H11C5

Triac, SCR Output Optoisolators Overview

The onsemi H11C5 is a single-channel optocoupler featuring an infrared LED input and a photo-SCR output. It utilizes a 6-pin MDIP or PDIP package for through-hole mounting. Key electrical parameters include a maximum forward voltage of 1.2V, a peak forward current of 60mA, and a maximum continuous output current of 300mA. The device offers a high isolation voltage of 5300Vrms and operates within a temperature range of -55°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a photo-SCR output stage suitable for direct AC load control applications
• Provides robust galvanic isolation with a 5300Vrms dielectric strength rating
• Designed for through-hole mounting in standard 6-pin DIP configurations

Triac, SCR Output Optoisolators Applications

• Solid-state relays for switching AC loads
• Industrial motor drive control circuits
• Power supply feedback loops requiring SCR triggering

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., M) against the datasheet to confirm package type and compliance status. Confirm availability as some variants may be discontinued or subject to allocation. Ensure the selected component meets the required isolation voltage ratings for the target application safety standards.

Triac, SCR Output Optoisolators Selection Notes

Select this component when an SCR output is required for driving triacs or SCRs directly. Compare the 5300Vrms isolation rating against system requirements. Consider the 300mA continuous output current limit for load sizing. Verify thermal management needs given the operating temperature range up to 100°C.

Triac, SCR Output Optoisolators Part Context

The H11C5 belongs to the H11C series of optocouplers from onsemi. This family is designed for general-purpose isolation and control applications. It shares the same input structure as other H11C variants but differs in its output device type, specifically utilizing a silicon-controlled rectifier instead of a phototransistor.

Triac, SCR Output Optoisolators Replacement Considerations

Check for H11C5M or equivalent pin-compatible alternatives from other manufacturers. Verify that replacement parts maintain the 5300Vrms isolation and 300mA SCR output current capabilities.
