Datasheet for the 2SD1776 transistor, which the 2SD prefix marks as an NPN bipolar device for low-frequency applications. The 59 KB PDF should present maximum ratings, DC current gain, saturation voltages and outline dimensions. Technicians use it to confirm the pin order before reinstalling a part, to test junctions with a diode-check meter, and to cross-reference a replacement whose voltage, current and power dissipation are at least equal to those of the original component.
