FJX4013RTF

Overview

The FJX4013RTF is a PNP epitaxial silicon transistor featuring built-in bias resistors, manufactured by onsemi under the Fairchild Semiconductor lineage. It operates with a collector-emitter voltage of -50 V and a collector current of -100 mA. The device integrates a base resistor (R1) of approximately 2.2 kΩ and an emitter-base resistor (R2) of 47 kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 68 at -5 mA, a saturation voltage of -0.3 V at -10 mA, and a transition frequency of 200 MHz. Packaged in SOT-323, it supports junction temperatures up to 150 °C.

Feature Summary

• Integrated bias network consisting of a base resistor and an emitter-base resistor for simplified circuit design.
• High-speed switching capability supported by a 200 MHz current gain bandwidth product.
• Low saturation voltage ensures efficient performance in driver and interface applications.

Applications

• Switching circuits
• Inverter logic stages
• Interface circuits
• Driver circuits

Procurement Notes

Verify the manufacturer origin carefully, as the component originates from Fairchild Semiconductor, which was acquired by onsemi. Confirm that the specific ordering suffix 'TF' corresponds to the required tape-and-reel packaging format intended for automated surface-mount assembly processes.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required to reduce external component count. Ensure the application demands a maximum collector current within 100 mA and a voltage rating compatible with -50 V limits. Verify thermal constraints align with the 200 mW power dissipation limit in the SOT-323 package.

Part Context

This part serves as the complementary counterpart to the NPN type FJX3013R within the same family of bias-resistor built-in transistors. Both devices share similar electrical profiles and packaging, allowing for symmetrical push-pull or differential configurations in switching and amplification designs.

Replacement Considerations

Direct substitutes include the FJX3013R for complementary NPN requirements. Other generic PNP transistors with built-in resistors may function but require verification of pinout compatibility and exact resistance values to ensure circuit stability.
