2SC3914-TB-E

Single Bipolar Transistors Overview

The onsemi 2SC3914-TB-E is a single NPN bipolar junction transistor (BJT) designed for surface mount applications. It features a maximum collector current of 500 mA and a collector-emitter voltage rating of 50 V. The device has a power dissipation capacity of 200 mW and operates within a temperature range of -55 °C to 150 °C. Packaged in the CP case, it integrates internal bias resistors with values of R1 at 2.2 kΩ and R2 at 10 kΩ.

Single Bipolar Transistors Feature Summary

• Integrated bias network with fixed resistor values for simplified circuit design
• High current handling capability suitable for switching loads
• Surface-mount package optimized for automated assembly processes

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Driver stages for low-power loads
• Signal switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TB-E' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and marking codes. Ensure that the integrated bias resistor values match the target circuit requirements before procurement, as these are fixed parameters.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN switch with built-in biasing is required. The 500 mA current rating supports moderate load driving, while the 50 V voltage rating limits suitability to low-voltage systems. The surface-mount form factor aids in reducing board space compared to through-hole alternatives.

Single Bipolar Transistors Part Context

This part belongs to the family of pre-biased transistors manufactured by onsemi. These devices combine a BJT with internal resistors to reduce external component count. The 2SC3914 variant specifically utilizes the CP package, distinguishing it from other packages in the broader product line.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitutes include the 2SC3914-VY. Verify pinout compatibility and electrical ratings when substituting. Other generic NPN transistors may require additional external biasing components.
