This document introduces the features and characteristics of MOC3031M, MOC3032M, MOC3033M, MOC3041M, MOC3042M, MOC3043M 6-Pin DIP Zero-Cross Optoisolators Triac Driver Output (250/400 Volt Peak) products.
The MOC303XM and MOC304XM series are 6‑pin DIP optoisolators that combine an AlGaAs infrared LED with a silicon detector to provide zero‑cross detection and triac driver functionality. They are intended for interfacing logic circuits with 115 VAC loads such as solenoids, lighting, motor drives, and solid‑state relays.
The document lists absolute maximum ratings, electrical characteristics, typical application circuits, package dimensions, ordering options, and marking information. It also includes recommended LED trigger currents for each model and notes that the device is a trigger element only, not a load driver. This manual is written in Chinese.
| Isolation Surge Voltage (VISO) | 7500 Vac(pk) |
|---|---|
| Emitter Continuous Forward Current (IF) | 60 mA |
| Reverse Voltage (VR) | 6 V |
| Typical dv/dt rating | 2000 V/µs typical, 1000 V/µs guaranteed |
| LED Trigger Current (IFT) – MOC3031M / MOC3041M | 15 mA |
The isolation surge voltage is rated at 7500 Vac peak.
No, the device is intended only as a trigger element and should not drive a load directly.
Typical dv/dt is 2000 V/µs, with a guaranteed minimum of 1000 V/µs.
