Nec B58944 Datasheet 2021

NEC B58944 (often associated with the part number D43256BGU-70Y

High current gain: The NEC B58944 has a high current gain (hfe) of 200-400, making it suitable for applications that require high current amplification.
Low saturation voltage: The device has a low saturation voltage (VCE(sat)) of 0.2V, which ensures efficient operation and minimal power loss.
High voltage rating: The NEC B58944 has a high collector-emitter voltage rating (VCEO) of 80V, making it suitable for use in applications that require high voltage handling.
Low noise figure: The device has a low noise figure (NF) of 2dB, making it suitable for use in low-noise amplifier applications.

Viewing angle: The emission half-angle (e.g., 120° typical) informs optical coupling and perceived brightness for indicators or backlights.

It is frequently replaced during ECU board repairs when the unit fails to communicate or drive engine components properly. High-Side Driving:
