APPLICATION CONSIDERATIONS

Input Drive Circuit

The MOCZ500 SSR is guaranteed to trigger with an input current of 10 mA at 25°C. This trigger current increases with lower ambient temperatures as shown on Figure 3 Forward Trigger Current (IFT) versus Ambient Temperature.

When the input drive circuit is capable to supply the MOCZ500 input LED trigger current, only a current limiting resistor in series with the LED is required. TTL, DTL and microcontrollers with enhanced current capability output ports are able to meet this requirement.

Most CMOS logic circuits and Microcontroller output ports are not rated to sink or source currents required to trigger the MOCZ500. In this case a drive circuit is required as shown in Figure 10 or a TTL buffer interface circuit as shown in Figure 9.

VCC

TTI/DTL

R1 for VCC (low) 4.5 V, IFT = 10 mA, VF LED = 1.2 V, VOL = 0.5 V R1 = (4.5 V ± 1.2 V ± 0.5 V): 10 mA = 280 Ω

Choose 270 Ω

Figure 9. Input Drive Circuit

Snubber Circuit

Snubberless operation of resistive loads is possible, but snubbers are recommended for all applications. A typical application is shown in Figure 11. The snubber attenuates the high kickback voltages and commutating dv/dt generated by inductive loads during the turn off of the SSR. It also protects the SSR from line transients generated elsewhere within the equipment (for example inductive loads switched by mechanical contacts such as relays manual on/off switches etc.) or outside the equipment such as air conditioners, electrical heaters and motors.

Snubbers are also necessary to pass noise immunity tests such as IEC1000 4±4 for fast transients. In this test fast rising high voltage spikes are superimposed onto the line voltage to simulate AC line transients.

Switching Loads with Currents Below the Minimum Current Rating

The MOCZ500 is capable to switch any inductive or resistive load within its rating of minimum 30 mA and a maximum of 500 mA RMS.

MOCZ500

At operating currents below the minimum specified value the Power triac remains in the off state and the triac driver carries the current. This may cause a problem, because the triac driver has a significant lower commutating dv/dt than the power triac. For loads below 30 mA AC rms a snubber is mandatory. Evaluations with various low current inductive and resistive loads concluded that a snubber of R = 100 Ω and C = 10 nF is sufficient.
