Toshiba launches new 12V common-drain N-channel MOSFET to help protect mobile device batteries

News on May 18th, Toshiba Electronic Components and Storage Co., Ltd. (hereinafter referred to as "Toshiba") announced today the launch of a new electronic device called "SSM14N956L". This device is a 12V common-drain N-channel MOSFET with a rated current of 20A. It is mainly used in battery protection circuits for lithium-ion battery packs in mobile devices. The product is available for volume shipping starting today.

Highly stable protection circuits must be used to improve the safety of lithium-ion battery packs. These circuits require characteristics of low power consumption and high-density packaging, demanding MOSFETs to be compact and thin with even lower drain-source on-resistance..

SSM14N956L uses the same technology as the previously released SSM10N954L, both of which use Toshiba’s own patented micro-machining process. The device achieves low power consumption through industry-leading low on-resistance characteristics and reduces standby power consumption through industry-leading low gate-source leakage current characteristics. These features help extend battery life. In addition, the new product also uses a new small and thin package called TCSPED-302701 (dimensions are 2.74mm × 3.0mm, thickness is approximately 0.085mm).

According to ITBEAR Technology Information, Toshiba’s new electronic device SSM14N956L will provide a more reliable and efficient solution for the protection circuit of lithium-ion battery packs in mobile devices. Low power consumption and high-density packaging reduce the heat generated by the battery pack during charging and discharging, thereby further improving the safety performance of the battery pack. This product not only reaches industry-leading levels in terms of on-resistance and standby power consumption, but also brings more flexibility to the design of mobile devices. User demands for long battery life and safety will be met as Toshiba's technological innovations will further promote the development of mobile device battery technology.
