FJY3007R

Overview

The FJY3007R is a single NPN pre-biased bipolar junction transistor manufactured by Fairchild Semiconductor. It utilizes an epitaxial silicon construction housed in a compact SOT-523F surface-mount package. The device features integrated biasing resistors for simplified circuit design. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current rating of 100mA, and a transition frequency of 250MHz. The component dissipates up to 200mW of power and is designed for high-speed switching applications.

Feature Summary

• Integrates base biasing resistors to reduce external component count
• NPN epitaxial silicon structure for reliable switching performance
• Compact SOT-523F surface-mount footprint for space-constrained designs

Applications

• General-purpose signal switching circuits
• Low-power digital logic interface stages
• Consumer electronics control boards

Procurement Notes

Verify the specific revision code on the datasheet, as legacy components may have updated pinout or thermal characteristics compared to older production runs. Confirm that the SOT-523F package dimensions align with your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides traceability documentation for this discontinued series.

Selection Notes

Select this component when a small form factor NPN switch with built-in biasing is required. The 50V rating suits low-voltage logic systems. Consider the 100mA current limit for load driving capabilities. The 250MHz frequency supports moderate-speed digital signals. Evaluate thermal management needs given the 200mW dissipation limit in the small package.
