Make sure that the heat sink is secured to the chassis. 2) Ground the radiation fin so that there will be no difference in electric potential between the radiation fin and ground. 3) The thermal protection circuit operates at a Tj of approximately 150°C. The thermal protection circuit is reset automatically when the temperature drops. 4) The overvoltage protection circuit operates at a Vcc of approximately 28V. 5) Use a stabilised power supply with a 3V or higher standby voltage.
