Overview
The FJX3002RTF is a digital NPN silicon epitaxial transistor manufactured by onsemi. It integrates internal biasing resistors to simplify circuit design and reduce component count. The device is housed in an SOT-323-3 surface-mount package, suitable for automated assembly processes. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current rating of 100 mA. The typical input resistance is 47 kOhms with a resistor ratio of 2.1. Power dissipation is rated at 200 mW, and the unit operates within a temperature range of -55°C to +150°C.
Feature Summary
- Integrated biasing network reduces external component requirements
- High-density SMD packaging for space-constrained applications
- NPN configuration with epitaxial silicon construction
Applications
- General-purpose switching circuits
- Driver stages for logic interfaces
- Signal level translation
Procurement Notes
Verify the specific suffix RTF against the official onsemi datasheet to confirm reel packaging and tape dimensions. Confirm RoHS compliance status through the manufacturer's latest product compliance documentation before finalizing procurement plans.
Selection Notes
Select this component when a compact NPN digital transistor with integrated base resistors is required. Ensure the 50 V collector-emitter voltage and 100 mA current ratings exceed the maximum circuit demands. Verify that the SOT-323-3 footprint matches the PCB layout constraints.
Part Context
This part belongs to the FJX3008R series of digital transistors from onsemi. These devices are designed as drop-in replacements for discrete resistor-transistor networks, offering improved performance consistency and reduced board space compared to individual components.
Replacement Considerations
Check for direct pin-compatible substitutes within the same FJX series or equivalent offerings from other manufacturers. Verify that any replacement maintains the 50 V VCEO rating and similar hFE characteristics to ensure circuit compatibility.
