CN4157 BK

Introduction

The CN4157BK is a single rectifier diode designed for power applications. It consists of two diodes connected in parallel with each other, producing a single unidirectional voltage drop in forward direction. This diode is suitable for use in high power, low voltage applications such as AC-to-DC power supplies, converters, switchmode power supplies and power management systems.

Features

The CN4157BK has the following features:

• High voltage ratings (up to 1000V)
• Low forward voltage drop (VF 0.5V)
• High surge capability (up to 120A)
• Low reverse leakage current (IR 0.25µA)
• High temperature capability (up to 150°C)

Application Field and Working Principle

The CN4157BK is ideal for use in power supplies, converters, and power management systems. The device can be used to provide efficient power transfer and protection from current surges and reverse voltage.The two diodes connected in parallel allow the diode to provide voltage drop in one direction only. As a result, current only flows in the forward direction, allowing the device to act as a rectifier. The device also features a low forward voltage drop (VF 0.5V) and low reverse leakage current (IR 0.25µA) which helps to reduce the power losses in the circuit. In addition, the high surge capability and operational temperature range ensures reliable operation even in harsh operating conditions.The CN4157BK can also be used in automotive applications. As a result of its high breakdown voltage and high temperature range, the diode can be used for battery isolation, protection from spikes and reverse polarity protection.

Conclusion

The CN4157BK is a single rectifier diode designed for power applications. It consists of two diodes connected in parallel, producing a single unidirectional voltage drop in the forward direction, thereby acting as a rectifier. The device is suitable for use in high power, low voltage applications such as AC-to-DC power supplies, converters, switchmode power supplies, power management systems and automotive applications.
