Alternate Parts for MOC8021
This table gives cross-reference parts and alternative options found for MOC8021. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of MOC8021, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
MOC8021 Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for the MOC8021 is -40°C to 85°C, although it can withstand storage temperatures from -50°C to 150°C.
-
To ensure proper isolation, make sure to follow the recommended PCB layout and creepage distance guidelines, and use a suitable insulation material between the input and output circuits.
-
The maximum allowable voltage across the input and output pins is 5300Vrms for 1 minute, and 1414Vrms for continuous operation.
-
The LED current in the MOC8021 should be limited to 10mA to ensure reliable operation and prevent damage to the device.
-
The MOC8021 is suitable for high-frequency applications up to 100 kHz, but the user should ensure that the device is properly bypassed and decoupled to prevent oscillations and noise.
