Introduction

MOSFETs are common discrete devices primarily used to convert changes in input voltage into changes in output current. They can be classified into two types based on substrate doping: N-channel and P-channel. By controlling the voltage on the gate, they regulate the current between the source and drain, thus enabling switching functionality.

In this edition, VBsemi introduces a recently launched N-channel MOSFET product, the VBL7601, suitable for motor drive circuits, chargers, and other circuits. This product adopts advanced chip mounting technology, significantly improving the thermal performance of the package.

This packaging design is well-suited for applications requiring high power and efficiency in compact system sizes. Examples include automotive DC-DC converters, automotive air compressor controls, photovoltaic inverters, motor drives, UPS power supplies, and switch-mode power supplies.

Product Features

The VBL7601 from VBsemi is an N-channel MOSFET with excellent performance characteristics and operation principles. Specifically, when a positive voltage is applied to the gate, a conductive channel forms, connecting the source and drain, enabling conduction. Conversely, when a negative voltage is applied to the gate, no conductive path is formed, resulting in cutoff.

The VBL7601 has low on-resistance, fast switching speed, and high load current capability.

Referencing the specifications in the datasheet below: drain-source voltage is 30V, gate-source voltage is ±20V, drain current is 200A, on-resistance is 0.002, and other parameters are referenced accordingly.

Package Performance

The VBL7601 utilizes the TO-263-7L package, a surface-mount package form utilizing advanced encapsulation technology. Compared to traditional through-hole packages, it is more compact in size and offers great convenience during surface-mount soldering processes.

This package features multiple pins, which are connected to the source (S) in parallel, significantly reducing the package impedance. Consequently, in high-current operating environments, it effectively reduces conduction losses and enhances the overall circuit performance.

Product Applications

With its outstanding electrical performance, the VBL7601 exhibits stability, reliability, and low power consumption, making it an ideal choice for many customers.

The VBL7601 performs excellently in various circuit applications, including drive, switch, amplification, regulation, filtering, protection, and charging. Its applications are extensive, including chargers, adapters, inverters, power supplies, power tools, electronic cigarettes, optocouplers, small household appliances, energy storage devices, smart water meters, routers, set-top boxes, and automotive electronic products.
