MOC3010

Triac, SCR Output Optoisolators Overview

The MOC3010 is a 6-pin DIP random-phase optoisolator featuring a triac driver output. It integrates a gallium arsenide infrared emitting diode with a silicon bilateral switch, designed for isolated AC switching applications. Key electrical parameters include a peak off-state voltage of 250 V, a maximum forward current of 60 mA, and an isolation voltage rating of up to 7500 V peak. The device operates within a temperature range of -40°C to +85°C and requires no zero-crossing circuitry, allowing for phase-angle control.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific manufacturer source, as the MOC3010 series has been discontinued by Fairchild Semiconductor and may be listed as obsolete or not in production. Confirm that the datasheet provided corresponds to the original Motorola or Fairchild specifications rather than third-party generic equivalents. Ensure the package type matches the required 6-pin DIP form factor for the target design.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero-crossing random-phase triggering is required for AC load control. It is appropriate for applications needing moderate isolation voltages and small footprint solutions. Consider alternative devices if zero-crossing operation or higher voltage ratings are necessary. Verify compatibility with the driving circuit's current requirements against the specified forward current limits.

Triac, SCR Output Optoisolators Part Context

The MOC3010 belongs to a family of 6-pin DIP random-phase optoisolators originally developed by Motorola and later produced by Fairchild Semiconductor. These devices are designed to replace traditional mechanical relays in AC switching applications. The series includes variants with different voltage ratings, such as the MOC3011 and MOC3012, offering flexibility for various isolation and voltage requirements.
