BFU520XRR

Overview

The BFU520XRR is an NPN wideband silicon RF transistor from the BFU5 family, designed for high-speed, low-noise applications up to 2 GHz. It utilizes a plastic SOT143R package with reverse pinning and dual emitters. Key electrical parameters include a collector-base voltage of 24 V (open emitter) or 30 V (shorted base), a collector-emitter voltage of 12 V (open base) or 24 V (shorted base), and a maximum collector current of 30 mA. The device features a minimum noise figure of 0.65 dB at 900 MHz and a maximum stable gain of 20 dB at 900 MHz. Transition frequency is typically 10.5 GHz.

Feature Summary

AEC-Q101 qualified for automotive reliability
Low noise figure optimized for sensitive signal reception
High breakdown voltage capability for robust operation
Dual-emitter SOT143R package design

Applications

Broadband amplifiers operating up to 2 GHz
Low noise amplifiers for ISM band applications
ISM band oscillators
Circuits requiring high supply voltages

Procurement Notes

Verify the specific suffix 'RR' against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the component matches the SOT143R package outline and reverse pinning configuration detailed in the datasheet. Confirm that the AEC-Q101 qualification status meets the requirements for the intended application environment before finalizing procurement.

Selection Notes

Select this component when designing circuits that require low noise performance combined with high breakdown voltage capabilities. The dual-emitter SOT143R package is suitable for surface-mount assembly where space is constrained. Consider the thermal resistance characteristics and power dissipation limits when determining heat sinking requirements for continuous operation.

Part Context

The BFU520XRR belongs to the BFU5 series of NPN wideband silicon RF transistors manufactured by NXP Semiconductors. This series is engineered for small-signal to medium-power applications across radio frequencies up to 2 GHz. The BFU520XR variant specifically offers a balance of low noise and high gain, making it a standard choice for RF front-end designs in communication systems.
