MOC3053SR2M

Triac, SCR Output Optoisolators Overview

The MOC3053SR2M is a Triac and SCR output optocoupler manufactured by onsemi, designed for surface-mount applications. It features a PhotoTriac output without a zero-crossing circuit, providing random phase control capabilities. The device offers an isolation voltage of 4170 Vrms and supports a maximum off-state voltage (VDRM) of 600 V. Key electrical parameters include a maximum forward current of 60 mA, a typical forward voltage of 1.18 V, and a power dissipation rating of 330 mW. It operates within a temperature range of -40°C to +85°C and has a minimum static dv/dt capability of 1 kV/µs.

Triac, SCR Output Optoisolators Feature Summary

• Enhanced static dv/dt capability ensures stable switching performance for inductive loads.
• Random phase operation allows triggering at any point in the AC cycle due to the absence of a zero-crossing circuit.
• High isolation voltage provides robust electrical separation between input and output circuits.

Triac, SCR Output Optoisolators Applications

• Switching inductive loads requiring random phase control
• Industrial motor control systems
• Solid-state relay designs

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SR2M' against the official onsemi datasheet to confirm package type and tape/reel specifications. Ensure compatibility with RoHS directives and check for recent Product Change Notifications regarding assembly or material declarations before finalizing procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triac driving is required rather than zero-crossing switching. Consider the 600 V blocking voltage and 1 kV/µs dv/dt rating for high-noise environments. Verify that the SMD-DIP-6 footprint fits the PCB layout constraints and that the thermal dissipation requirements are met within the operating temperature range.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC305xM series of Triac and SCR output optocouplers from onsemi. It shares the same family characteristics but differs in packaging and specific electrical tolerances compared to through-hole variants like the MOC3052. The series is widely used for isolating low-voltage control signals from high-voltage AC power lines.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's cross-reference guide for potential alternatives if this specific SMD variant is unavailable.

Triac, SCR Output Optoisolators FAQ

Does the MOC3053SR2M include a zero-crossing detection circuit?

No, the MOC3053SR2M does not include a zero-crossing circuit, allowing for random phase triggering.
