Surge Voltage Countermeasures

When connecting a load that generates surge voltages and inrush currents, such as an induction load

(relay coil) or an incandescent light bulb, to the control output signals, appropriate protection must be

provided in order to prevent damage to the output stage or a malfunction due to noise. The rapid

shutoff of a coil, such as a relay, generates a sudden high-voltage pulse. If this voltage exceeds the

voltage tolerance level of the output transistor, it can cause the transistor to gradually deteriorate, or

even completely damage the transistor. Therefore, when driving an induction load, such as a relay coil,

you should always connect a surge-absorbing device. The following illustrates a surge voltage

countermeasure that can be employed:

CAUTION

In order for a protection circuit to operate effectively, it must be connected within 50cm of a load

and a contact point.
