The PTV5.6B-E3/85A diode is a single Zener diode with a breakdown voltage of 5.6 volts. It has a low dissipation rating of 0.85 watts, making it suitable for low-power applications. It is uses a heavily doped p-type material as the zone layer, giving it a wide breakdown voltage window. This makes it suitable for regulating voltage and providing protection against transients.

The PTV5.6B-E3/85A diode is designed to handle up to 0.85 amperes of current and has an excellent temperature coefficient. It also has highs resistsAnce and good stability, making it an ideal choice for regulating and protecting circuits from thermal variations.

The PTV5.6B-E3/85A diode is used in a variety of applications, including voltage regulation, over voltage protection, and surge protection. It is also used as a replacement for an over-voltage relay in automotive applications. Due to its low power dissipation and wide voltage window, it is also suitable for use in phones, computers, and other electronic devices.

The working principle of the PTV5.6B-E3/85A diode is based on a Zener breakdown effect, which occurs when a voltage exceeding the devices breakdown voltage is applied across its terminals. This effect results in the depletion layer growing in width, reducing the potential barrier between the terminals.

When this voltage is applied, the current starts to flow, allowing it to act as a resistor and regulate the voltage. As the voltage across the diode increases, the current flowing through it increases, causing the voltage across the diode to remain constant. This effect makes the PTV5.6B-E3/85A diode ideal for use in voltage regulation and over voltage protection.

The PTV5.6B-E3/85A diode also has a high reverse breakdown voltage, which makes it suitable for use in surge protection applications. In such applications, the diode acts as a reverse bias resistor and limits the current flowing through it.

The excellent temperature coefficient of the PTV5.6B-E3/85A diode makes it suitable for use in temperature sensitive applications, such as temperature control circuits, timers, and temperature sensors. It also has a low forward voltage drop, making it suitable for use in regulated power supplies.

In conclusion, the PTV5.6B-E3/85A diode is a single Zener diode with a breakdown voltage of 5.6 volts and a low dissipation rating of 0.85 watts. It has a wide breakdown voltage window and a high reverse breakdown voltage, making it suitable for use in voltage regulation and over voltage protection applications. It has an excellent temperature coefficient, making it suitable for use in temperature sensitive applications, and a low forward voltage drop, making it suitable for use in regulated power supplies.
