Diodes - Rectifiers - Arrays

The VB30100C-M3/4W is an advanced rectifier array from Vishay that provides an improved product solution for power supply, high efficiency and much smaller package size. This diode array features PN4A type forward current rating of 3.0 Amps, reverse voltage range of 100 Volts, and four way common source.

Application Field

VB30100C-M3/4W is ideal for applications with directcurrent powering, frequency rectification, PC power supplies, and fly/boost converters. Since its compact size and low profile allowing easy placement, it is wellsuited for densely packed power supply design. Moreover, its high surge current capability is valued for battery charger and telecom applications.

Working Principle

A diode is a two-terminal electronic component that functions as an electrical switch or rectifier. It is basically an electron valve, because it can pass current in one direction (forward biasing) but block it from flowing in the opposite direction (reverse biasing). As a rectifier, it will allow current to flow in one direction only, and hence can be used to convert alternating current (AC) to direct current (DC).

In case of VB30100C-M3/4W, it has four diodes sharing a common source. It utilizes the combined forward current flowing through the 4 diodes with the same polarity, thus forming a more efficient rectifier array. Also, due to its higher reliability, the device provides an improved Ac/DC solution.

Advantages

• Higher forward current and forward voltage ratings
• Low thermal impedance for improved power dissipation
• Low reverse recovery time for improved current ripple issues
• Environmentally friendly, RoHS compliant design

The VB30100C-M3/4W rectifier arrays from Vishay are thus ideal for power supplies, high efficiency, and small package size applications. These rectification products are designed for reliable and high volume production due to their superior electrical and thermal performance.

Conclusion

VB30100C-M3/4W rectifier arrays are reliable and costeffective solutions for high performance, small package size and high efficiency applications with direct current powering, frequency rectification, PC power supplies, and fly/boost converters. It provides improved Ac/DC solutions with low thermal impedance and heat dissipation requirements. Additionally, it is RoHS compliant and offers environment friendly attributes.
