Transistors - Bipolar (BJT) - Arrays

PBSS4350SS,115 is a voltage-controlled, N-channel MOSFET array integrating four N-channel devices for high current switch-mode operation. It is designed for applications requiring high-side switching, where load currents up to 1.8A can be supported. It offers wide bandwidth control capabilities, improved thermal performance, and more efficient current control than single-device solutions.

Application Field

The main applications of the PBSS4350SS,115 are power switching, load current-control, and voltage-level directing in automotive and non-automotive markets. It is commonly used in systems that require higher switch-mode performance such as bus converters and DC-DC converters. It is particularly suited for high power applications in board-level power management, medical (particularly portable medical) and industrial markets. Some of its applications are:

• DC-DC converters
• Bus converters
• Board level power management
• Portable medical applications
• Industrial applications

Working Principle

The PBSS4350SS,115 consists of four N-channel MOSFETs in an Array. It is a four-way power switching device with wide-bandwidth control capability. The circuit operates by controlling the gate voltage of all four devices, which allows current to flow between the sources and the drains. With the propagation delay time, which is the time taken for an input signal to be transferred to a full output signal, which is very low compared to other devices, this device acts as a high-speed switch. The maximum power dissipation of 2 W and the maximum current handling of 1.8 A makes this IC suitable for applications requiring high current and very fast response.

Conclusion

The PBSS4350SS,115 is a efficient array of N-channel MOSFETs, which offers wide-bandwidth control and high circuit speed, making it suitable for power switching and voltage operations. The good thermal properties and high current capability make it suitable for high-power applications in medical and industrial markets.
