Piezoelectric Sounders FAQ QAre there any precautions to be taken when driving with an IC?

A

Please do not drop the body of the device, subject it to shocks, or change its temperature.
That may cause an electric charge (surge voltage) to be generated and destroy the IC or other components.
There is a method that uses a Zener diode as in Fig. 1 as an example to protect against that.
