The diode should satisfy the following requirements:
Peak reverse-breakdown voltage must be at least 3 times the load voltage.
Average rectified current must be 1 A.
Inrush Current Considerations
When a relay or transistor output is used to switch a load with a high inrush cur-
rent such as an incandescent lamp, suppress the inrush current as shown
below.

Countermeasure 1
Providing a dark current of
approx. one-third of the rated
value through an incandescent
lamp
Countermeasure 2
Providing a limiting resistor

Fuse Insertion
The CPM2B with transistor output may burn if the load is short-circuited, there-
fore, insert a protective fuse in series with the load.
