YFZVFHTR3.6B Discrete Semiconductor Products

Introduction

The YFZVFHTR3.6B is a single Zener diode with a breakdown voltage of 3.6V. It helps prevent excessive current from flowing in circuits. Zener diodes are characterized by the low turn-on voltage and the high reverse breakdown voltage. The YFZVFHTR3.6B can be used in the design of high-efficiency voltage regulation and overvoltage protection circuits.

Applications and Working Principle

The YFZVFHTR3.6B is typically used in voltage regulators, voltage protection circuits and general-purpose protection circuits. It is mainly used to control the flow of current in a circuit, thus protecting devices from over-voltage and over-current. When a voltage exceeds the breakdown voltage of the Zener diode, the Zener diode will conduct current and limit the voltage across the device.

A Zener diode works by using the "reverse breakdown" phenomenon. This phenomenon occurs when, due to the bandgap engineering, an electric field is produced inside the diode that is greater than the electric field associated with the junction breakdown voltage. This causes the diode to function in the breakdown region and current to flow through it, limiting the voltage applied across the diode.

The potential difference between the anode and the cathode is referred to as the Zener voltage. The Zener voltage of the YFZVFHTR3.6B is 3.6V, which means that the diode will start conducting current when there is a potential difference of 3.6V or more between the anode and the cathode.

Additional Considerations

When choosing a Zener diode, an important consideration is its power rating, which is the maximum power that the diode can dissipate without being damaged. Careful consideration should also be given to the thermal resistance of the diode, as this affects the diode’s ability to dissipate the heat generated by the current flowing through it.

The YFZVFHTR3.6B has a maximum power rating of 500mW, which is sufficient for most applications. It also features a thermal resistance of 10K/W, which is lower than the thermal resistance of most Zener diodes. As a result, the YFZVFHTR3.6B can dissipate heat more effectively, which in turn reduces the risk of thermal damage caused by excessive current.
