MOC3021 Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the MOC3021 is -40°C to 85°C.

  • To ensure reliability in high-temperature applications, it is recommended to derate the device's current and voltage ratings according to the temperature derating curve provided in the datasheet.

  • The maximum allowable voltage for the MOC3021 is 80V, but it is recommended to operate the device at a voltage below 60V to ensure reliable operation.

  • The correct resistor value can be calculated using the formula: R = (Vcc - Vf) / If, where Vcc is the supply voltage, Vf is the forward voltage of the LED, and If is the desired LED current.

  • The typical response time of the MOC3021 is around 1-2 microseconds, but this can vary depending on the specific application and operating conditions.
