PDZVTR4.7A is a single zener diode created by STMicroelectronics. The letter “P” in PDZVTR4.7A stands for “power”. It is designed for use in applications requiring low power dissipation and high current, such as surge and transients suppression.

The PDZVTR4.7A is designed to provide output configured as a “Zener” diode. This feature is used to provide low and medium voltage protection against voltage transients and overvoltage stress. Unlike other diodes, the PDZVTR4.7A is designed to not short circuit when exposed to higher voltages than its nominal voltage.

The PDZVTR4.7A is a single zener diode with a reverse zener breakdown voltage of 4.7 V. This feature makes the diode less susceptible to electrical transients. The PDZVTR4.7A also features a Zener impedance of 400 mΩ maximum at 5.0 V and a low capacitance of 3.7 pF. The diode has a small size of 0.9mm x 1.1mm and a height of 0.4mm. This means that the diode can be used in many applications and provides a great solution for space-constrained design.

The PDZVTR4.7A can be used in a variety of applications, including digital power supplies, voltage clamping, overvoltage protection, and reverse-polarity protection. The diode also has several features that make it ideal for low-power, low-noise, and high reliability applications. Its low on-state voltage drop makes it ideal for low power dissipation, and its forward voltage drop is very low, making it suitable for high efficiency designs. The diode is also low noise, making it suitable for low-noise audio applications.

The PDZVTR4.7A is designed to provide a high level of protection against different electrical transients. The diode can absorb electrostatic discharges (ESDs) of 4000 V, which is more than enough to protect sensitive electronic components. The diode also has a peak surge current of 80 A at 10 µs, which is more than enough to protect sensitive components from voltage transients.

The working principle of a PDZVTR4.7A is simple. The diode acts as a voltage regulator by allowing current to flow in one direction while blocking or clamping current in the other direction. When the diode is exposed to a voltage higher than its breakdown voltage, the excess voltage is blocked, effectively creating a regulated voltage.

In summary, the PDZVTR4.7A is a single zener diode created by STMicroelectronics. It is designed to provide output configured as a “Zener” diode, with a reverse zener breakdown voltage of 4.7 V and a Zener impedance of 400 mΩ maximum at 5.0 V. The diode can be used in a variety of applications, including digital power supplies, voltage clamping, overvoltage protection, and reverse-polarity protection. The working principle of the PDZVTR4.7A is that it acts as a voltage regulator, allowing current to flow in one direction while blocking or clamping current in the other direction.
