SMBJ4754E3/TR13

Zener diodes have a unique ability to conduct current in one direction like a normal diode, but also in the reverse direction when the voltage has reached its "breakdown" threshold. The SMBJ4754E3/TR13 is one such diode.

The SMBJ4754E3/TR13 is a single zener diode. It has a unidirectional maximum reverse voltage of 47V, a forward voltage of 35V, and a maximum power dissipation of 500mW and a maximum reverse current of 500μA. It has an operating temperature range from -65°C to +175°C, making it suitable for a variety of applications.

This diode is often used in voltage regulation circuits, which are used to convert a higher input voltage to a lower output voltage. The diode acts as a voltage reference and helps maintain a steady output voltage, despite any fluctuations or spikes in the input voltage. This is important in electronic circuits, as fluctuations or spikes can lead to malfunction and damage.

The SMBJ4754E3/TR13 has a very specific working principle. When forward current is applied, it acts as a normal diode, allowing current to flow from anode to cathode. When the applied voltage reaches the breakdown voltage, the diode begins to conduct current in the reverse direction. This reverse current regulates the output voltage and helps maintain a steady voltage even with fluctuations or spikes in the input voltage.

Due to its high efficiency, low cost and wide operating temperature range, the SMBJ4754E3/TR13 is suitable for a number of applications, such as voltage regulators, protection circuits, and low voltage power supplies, among others. If you are looking for an efficient and reliable zener diode, then the SMBJ4754E3/TR13 is an excellent choice.
