D718 Transistor Datasheet



This is 120V, 8A, Silicon NPN Power Transistor. Silicon D718 Transistor is fundamental components in electronic circuits, playing a crucial role in amplification, signal processing, and digital logic. They are widely used in a vast array of electronic devices, including radios, amplifiers, computer processors, and many other applications where signal control and amplification are essential.

NPN Configuration:

1. Emitter (N): The heavily doped N-type layer, which is the source of charge carriers (electrons) in the transistor.

2. Base (P): The thin P-type layer, which controls the flow of charge carriers between the emitter and collector.

3. Collector (N): The N-type layer, which collects the charge carriers that pass through the base-emitter junction.



1. Collector-Emitter Breakdown Voltage : V(BR)CEO= 120V(Min)

2. Good Linearity of hFE

3. Complement to Type 2SB688

4. Minimum Lot-to-Lot variations for robust device performance and reliable operation
