小型MOSFET可降低电池供电设备的功耗并延长其工作时间

Product News 2024-10

The package photograph of small MOSFETs bring lower power consumption and longer operating times to battery-driven devices.

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched small MOSFETs featuring low gate leakage current and low drain cut-off current for portable equipment and IoT devices such as wearable devices and tablet devices.

The new products have significantly reduced the drain cut-off current to 60nA (max)[1] compared with 1μA (max)[2] of Toshiba existing MOSFET products and guarantee a gate leakage current of 50nA (max) under gate-voltage conditions when the MOSFETs are in the on state (at VGS=5V)[2]. These characteristics are suitable for applications that require to minimize total energy increased by high-density design of semiconductor devices and for battery-powered portable devices. They significantly help energy saving and battery longevity of the equipment.

The new products are 29 types of 6 series: 4 series of 30V and 20V N-channel MOSFETs and 2 series of -20V P-channel MOSFETs. A variety of small surface mount packages are available to meet the diverse needs of our customers.
