General Notes
1) All parameters at 25°C unless otherwise specified.
2) Low current loads and high ambient temperature can affect turn-on time.
3) 8 VDC Minimum control voltage. Resistive loads only. Consider switching losses; at maximum frequency reduce to 75% output current. Recommended suppreor diode connected at load side, see wiring diagram.
4) Increase minimum voltage by 1 V for operations from -20 to -40°C.
5) Minimum spacing to obtain max. current is 22.5mm between adjacent units
