S22MD3

Triac, SCR Output Optoisolators Overview

The Sharp Microelectronics S22MD3 is a dual-channel SCR output optocoupler designed for high-voltage isolation applications. It features an 8-DIP package and provides 2500 Vrms insulation voltage between input and output circuits. The device incorporates two independent phototriac outputs, each capable of handling a peak off-state voltage of 600V. Key electrical characteristics include a maximum forward current of 10mA for the LED trigger and a holding current of 1mA. This component is suitable for industrial control systems requiring reliable galvanic isolation.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific datasheet revision and pinout compatibility before integration. Confirm that the 2500 Vrms isolation rating meets your safety standards. Ensure thermal management aligns with the 600V off-state voltage requirements. Check for any obsolescence notices or lifecycle status updates from Sharp Microelectronics prior to finalizing procurement plans.

Triac, SCR Output Optoisolators Selection Notes

Select the S22MD3 when dual-channel isolation is required in a compact DIP format. It is appropriate for applications needing 600V blocking capability with low trigger current. Consider alternative packages if surface-mount technology is preferred. Evaluate the 1mA holding current against your load requirements to ensure reliable latching behavior in the target circuit design.

Triac, SCR Output Optoisolators Part Context

This component belongs to Sharp Microelectronics' family of SCR output optocouplers. It shares functional similarities with other models like the S2S series but differs in channel count and package type. The S22MD3 specifically addresses needs for dual isolated channels in traditional through-hole designs, distinguishing it from single-channel or surface-mount variants in the broader product lineup.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other Sharp dual-channel SCR optocouplers with matching 2500 Vrms ratings. Verify pin-to-pin compatibility with existing PCB layouts. Cross-reference specifications such as holding current and off-state voltage to ensure equivalent performance in critical isolation applications.
