Diodes – Rectifiers – Arrays are key components in the design of power supplies, voltage regulation and DC-DC conversion. The DSEC59-06BC is a specific type of array and it offers a wide range of application possibilities across multiple industries. The following article provides an overview of its application fields and working principle.

DSEC59-06BC Application Fields

The DSEC59-06BC is a single-phase, surface mount, isolated synchronous rectifier array used for connecting to direct current (DC) power supplies. The typical application field for such an array is the computer industry. It is used in the manufacturing and assembly of motherboards, as well on computer peripherals and power modules. In addition, it may be applied to motor drives and LED lighting.

In the automotive context, the DSEC59-06BC may be used in the production of cars, buses and trucks. It can be deployed when the vehicle requires improved power efficiency and higher power density. Additionally, it is applicable to inverters and battery management systems. It could also be used in 4WD vehicles, hybrid systems and battery chargers.

The array is also suitable for applications in the telecom and industrial sectors. In telecom, it can be employed to construct high-efficiency power supplies, such as module boards, switches, routers and media converters. In the industrial domain, it has been successfully deployed in solar inverters, generators, uninterruptable power supply (UPS), welding machines, variable speed drives and various safety circuits.

DSEC59-06BC Working Principle

At a high level, the array is comprised of four isolated ‘low-side’ synchronous rectifiers, which use current sensing MOSFETs. In normal operation, the internal control logic of the array creates gate bias voltages, which turn on the power MOSFETs. As a result, the negative DC supply voltage is connected to the circuit, allowing power to enter the system. A broad array of protections is also in place to protect the device from possible failures.

The DSEC59-06BC operates within a wide supply voltage range, from 6V up to 75V. It is available in a SOP-8 package, and its power dissipation is low, usually coming in at less than 1 Watt. The operating temperature range is -40ºC to +125ºC and a wide range of additional specifications are available, depending on the chosen model.

In conclusion, the DSEC59-06BC is a high-performance synchronous rectifier array, with applications spanning multiple industries. Its flexibility, working principles and technical characteristics, make it an attractive choice for designers and engineers when working on power conversion and DC-DC conversion projects.
