MOC3073SVM

Triac, SCR Output Optoisolators Overview

The MOC3073SVM is a Triac and SCR output optocoupler manufactured by onsemi. It features a single channel phototriac output without a zero-crossing circuit, designed for surface mount (SMD/SMT) installation in a PDIP-6 package. The device supports an isolation voltage of 4170 Vrms and offers a peak blocking voltage (Vdrm) of 800 V. Electrical characteristics include a maximum forward current (If) of 60 mA, a forward voltage (Vf) of 1.18 V, and power dissipation of 330 mW. Operating temperature ranges from -40°C to +85°C.

Triac, SCR Output Optoisolators Feature Summary

• Power supply circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compliance with relevant safety standards such as UL1577 and DIN EN/IEC60747-5-5 for the intended application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triac triggering is required rather than zero-crossing switching. Consider the 800 V peak blocking voltage and 4170 Vrms isolation rating for high-voltage isolation requirements. Evaluate the SMD packaging constraints and thermal dissipation limits relative to the system's operating temperature range of -40°C to +85°C.

Triac, SCR Output Optoisolators Part Context

The MOC3073SVM belongs to the MOC307x series of Triac driver optocouplers. This family provides galvanic isolation between control circuits and high-power AC loads. The 'SVM' suffix typically denotes the surface mount variant within the standard DIP-6 form factor, distinguishing it from through-hole equivalents in the same functional family.

Triac, SCR Output Optoisolators Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that alternative components match the 800 V Vdrm rating, 60 mA If limit, and random-phase functionality. Ensure pinout compatibility and equivalent isolation voltages are maintained during replacement.
