Disadvantages: - Limited maximum collector current (100mA) may restrict certain applications. - Maximum power dissipation of 200mW may limit usage in high-power circuits.

Working Principles

The V103YLF is an NPN transistor, which means it consists of three layers of semiconductor material. When a small current is applied to the base pin (B), it controls the flow of a larger current between the collector (C) and emitter (E) pins. This amplification process allows the transistor to amplify weak signals.
