PC4SF11YVZAF

Triac, SCR Output Optoisolators Overview

The PC4SF11YVZAF is a Triac and SCR output optocoupler manufactured by Sharp Microelectronics. It features a PhotoTriac output without a zero-crossing circuit, housed in a PDIP-6 package for through-hole mounting. Key electrical parameters include an isolation voltage of 5000 Vrms, a maximum repetitive peak off-state voltage (VDRM) of 600 V, and a maximum continuous output current of 100 mA. The device operates with a forward current of up to 50 mA and has a maximum trigger current of 10 mA. It supports a wide operating temperature range from -30°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• Provides reinforced electrical isolation between input and output circuits via an internal LED and PhotoTriac structure.
• Features a non-zero-crossing output design suitable for phase control applications requiring immediate response to input signals.
• Offers high voltage blocking capability with a 600 V off-state rating and robust 5000 Vrms insulation strength.

Triac, SCR Output Optoisolators Applications

• Solid state relays for AC load switching
• Motor speed control circuits
• Lighting dimmer controls

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity due to potential availability issues or end-of-life status. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions meet manufacturer specifications to prevent moisture damage prior to soldering. Review latest datasheet revisions for any parameter updates before finalizing design integration.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-angle control is required rather than zero-crossing switching. Ensure the load current does not exceed the 100 mA continuous rating. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the application. Consider thermal management if operating near the upper temperature limit.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp's PC4SF series of optocouplers designed for general-purpose AC switching. It shares the same package footprint as other variants in the family but differs in internal circuitry, specifically lacking the zero-crossing detector found in models like the PC4SF21. It serves as a direct functional alternative to older discrete triac-driver combinations.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include PC4SF11YVZBF or PC4SF11YVZCF within the same Sharp family, provided they match the specific trigger current and voltage ratings required by the design. Cross-brand replacements require careful verification of isolation voltage and package dimensions.
