Why Is the B58944 Datasheet Hard to Find?

NEC discontinued many legacy components after the Renesas merger. Consequently, older part numbers like the B58944 are often: NEC B58944 is a specialized automotive integrated circuit

• High-speed switching: The NEC B58944 has a fast switching speed, which enables efficient operation in high-frequency applications.
• Low on-resistance: The component has a low on-resistance (RDS(on)) of 44mΩ, which minimizes power losses and heat generation.
• High drain-source voltage: The NEC B58944 can withstand high drain-source voltages (VDSS) of up to 60V, making it suitable for a wide range of applications.
• Low gate-source voltage: The component has a low gate-source voltage (VGS) of ±20V, which ensures reliable operation and reduces the risk of damage.
