Introduction

VS-VSKC71/14 is a type of diode array. It\'s an integrated offering from Vishay that contains two ultrafast rectifier diodes in the same package. This product offers the ability to reduce size while having good performance, making it a popular choice for applications like power supplies, battery chargers, and adapters.

Applications

VS-VSKC71/14 is most commonly used in switch-mode power supplies, chargers, and adapters due to its good low-noise performance, low voltage drop and fast reverse-recovery, translating to high efficiency. Also, VS-VSKC71/14 diodes can find use in power-factor-correction, snubber circuits, and other current-protection applications. This wider range of benefits makes VS-VSKC71/14 diode array a popular choice for designers and engineers that need a complete package.

Working Principle

The VS-VSKC71/14 diode array provides low voltage drop and fast recovery time, allowing for greater efficiency and lower power consumption. This array also combines two ultra-fast rectifier diodes in a package. The operating principle for both rectifier diodes is similar; each diode has two electrodes with an anode on one end and a cathode on the other. The anode is the positive electrode and accepts the current, while the cathode is the negative electrode, which will reject the current.

When the anode of the diode array is higher than the cathode, or forward biased, the current will be allowed to flow into the anode and out of the cathode due to the depletion layer formed. When the cathode is higher than the anode (reverse bias), the depletion layer will act like an insulator, preventing the flow of current. This is known as the forward and reverse voltage blocking capability, respectively.

The VS-VSKC71/14 diode array is an ideal choice for higher-current applications due to its low resistance and the two ultra-fast diodes that combine to form a package. Moreover, its higher forward voltage drop and ultra-fast reverse-recovery time make it an optimal solution for power supplies, battery chargers, and adapters, among other applications.

Conclusion

In conclusion, the VS-VSKC71/14 diode array provides good performance, a low resistance and it offers the ability to reduce size, making it a popular option in switch-mode power supplies and adapters, as well as in current-protection applications. It also has a higher forward voltage drop and ultra-fast reverse-recovery time, which adds to its benefits as an integrated diode array solution.
