- Toshiba introduced three new 40V N-channel MOSFETs for automotive power applications.
- The new package design improves current capacity, efficiency, and thermal performance.
Toshiba Electronics Europe GmbH has announced the launch of three new 40V N-channel power MOSFETs, namely XPMR5904PB, XPMR7404PB, and XPMR8504PB. Introduced on June 4, the devices are engineered for a range of automotive applications including inverters, semiconductor relays, load switches, and motor drive systems. The new additions are intended to support growing demand for efficient power management solutions in modern vehicle electronics while maintaining strong electrical and thermal performance characteristics.
Key Features of the New MOSFET Portfolio
Among the newly launched devices, the XPMR5904PB incorporates Toshiba’s latest SOP Advance(EWF) package technology. The package utilizes a copper clip structure to connect the semiconductor chip and leads, helping reduce electrical resistance and improve current flow throughout the device. The enhanced structure also expands the chip mounting area, contributing to improved heat dissipation and operational stability under demanding automotive conditions. These design enhancements allow the device to achieve a drain current rating of up to 180A.
Performance Improvements Delivered by SOP Advance(EWF)
The updated package architecture provides measurable improvements compared to earlier package designs. Toshiba states that the XPMR5904PB delivers approximately 20% higher drain current capability than comparable devices using the previous package generation. In addition, the MOSFET achieves a 25% reduction in on-resistance (RDS(ON)) and a 38% reduction in thermal impedance. These improvements help minimize power losses, enhance energy efficiency, and support more reliable operation in automotive power control applications.
Performance Comparison of XPMR5904PB
| Parameter | Improvement |
|---|---|
| Drain Current Capability | Up to 180A (Approximately 20% Higher) |
| On-Resistance (RDS(ON)) | 25% Lower |
| Thermal Impedance | 38% Lower |
The launch expands Toshiba’s automotive semiconductor portfolio and targets applications where efficient switching performance, thermal management, and high current handling are critical. By combining advanced packaging technology with lower electrical losses, the new MOSFET family is designed to support next-generation automotive electronic systems requiring higher efficiency and improved power density.
