A diode array is an integrated circuit composed of multiple individually controllable semiconductor diodes connected in parallel. Used primarily in switching and rectification applications, diode arrays allow for the control of current and/or voltage flow and are composed of several p-n junctions wired in parallel. The 1PS301,115 is a dual, low-voltage, standard recovery diode array with integrated ESD protection and a wide dynamic range. It is a ceramic base package with two SCRs (Silicon Controlled Rectifier) and two diodes.

The 1PS301,115 offers excellent current capability, low forward voltage drop and low leakage current. It is designed to use a minimum of board space while providing high current capabilities and excellent thermal performance. With its ultra-high speed switching, tight tolerances, and wide dynamic range, the 1PS301,115 is an ideal choice for power management, motor control, and lighting control applications.

The 1PS301,115 is designed to provide protection when exposed to high ESD (electrostatic discharge) levels up to 5kV. In order to achieve this level of protection, the device is provided with a built-in ESD protection circuit, which includes two diodes for reverse bias protection and two SCRs for forward bias protection. This combination of components ensures a high level of protection against potential damage due to ESD.

The primary applications for components like the 1PS301,115 include power management and controlling AC mains, data and signal line protection, and general power switching. The device is also well-suited for automotive applications, power supplies, motor control circuits, and boosting or inverting applications. It can be used in AC/DC converters, DC/DC converters, power line filters, power distribution units, and various other applications where AC or DC power needs to be controlled.

The 1PS301,115 offers an adjustable input resistance of 12–30V, an adjustable gate triggering voltage of 4–14V, and an adjustable on-state current limit of 1–4A. It also features an adjustable hold current of 0.6–2A for improved reliability and prolong the life of the device. Furthermore, the device provides low on-voltage and low gate-trigger current along with a built-in short circuit protection feature.

The working principle of the 1PS301,115 diode array is based on the concept of rectification. In its most basic form, rectification is the conversion of alternating current to direct current by allowing electric current to flow in only one direction. In the case of a diode array, the multiple p-n junctions are connected in parallel such that when the input AC voltage source with a given frequency is applied to the array, only certain junctions will allow current to flow, depending on the polarity of the input AC voltage. As a result, the AC voltage is converted to a DC voltage.

In addition to rectification, the 1PS301,115 diode array provides ESD protection as well as current and voltage regulation. The ESD protection circuit prevents potential damage caused by ESD events and reduces downtime due to component failure. The device also features a wide dynamic range, meaning it can be used in applications ranging from power management to motor control circuits. Finally, its small package size, low input resistance and low gate triggering voltage make it well suited for many small to mid-sized power conversion applications.
