Specification

SEODescription

The 2SD1468S TO-92S transistor is an NPN bipolar junction transistor (BJT) designed for high-current amplification and switching applications in compact circuits. Housed in the TO-92S package, it supports a collector current (Ic) of up to 3A and a collector-emitter voltage (Vce) of 30V, making it suitable for driving motors, relays, or power regulation modules. Compatible replacements include 2SD1760, 2SD1590, or 2SC2383, though parameters must be verified for specific use cases. Operating within -55°C to 150°C, it integrates into consumer electronics, automotive systems, and industrial control boards. Its key strength lies in delivering high current in a small footprint, but limited power dissipation (0.5W) requires thermal management for sustained high-load operation. The TO-92S pinout simplifies direct PCB integration for cost-sensitive designs.
