The SBR1U30CSP-7 is part of the diodes-rectifiers-single family, under the STMicroelectronics brand specifically. The diode is specifically designed to operate in the 500V range, with a maximum forward current of 1A. The diode has a unique case style of “DO-214AC”, a plastic body case and a type “TNY-PbF” of terminal finish.

The diode is an ideal solution for reverse voltage protection application, thanks to its high-reliability ratings given by its regulatory body - UL, INMETRO and TUV certifications. The diode is also compliant with the RoHS directives, meaning it will not contain more than 0.1% of substances such as lead, hexavalent chromium, mercury, and certain flame retardants. This makes it suitable for use in consumer electronics, automotive, industrial, and medical devices.

SBR1U30CSP-7 features a Fast Reverse Recovery Time of 80ns, enabling the diode to operate with a high-frequency ac power source. It also contains an rd(on) of 4.5Ω and an isolation voltage of 4350Vrms, which provides the necessary protection when used with power sources or AC power lines. In addition, the diode is capable of handling up to 1.2mA of Reverse Leakage current, making it suitable to protect sensitive components in higher-power applications.

The working principle of the SBR1U30CSP-7 lies in its rectifying capabilities. The diode works by allowing current to flow in only one direction. When the forward current is applied, it allows electrons to flow through its P-type body, into the N-type body. This process creates an electron “depletion region” at the interface of the two layers, which can act as a barrier for current flowing in the opposite direction. This results in the device operating as a rectifier, allowing current to only flow in one direction.

The SBR1U30CSP-7 is used in a variety of applications, such as AC/DC power supplies, consumer electronics, automotive, industrial, and medical. In AC/DC power supplies, the diode is commonly employed as a rectifier, converting the incoming AC voltage to DC voltage. In consumer electronics, the diode is used as a protection device against reverse working voltages or to protect sensitive components in higher power applications. Automotive, industrial, and medical applications often use the device as a bridge rectifier to convert incoming AC power into DC power.

The SBR1U30CSP-7 diode is a testament of STMicroelectronics’ commitment in providing excellent quality components which meet the wide-range of applications’s requirements. With its unique case style and impressive ratings, the device is ideal for an array of power applications and serves as the perfect choice for any engineer.
