MOCZ500

OPTOISOLATOR ZERO CROSS TRIAC OUTPUT

Motorola => Freescale 

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 resis-

tive 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.
