STB4045CTR

The STB4045CTR is a rectifier array device produced by STMicroelectronics. It is a low-voltage, high-current diode array that is used in bridge rectifier and freewheeling application. The device consists of four individual diodes connected in an inverse parallel configuration with a center tap point. Each diode in the array has a peak repetitive reverse voltage of 40V and a peak forward current rating of 45A.

The STB4045CTR rectifier array is primarily used in bridge rectifier, freewheeling, flyback and bidirectional boost converter applications. It is also suitable for AC-DC rectification and power factor correction circuits. The device offers several advantages over conventional single diode rectifiers, such as improved EMI, surge performance and thermal performance. The STB4045CTR is also offered in both surface mount and through-hole packages.

In bridge rectifier applications, the STB4045CTR rectifier array is used to convert AC power inputs into DC power outputs. The device is connected across the two input terminals, with each diode in the array placed in series between the two inputs. When an AC voltage is applied to the input terminals, the diode array acts as a four-way barrier, allowing current to flow in one direction and blocking current in the opposite direction. This rectifies the AC voltage input into a DC voltage output. The advantage of using the STB4045CTR rectifier array in bridge rectifier applications is that it provides better EMI and surge performance than conventional single diode rectifiers.

In freewheeling applications, the STB4045CTR rectifier array is used to convert DC power inputs into AC power outputs. The device is connected across the two input terminals, with each diode in the array placed in parallel between the two inputs. When a DC voltage is applied to the input terminals, the diode array acts as a four-way contact, allowing current to flow in both directions. This rectifies the DC voltage input into an AC voltage output. The advantage of using the STB4045CTR rectifier array in freewheeling applications is that it provides better thermal performance than conventional single diode rectifiers.

In flyback applications, the STB4045CTR rectifier array is used to convert DC power inputs into AC power outputs. The device is connected across the two input terminals, with each diode in the array placed in series between the two inputs. When a DC voltage is applied to the input terminals, the diode array acts as a four-way switch, allowing current to flow in one direction and blocking current in the opposite direction. This rectifies the DC voltage input into an AC voltage output. The advantage of using the STB4045CTR rectifier array in flyback applications is that it provides better EMI and surge performance than conventional single diode rectifiers.

In bidirectional boost converter applications, the STB4045CTR rectifier array is used to convert AC power inputs into DC power outputs. The device is connected across the two input terminals, with each diode in the array placed in parallel between the two inputs. When an AC voltage is applied to the input terminals, the diode array acts as a four-way contact, allowing current to flow in both directions. This rectifies the AC voltage input into a DC voltage output. The advantage of using the STB4045CTR rectifier array in bidirectional boost converter applications is that it provides improved EMI, surge performance and thermal performance compared to single diode rectifiers.

The STB4045CTR rectifier array is a versatile device that is suitable for a variety of power conversion and rectification applications. The device offers several advantages over conventional single diode rectifiers, such as improved EMI, surge performance and thermal performance. In addition, the device is offered in both surface mount and through-hole packages, making it suitable for a wide range of applications.
