Introduction:

FLZ8V2B is a single Zener diode from the STMicroelectronics product range. It is designed for voltage reference and reverse voltage protection applications. The diode can provide a zener voltage of 8.2 Volts and features a wide working temperature range and a low leakage current. Due to its low on-state voltage drop, it is also suitable for low-dropout regulation.

Application Field:

FLZ8V2B diodes are suitable for many applications, including:

• Voltage reference and reverse voltage protection in automotive and portable electronics
• Voltage clamping and voltage regulation in AC or DC circuits
• AC or DC linear regulation with low input-output voltage drop
• Reverse polarity protection in switching power supply

Working Principle:

The FLZ8V2B diode operates on the Zener principle, where the breakdown voltage is determined by the Zener voltage and the Zener voltage is determined by the doping level of the intrinsic layer of the diode. When a forward voltage is applied to the diode, the holes and electrons are forced to cross the junction, resulting in a current that increases with voltage. When the forward voltage reaches the Zener voltage of the diode, the reverse current increases sharply and the voltage across the diode is limited to the Zener voltage.In practice, the FLZ8V2B diode is used to provide a reference voltage for applications where an accurate reference voltage is required. It can also be used to provide reverse voltage protection to protect downstream components from over-voltage or reverse polarity conditions. This diode is also suitable for use in AC or DC linear voltage regulation as its low on-state voltage drop allows for low input–output voltage drops.

Conclusion:

FLZ8V2B is a single Zener diode from STMicroelectronics designed for voltage reference, reverse voltage protection and low-dropout regulation in automotive and portable electronics applications. It features a zener voltage of 8.2 Volts and a wide operating temperature range. Its low leakage current and low on-state voltage drop make it suitable for low-dropout voltage regulation. This diode operates on the Zener principle, where the breakdown voltage is determined by the Zener voltage.
