Introduction

The SBL1640CT-E3/45 is a rectifier diode array from Vishay, a highly recognized semiconductor manufacturer. The device is designed for general-purpose rectification in high efficiency SMPS systems. It allows for low forward voltage drop, capable of up to 280V surge protection, and high current capability.

Application

The SBL1640CT-E3/45 is mainly used in the power supply systems, switching and linear regulators, telecommunication systems, and other consumer electronics. In these systems, the SBL1640CT-E3/45 is primarily used as an ESD protection device to protect sensitive components from high levels of electrostatic discharge (ESD). The device is also capable of protecting other connected circuits and components, such as inductors, transistors, and semiconductor packages.

The SBL1640CT-E3/45 can also be used in automotive applications, such as the starter and alternator systems, EV applications, and other power control circuits. Applications where the SBL1640CT-E3/45 is employed are typically temperature critical, meaning the components need to operate even in extreme temperatures or environments. The SBL1640CT-E3/45 is able to operate up to 175C, ensuring that the system’s components are safe from over-heating and other related damages.

Working Principle

The SBL1640CT-E3/45 has four dual Schottky rectifier pairs and differs from the traditional Schottky rectifiers in several ways. The most notable difference is that the SBL1640CT-E3/45 has two back-to-back (opposite polarity) rectifiers rather than a single rectifier. This two-channel design makes the SBL1640CT-E3/45 unique, as it allows the device to provide both directions of current to the load.

The SBL1640CT-E3/45 also has an optimized diode design characteristic. The cathode-type diodes of the SBL1640CT-E3/45 have improved current handling capacities and have low forward voltage drops which help reduce power dissipation and provide better performance. The anode-type diodes have optimized guardband protection that helps protect the external components from damage due to electrostatic discharge.

In addition to the two-channel design and optimized diode characteristics, the SBL1640CT-E3/45 also features a wide operating temperature range. This temperature range makes the SBL1640CT-E3/45 well suited for commercial and automotive applications. The device also features high forward surge capability, low leakage current, and over-voltage protection.
