Introduction

The SBR1045CTL-13 is a silicon-based rectifier array with a built-in transient-voltage suppression (TVS) circuit. Its purpose is to provide reliable, low-zero-voltage (LZV)-precision, reverse-bias surface mount protection in high-voltage and/or high-current applications. It has a reverse-biased connection across the sense element, providing a known voltage that, when exceeded, results in the shorting of the signal path, whereupon the SBR1045CTL-13 can block over-voltage transients associated with inductive load-switching, with excellent immunity against electrostatic discharge (ESD).

What is a Silicon-Based Rectifier Array?

A silicon-based rectifier array is a type of semiconductor device commonly used to build high-precision rectifiers. It is composed of several silicon-based rectifier components connected in series, as opposed to a single rectifier unit.The main advantage of using a silicon-based rectifier array is that it allows for highly precise rectifier designs, which can be made to minimize voltage drop, reduce noise, and reduce the amount of power wasted due to heat. They also provide superior reliability and durability when compared to other types of rectifier designs.

How Does SBR1045CTL-13 Work?

The SBR1045CTL-13 is a three-application surface mount package. It includes an integrated diode array which consists of three series-connected rectifier units; these are connected in parallel with a reverse-biased internal sense element. In operation, the sense element is pre-biased to a given voltage, Vt, and when the supply voltage exceeds Vt, current will flow through the diode array, allowing the circuit to provide over-voltage protection for the protection circuit underlying it. This action effectively shorts the signal path, blocking any over-voltage transients associated with inductive load-switching.The SBR1045CTL-13 is also designed with high surge capability, as well as excellent ESD immunity. This makes it an ideal solution for both high-voltage and high-current applications which require precise, reliable, and durable reverse-biased protection.

Applications of the SBR1045CTL-13

The SBR1045CTL-13 is particularly well-suited for applications such as: switch-mode power supplies (SMPS) for AC/DC converters, diode driver circuits, inductive load drivers, motor drivers, and any other application requiring reverse-biased protection circuit.For example, the SBR1045CTL-13 could be used to provide over-voltage protection for a motor driver circuit. This would provide very reliable protection from transients associated with inductive load-switching, as well as very high surge capability and excellent electrostatic discharge (ESD) immunity.The SBR1045CTL-13 is also particularly well-suited for high-precision diode applications where precise voltage and current control is required. This is due to its low-zero-voltage (LZV)-precision characteristic; which ensures that current will flow through the diode array at a very precise voltage level — even under adverse environmental conditions.

Conclusion

The SBR1045CTL-13 is a versatile and reliable silicon-based rectifier array with a built-in transient-voltage suppression (TVS) circuit. It is ideal for applications where precise, low-power, reverse-biased protection is required — such as inductive load-switching, switch-mode power supplies (SMPS) for AC/DC converters, diode driver circuits, and motor drivers. Additionally, its low-zero-voltage (LZV)-precision characteristic makes it particularly well-suited for high-precision diode applications.
