Key Features

  • Minimum Sound Pressure Level: Provides a minimum sound pressure level of 85dB at 10cm at the rated operating condition.
  • Digital ON/OFF Control: The buzzer can be activated by applying a HIGH logic level to the SIGNAL pin and deactivated by applying a LOW logic level.
  • Active Magnetic Buzzer: Generates an audible tone when enabled without requiring an external audio-frequency PWM signal.
  • Freewheeling Diode: Helps protect the MOSFET from voltage spikes when the buzzer is switched off.
  • 3.3V and 5V Logic Control: Compatible with common 3.3V and 5V microcontroller control signals.
