Diodes - Rectifiers - Arrays are used in circuit designs that require electric current to flow in one direction only. The 689-3P is a common type of diode; it is also a modular array. This device offers additional advantages over single diode rectifying devices, mainly due to its ability to handle larger currents and voltages with greater efficiency.

The 689-3P is a reverse blocking tri-level diode array connected in common cathode configuration. It offers a number of benefits compared to single component rectifiers. Its construction is such that each of its three serially connected diodes is connected in parallel with the other two, allowing larger currents and voltages to be handled simultaneously. The three smaller diodes reduce voltages and current-limiting resistors are used to limit the peak inverse voltage of each diode.

In addition to its reverse blocking capabilities, the 689-3P offers superior noise immunity, a narrower voltage drop and a faster reverse recovery time compared to single component rectifiers. This is because the multiple levels of diodes allow more efficient switching of the larger voltages and current values. With faster reverse recovery time, it is possible to reduce the power dissipation of a rectifier.

The 689-3P application field includes power supplies, DC-DC converters and AC/DC converters. It is also used in automotive applications, such as fuel injectors, power windows, door locks and AC/DC converters. Its superior current handling capability and fast switching time make it suitable for many applications where efficiency and reliability are important.

The working principle of the 689-3P is fairly simple. When the voltage across the diode array is greater than the peak inverse voltage (PIV) of the individual diodes, current will pass through the device in a forward-biased direction. In this situation, the voltage applied to the device is reduced as it passes through the reverse blocking diode.

However, if the voltage applied to the device is less than the PIV, the current flowing through the diode array will be blocked in the reverse direction. This blocking action allows the device to act like a switch and prevents the passage of unwanted electric current. The device also works well in controlling AC or DC power supplies or other circuits with varying demands.

The 689-3P has become the industry standard for reverse blocking diode arrays and has proven its reliability in a broad range of applications. Its efficient multi-level design allows for a wider range of current and voltage handling capabilities and its fast switching times make it suitable for a wide range of requirements. The 689-3P is a robust and reliable device that is frequently used in precision circuitry and power systems around the world.
