2SC1431 datasheet pdf download

SavantIC Semiconductor developed the 2SC1431, a versatile silicon NPN power transistor designed for the specific demands of high-frequency power amplification. Consequently, its robust features make it a trusted choice for experienced engineers and hobbyists alike.

Core Features and Physical Design

A standout feature of this transistor is its TO-66 package. This all-metal case provides more than just physical protection; it delivers excellent thermal conductivity. As a result, the component efficiently transfers heat away from its core. From a practical, experience-based perspective, proper heatsinking is non-negotiable. This step is critical for maintaining stability and preventing thermal damage in high-power applications.

Electrically, the device boasts impressive specifications. For instance, its collector-emitter voltage (VCEO) rating of 110V offers a substantial safety margin against the voltage spikes common in RF circuits, a detail crucial for long-term reliability. Furthermore, it handles a continuous collector current of 2A and can dissipate up to 23 watts of power, making it a workhorse for medium-power tasks.
