The SBR40U300CT is a rectifier diode array from STMicroelectronics. It is a surface mount 40V/300A device that provides superior ESD protection suitable for power management in harsh environment applications. The device is a plastic encapsulated package, with a lead frame construction, and is a RoHS Compliant product. It is designed to be used in switch mode power supply applications, telecoms, networking and industrial control systems.

The SBR40U300CT has high blocking capability, allowing a low stand-off voltage of 40V and low forward voltage drop of 1.1V @ 20-25A of reverse leakage current at 25°C. This provides excellent current handling ability and superior ESD protection. The high surge current performance, up to 300A, gives superior protection against electrical surges.

The SBR40U300CT includes a hermetically sealed mold which makes it suitable for a wide temperature range of -55 to +150 °C. It also has a high thermal resistance reduction compared to conventional High-Power Diodes (HPD) due to its improved thermal management of the die. This makes it suitable for high current switching applications.

The SBR40U300CT is a single 40V 300A unit with sixteen separate sub-arrays with an internal common part and common anode. Each of the sixteen sub-arrays is independently connected to its own set of external connections. An internal connection schematic is included in the datasheet that illustrates the internal connections between the parts and common terminal connections. The internal connections are designed to minimize the overall thermal profile.

The SBR40U300CT works by allowing the current to flow in one direction (the anode to the cathode), while blocking current in the opposite direction. It is a fast recovery device which ensures minimal voltage drop and high surge current handling ability. It also provides superior ESD protection and has a low on-state voltage drop, making it suitable for power management applications in harsh environment.

The SBR40U300CT is suitable for both switch mode power supply and industrial control applications. It has a low forward voltage drop of 1.1V @ 25A, making it an ideal choice for high power switch mode applications. It also has a high surge current handling capability of 300A, making it ideal for protection from electrical surges. In industrial control applications, the device’s superior ESD protection allows for reliable operation in harsh environment.

The SBR40U300CT is a forwardbiased rectifier diode array designed to provide superior ESD protection and high surge current handling capability. It is a single 40V 300A unit, with sixteen individually connected sub-arrays. Due to its low on-state voltage drop, it is suitable for power management applications in harsh environment. Furthermore, its high surge current handling capabilities allow it to be used in both switch mode power supply and industrial control applications.
