MMBD1405 Discrete Semiconductor Products

Diodes - Rectifiers - Arrays

MMBD1405 is a popular rectifier array, which is widely used in many applications. It is a four pin, surface mount device, particularly featuring a low forward voltage of only 0.4V (max) and a high current capability of 1.0A (max). The package of MMBD1405 is made up of ceramic and is suitable for high temperature, high frequency applications.

Applications

MMBD1405 containing four diodes is capable of providing four separate and independent rectifying functions. It can be deployed in many different applications such as stock switchers, power adapters and battery charging circuits. It is also used in high temperature and high current rectification purposes. Besides, it can be used as a general purpose rectifying element with different polarity.

Working Principle

MMBD1405 rectifier is a specialized semiconductor device which converts alternating current (AC) into direct current (DC). It works by allowing current to flow in one direction only and blocking it in the opposite direction. When the voltage on the MMBD1405 is forward biased, electrons pass through the junction, arriving at the anode and providing a low forward voltage of 0.4V (max). However, when the voltage is reversed, the device is disabled and no current can pass through. The MMBD1405 can be used as a switch to allow current to pass through the circuit.

Conclusion

MMBD1405 is a highly versatile and efficient rectifier array, suitable for many applications involving rectification of AC to DC with low forward voltage, high current capability and high temperature operation. It can be employed as a general purpose rectifier or for more specific applications like stock switchers and battery charging circuits to provide great reliability and efficiency.
