FLZ39VD Discrete Semiconductor Products

Diodes - Zener - Single

FLZ39VD is a single-line Zener diode. It has a 3.9 V Zener voltage, 40 V Zener power rating and an average power dissipation of 0.5 W. This Zener diode also has a high breakdown voltage, a low reverse current and a very low forward voltage. This makes it suitable for a wide range of applications.

Application Field

FLZ39VD can be used in many different areas. Some of the most common applications include regulating current when the voltage is reversed and protecting against power surges. It is typically used in preregulator circuits, overcurrent protection circuits, voltage-clamp circuits and TVS (Transient Voltage Suppressor) circuits. This Zener diode can also be used in microcontrollers, current supplements, voltage references, linear regulators and power amplifiers. It is also often used in control circuits on telecoms, medical, aerospace and automotive equipment.

Working Principle

The working principle of FLZ39VD is based on a Zener breakdown. The Zener breakdown occurs when a certain amount of electric field or voltage is applied to the diode. This causes a reversed current flow, which is known as the Zener current. This current flow causes the voltage to remain steady, allowing the diode to function as a voltage regulator and protect against power surges. The diode also has a low forward voltage and a low reverse current, which makes it suitable for many applications.
