APPLICATIONS OF THE MOC3011 TRIAC DRIVER

This is usually not a problem, except in unusually noisy environments, because the and its triac will commute off at the next zero crossing of the line voltage, and most loads are not noticeably affected by an occasional single half-cycle of applied power. In some cases, this may require two snubbers-one for the triac and one for the. A 4-bit address code determines. This is not quite enough to drive the MOC, nor can it be connected directly to an SCR or triac, because computer common is not normally referenced to one side of the ac supply. Application note AC switch triggering with 3.

The is used to help protect sensitive digital or analog input circuits on data, More information. Featuring very high commutation levels and high surge current applicagions.

This is usually not a problem, except in unusually noisy environments, because the and its triac will commute off at the next zero crossing of the line voltage, and most loads are not noticeably affected by an occasional single half-cycle of applied power.

Currents higher than 15 ma do not improve performance and may hasten the aging process inherent in LED’s.

The appllcations has a minimum blocking voltage of Vdc in either direction in the off state. The resistor should be chosen to set the current into the LED to be a minimum of 10 ma but no more than 50 ma.

An example is shown in Figure 8. There are numerous ways to increase this current to a level compatible with the input requirements; an efficient way is applicattions use the Fairchild TinyLogic, NC7SZ0 shown in Figure 5. Device summary 4 A Triacs Datasheet production data. On the simply connecte The detector has a minimum blocking voltage of 50 Vdc in either direction in the off state. The motor is driven by a circuit mounted near the motor and More information.

Application Notes: TRIAC Driver Optocouplers

The main restriction is that the triac must be properly chosen to sustain the proper inrush loads. Application note AC switch triggering with 3. Rotron Technical Products Division. When the designer has more control of the input and output conditions, he can eliminate those components which are needed for his particular application to make the circuit more cost effective.

This is usually not a problem, except in unusually noisy environments, because the MOC and its triac will commute off at the next zero crossing of the line voltage, and most loads are not noticeably affected by an occasional single half-cycle of applied power.

To reduce system disturbances it is therefore essential. Assuming the forward drop to be 1. In the on state, the detector will pass mA in either direction with less than 3 V drop Figure 1. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.

The is a quad array of transient voltage clamping circuits designed to suppress ESD and other transient over-voltage events.

On the other hand, care should be taken to ensure that the maximum LED input current 50 mA is not exceeded or the lifetime of the MOC rtiac be shortened. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
