1N4004 is a diode of the Rectifiers family, and in particular, falls under the Single-type rectifiers. It is a four-layer semiconductor, constructed in the shape of a symmetrical bridge, with a slightly asymmetrical bridge rectification output. This makes it suitable for applications such as bridge rectification,capacitor charging, forward and reverse parallel rectification, and other applications such as voltage and voltage-regulator circuits. 1N4004 has a high voltage performance of 400 volts, and a surge current rating of 30A.

This 1N4004SP TR-RPCU is a special type of diode with a rectified maximum limiting voltage of 400V and a forward current of 30A. It is mainly used for bridge rectification, capacitor charging, and reverse parallel rectification. This diode can be used as a polarity protection, overvoltage stabilisation, DC filter, voltage regulator and many more. As such, it is a very versatile and reliable device, capable of achieving the desired performance even in harsh environments.

Before delving into the working principle of this diode, it should be noted that it is a reverse polarity-powered circuit whose circuit efficiency is improved by a pulsed current. The 1N4004 is used mainly in bridge rectification, consisting of four rectifying diode elements connected in a symmetrical bridge manner. It works in tandem with an AC/DC power source to convert line voltage AC to a stable DC voltage.

This diode is composed of two P-type and two N-type semiconductor layers. The P-type layer works as the cathode, providing the positive direction for current flow, and the N-type layer works as the anode, providing the negative current flow. When the voltage is applied, the P-side will be at a ratio of 1.4 times the input differential voltage, making the reverse polarity protection even stronger. Moreover, the reverse breakdown voltage of this diode is limited to 400V.

The working principle of 1N4004SP TR-RPCU is simple: when a forward voltage is applied between the two terminals, current flows from P-type layer via N-type layer to the other terminal. On the other hand, if the voltage is reversed, the current flow will be blocked by the P-type layer and the N-type layer, which makes the diode a polarity protector. When the overlapping current layers of the diode interact, the effective voltage is limited to 400V, thus providing the protection.

The 1N4004SP TR-RPCU is a highly efficient and reliable device, with a maximum forward current rating of 30A. Its four-layer construction allows for low noise, fast switching, and long-term reliability. It has a high reverse breakdown voltage of 400V, making it ideal for applications involving high voltage AC/DC sources. Moreover, its reverse polarity protection ensures that any unexpected transient or reverse input voltage will not trigger the diode. Taking all these features into consideration, 1N4004SP TR-RPCU is an excellent choice for many different applications, both in industrial and consumer applications.
