PC3SF11YXPBF

Triac, SCR Output Optoisolators Overview

The PC3SF11YXPBF is a single-channel phototriac output optocoupler manufactured by Sharp Microelectronics. It features an infrared emitting diode coupled to a triac output for non-zero-crossing switching applications. The device provides high isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum repetitive peak off-state voltage (VDRM) of 600 V and a maximum continuous on-state current (IT(RMS)) of 100 mA. The input forward current (If) is specified at 50 mA, with a maximum trigger current (Ift) of 7 mA. It operates within a temperature range of -30°C to +100°C and is housed in a surface-mount SMD package.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'XPBF' against official Sharp Microelectronics documentation to confirm pinout compatibility and RoHS status. Ensure the selected variant matches the required surface-mount package type for your PCB layout. Cross-reference datasheet revisions to confirm parameter stability before finalizing component selection for production.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero-crossing operation is required for precise phase-control applications. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the target AC system. Confirm that the 100 mA RMS current rating exceeds the maximum load current. Ensure the 5000 Vrms isolation rating satisfies safety standards for the application environment.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp's PC3SF series of phototriac couplers designed for general-purpose AC switching. Unlike zero-crossing variants, this model allows for immediate turn-on upon signal receipt, making it suitable for applications where timing precision relative to the AC waveform is critical. It serves as a standard interface between low-voltage logic and higher-power AC circuits.

Triac, SCR Output Optoisolators Replacement Considerations

Direct replacements must match the 600 V VDRM, 100 mA IT(RMS), and non-zero-crossing functionality. Verify pinout compatibility for the specific SMD package. Alternative parts from other manufacturers require validation of isolation voltage and trigger current specifications to ensure circuit performance parity.

Triac, SCR Output Optoisolators FAQ

Does the PC3SF11YXPBF include a zero-crossing detection circuit?

No, this component is a non-zero-crossing phototriac coupler. It triggers immediately when the input LED is activated, regardless of the AC line voltage phase.

What is the maximum repetitive peak off-state voltage for this device?

The maximum repetitive peak off-state voltage (VDRM) is 600 V, allowing it to block high voltages typical of mains-powered applications.
