S11MD5P

Triac, SCR Output Optoisolators Overview

The S11MD5P is a single-channel phototriac output optocoupler manufactured by Sharp Microelectronics. It features a 6-SMD surface-mount package and provides electrical isolation with an insulation voltage of 5000 Vrms. The device includes an internal triac output capable of handling a maximum continuous output current of 100 mA and a peak off-state voltage (VDRM) of 800 V. It operates without a zero-crossing circuit, allowing for phase control applications. The input side utilizes an infrared LED with a forward current rating of 50 mA and a typical forward voltage of 1.2 V. The component is designed for through-hole or surface-mount integration depending on the specific variant configuration, though this model specifies SMD packaging.

Triac, SCR Output Optoisolators Procurement Notes

Verify the exact package type and pinout configuration against the official datasheet before procurement, as surface-mount variants may differ from through-hole equivalents. Confirm RoHS compliance status and lifecycle stage, as some listings indicate obsolete status. Ensure the supplier provides genuine Sharp Microelectronics components to avoid counterfeit risks associated with legacy semiconductor parts.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-control functionality is required rather than zero-crossing switching. The 5000 Vrms isolation rating suits industrial environments requiring robust safety barriers. Consider the 6-SMD footprint constraints during PCB layout. Verify that the load current does not exceed the 100 mA continuous limit and that the gate trigger requirements align with the driving circuit capabilities.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp Microelectronics' family of triac output optocouplers, designed for AC power control. It serves as a bridge between low-voltage logic circuits and high-voltage AC loads. The series typically offers various packaging options, including DIP and SMD, to accommodate different manufacturing processes. These devices are commonly used in appliances and industrial equipment for safe isolation and control.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct replacements such as PC4SD11NTZCF if through-hole packaging is preferred instead of SMD. Verify compatibility with existing PCB footprints and thermal management requirements when substituting. Ensure the replacement maintains the same isolation voltage and output current ratings to preserve system safety and performance.
