PTV5.1B-E3/85A

The PTV5.1B-E3/85A diode is one of the many single Zener diodes available on the market, and is applicable to a wide range of applications. Zener diodes are widely used in many applications such as voltage regulation, voltage clamping, and as a switch in a circuit.

The PTV5.1B-E3/85A is a single Zener diode with a maximum power rating of 5 Watts and a reverse bias voltage of 5.1 Volts (V). It’s breakdown voltage over temperature range is 4.7V and 6.4V at 25°C and 0°C respectively. It’s Zener voltage range is 4.6 - 5.6V for E3/85A, and the nominal capacitance at 75V is 17pF. It also has a forward current rating of 20mA, and an average rectified forward current rating of 70mA.

The working principle of a single Zener diode is based on the fact that the breakdown voltage of a diode is predictable and repeatable, and when this voltage is exceeded by the applied voltage, the diode will break down, allowing current to flow in the reverse direction. This current, however, is limited to a specific value, known as the Zener or breakdown current.

The PTV5.1B-E3/85A is primarily used in applications such as voltage regulation, voltage clamping, and as a switch in a circuit. It can be used in low voltage power supplies, voltage regulators and voltage protection circuits where current limiting and the protection of sensitive components is required. It can also be used in many electronic applications such as audio circuits, computer circuits, and other electronic devices that require a steady and reliable voltage source.

The PTV5.1B-E3/85A is a reliable, cost-effective solution for a wide variety of applications. Its simple, predictable breakdown voltage makes it extremely useful in many circuits, as it eliminates the need for precision voltage adjustment and accuracy. The diode is also robust and can withstand large amounts of heat, ensuring it operates reliably for many years in many different environments.
