Surge Protection

When connecting to digital outputs a load that may generate a voltage surge or current, for example an

inductive load such as a relay coil or incandescent lamp, suitable protection measures are required to

prevent damage to the output stage or malfunction owing to noise. The instantaneous interruption of

current flowing through a coil, including a relay ,results in the sudden generation of a high-voltage pulse.

If the voltage exceeds the withstand voltage of the transistor, the transistor performance may be

degraded or the transistor may be damaged. To prevent this, be sure to connect a surge absorption

element when driving an inductive load including a relay coil. Examples of measures against voltage

surge are shown in Figure 3.7. below.

CAUTION

The protection circuit must be installed less than 50 cm from the load and contact to provide

effective protection.
