H11J2SM

Triac, SCR Output Optoisolators Overview

The H11J2SM is a single-channel optoisolator manufactured by onsemi, distributed by Isocom Components. It features an infrared LED input paired with a triac output, providing electrical isolation rated at 5300Vrms. The device is housed in a 6-SMD surface-mount package with an鸥翼 (gull-wing) configuration. Key electrical specifications include a maximum forward current of 60 mA and a peak repetitive off-state voltage of 400 V for the output triac. The unit operates within a temperature range of -40°C to 100°C and supports DC input control.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a gallium arsenide infrared emitting diode with a zero-crossing triac detector for noise-immune switching.
• Provides high-voltage galvanic isolation between input and output circuits to protect low-voltage control logic.
• Features a microprocessor-compatible design suitable for digital signal interfacing applications.

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) driver circuits
• AC power switching control interfaces
• Industrial motor control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer marking on the component body, as Isocom Components often distributes products from major manufacturers like onsemi. Confirm the specific suffix 'SM' corresponds to the correct 6-SMD gull-wing package variant required for your PCB footprint. Ensure the datasheet version matches the production batch for accurate isolation voltage ratings.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing detection is required to minimize electromagnetic interference during AC load switching. Compare the 5300Vrms isolation rating against system safety requirements. Consider the 60 mA maximum forward current limit when designing the input series resistor network to ensure reliable triggering without exceeding device limits.

Triac, SCR Output Optoisolators Part Context

This part belongs to the H11Jxx family of optocouplers featuring triac outputs. The 'H11J' designation typically indicates a zero-crossing triac output type, distinguishing it from non-zero-crossing variants like the H11L series or transistor-output H11A series. The 'SM' suffix denotes the surface-mount package style.
