The device can also be used as a free-wheeling diode in auto-sensing flyback converters.

Working Principle

The 3SMBJ5918B-TP Zener diode works by allowing current to flow in one direction, while blocking current from flowing in the opposite direction. When current passes through the device it creates a voltage drop across the junction. When the reverse voltage exceeds the breakdown voltage, current flows in the reverse direction. This allows the device to limit the voltage to a safe level when an overvoltage condition is detected. This can help to protect sensitive components from damage due to excessive current or voltage.

The 3SMBJ5918B-TP Zener diode is a reliable and cost-effective solution for a variety of protection applications in consumer electronics and power supplies. It is easy to install and maintain and is capable of providing efficient current flow. The device is ideal for clipping and suppression applications, providing protection against overvoltage conditions.
