STZ8063 Connection (Wiring) Diagram

Snubber Circuit

Refer to the above figure as an example of a typical wiring diagram for the STZ8063.

INPUT

=

(5V – 1.5V) / 0.010A

=

3.5V / 0.010A

≈

350 Ω

typical drop across the LED is 1.4V and the maximum drop is 1.8V. For a more precise resistor value across all expected temperature

OUPUT

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 conditioning blowers / fan control)



Valve Controls (washing machine water flow pumps, gasoline pumps)

In general, the STZ8063 can be used in many industrial and home appliance applications where high voltages (up to 600V peak) and

loads of up to 1.2A 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 “inductive kick” which may potentially damage components in the circuit. The
