF is a single-channel phototriac output optocoupler manufactured by Sharp Microelectronics. It features an integrated zero-crossing detection circuit for low electromagnetic interference switching. The device provides 5000 Vrms insulation voltage between input and output. It supports a maximum repetitive peak off-state voltage (VDRM) of 600 V and an RMS on-state current (ItRMS) of 100 mA. The input side operates with a forward current (If) of up to 20 mA and a forward voltage (Vf) of 1.2 V. The component is housed in a 6-SMD Gull Wing surface-mount package.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'XPLF' against the manufacturer's latest datasheet to confirm pinout, lead finish, and RoHS compliance status. Check for active production status or obsolescence notices, as availability may be limited. Ensure the selected distributor provides genuine components with traceable origin documentation to avoid counterfeit risks.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize electrical noise in AC power control systems. The 600 V blocking voltage suits standard mains voltage applications. Verify that the 100 mA load current meets the target application requirements. Consider the SMD package type if space constraints dictate surface-mount technology over through-hole alternatives.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp's PC3SD series of phototriac optocouplers. The series is designed for general-purpose AC switching applications requiring galvanic isolation. The specific model integrates zero-crossing detection, distinguishing it from non-zero-crossing variants within the same family. It serves as a interface between low-voltage logic circuits and high-voltage AC loads.
