DST2080C Application Field and Working Principle

The DST2080C is a rectifier array designed and developed by Diodes Incorporated. As a specialized type of rectifier, this device is designed to convert AC line voltage into DC voltage. This is accomplished by the DST2080C’s use of a pair of Schottky rectifiers. This diode array works in both directions, so that it can be used to filter out any AC voltage that might be present in a DC output. It is also capable of providing reverse blocking and current limiting.

Types of Applications

The DST2080C is often used in low-voltage DC power supply applications, such as 12V and 24V DC applications. It is often used in input voltage rectification in products such as uninterruptible power supplies (UPSs) and vehicles. It is also used in drives and motor controls that require a DC-to-AC conversion.

Features of DST2080C

This device is a low-profile, space-saving component that is usually assembled in a 6-pin DIP (dual-in-line) package. Diodes Incorporated has designed the DST2080C to have a low forward voltage drop, with an operating temperature ranging from -55°C to 150°C. The device has a peak repetitive forward current of 200A and a reverse DC current of 10µA at 25°C.

Working Principle of DST2080C

The DST2080C has two Schottky rectifiers connected in series. When the rectifier is exposed to an AC voltage, the rectification process is activated by the precisely tuned diode characteristics of the Schottky diodes. This allows the appliance to discard half of the AC waveform, limiting the output to the positive or negative half cycle, thus providing the DC voltage.

Each rectifier is connected to the power supply’s positive and negative voltage terminals. When an AC voltage is applied to the device, one diode’s anode is attracted to the positive voltage, closing the circuit. The other diode’s anode is attracted to the negative voltage, thus closing the circuit in the other direction. As currents flow through each diode, the device limits the voltages, letting only the half that corresponds to the device’s thresholds to pass through.

The DST2080C is designed to provide protection against surge and transient voltages. The device also provides reverse blocking and current limiting, which prevents damage to the appliance’s components. Additionally, the device’s low-profile design and dual-in-line package make it an ideal choice for applications in which a rectifier needs to be connected between two electronic components.

Conclusion

The DST2080C is a rectifier array manufactured by Diodes Incorporated, designed for low-voltage DC power supply applications. The device utilizes two Schottky rectifiers to convert AC line voltage into DC voltage and is capable of providing reverse blocking and current limiting. Additionally, the DST2080C’s low-profile design and dual-in-line package make it the ideal choice for many applications in which a rectifier needs to be connected between two electronic components.
