INPUT The input LED is connected to a d rive circuit, consisting of a power source and a limiting resistor (R IN). Assuming 5V as the supply, calculating a value for RIN can be determined by following: = 3.5V / 0.010A ≈ 350 Ω In the above calculation, an LED drop of 1.5V and desired I F of 10mA are used. Referencing the “Input Specifications” on p age 2, the typical drop across the LED is 1.4V and the maximum drop is 1.8 V. For a more precise resistor value across all expected tempe rature option, the “VIN vs. Temperature” curve (Figure 05 on page 4) can be referenced. OUPUT The output terminals (MT1 & MT2) are connected to an AC load, w ith maximum peak voltage (V L) of 400V and maximum continuous current (IL) of 0.8 amps. The load must be derated according to temperatur e, and a derating curve can be found in Figure 04 on page 4. Typical loads may include resistive or inductive loads. Examples of resistive loads include: Light Dimming Controls (home / office / industrial lighting) Heating Element Controls (rice cookers / deep fryers) Examples of inductive loads include: Motor Controls (air conditi oning blowers / fan control) Valve Controls (washing machine water flow pumps, gasoline pum ps) In general, the STZ8042 can be used in many industrial and home appliance applications where hi gh voltages (up to 400V peak) a nd loads of up to 0.8A are being switched. SNUBBER CIRUIT A snubber circuit (outlined in above diagram) may be added when high levels of noise and / or surge are expected from the load. These are often found in highly inductive loads and can lead to an “i nductive kick” which may potentially damage components in the c ircuit. The snubber circuit consists of a resistor (R S) and a capacitor (C S) which together help dissipate charge buildup across the load. Values fo r RS and CS are dependent upon the load and SSO engineering support can help determine appropriate values if needed.
