Product details

Overview

BFR 380T E6327 from Infineon Technologies is an NPN silicon RF transistor in SC75 package, rated for 6 V V_CEO, 80 mA I_C, and 380 mW P_tot, optimized for low-phase-noise oscillators up to 3.5 GHz with 1.1 dB noise figure at 1.8 GHz and 14 GHz f_T.

For engineers reviewing the BFR 380T E6327 datasheet, BFR 380T E6327 pinout, BFR 380T E6327 application, or BFR 380T E6327 equivalent, key selection criteria include verified 1.1 dB F_min at 1.8 GHz, 14 GHz transition frequency, SC75 thermal resistance of 220 K/W, and ESD-sensitive handling requirements.

Technical Context

This RF transistor employs a high-frequency Gummel-Poon SPICE model (NF = 1.107, BF = 116.4, f_T = 14 GHz) with validated parasitic network (L1 = 0.762 nH, C1 = 62 fF, Ccb = 0.5 pF typ.) for accurate small-signal simulation up to 6 GHz.

It operates with low-voltage biasing (V_CE = 3 V, I_C = 40 mA), delivers 12.5 dB maximum available gain at 1.8 GHz, and achieves 29.5 dBm OIP3 - enabling wide dynamic range in narrowband RF front-ends and local oscillator stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	6 V - Maximum safe collector-emitter voltage under open-base condition; defines DC bias headroom in oscillator and amplifier designs.
f_T	14 GHz typ. - Transition frequency confirming usable gain beyond 3.5 GHz; supports stable operation in UHF/low-L-band applications.
F_min	1.1 dB at 1.8 GHz - Minimum noise figure measured with optimal source impedance; critical for receiver LNA and LO buffer stages.
P_tot	380 mW - Total power dissipation limit at T_S = 66°C; constrains continuous RF output power in Class-A biased circuits.
C_cb	0.5 pF typ. - Collector-base capacitance at 5 V; directly impacts Miller effect and tuning range in VCO tank circuits.
OIP3	29.5 dBm - Third-order output intercept point at 1.8 GHz; quantifies linearity for multi-tone signal handling in transceivers.
R_thJS	220 K/W - Junction-to-soldering-point thermal resistance; determines temperature rise per watt in PCB-mounted SC75 layout.

Pinout & Package

Package: SC75 (SOT-323), 3-pin surface-mount plastic package with standard lead finish and moisture sensitivity level (MSL) 1.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control electrode for current amplification; requires stable DC bias and RF decoupling due to low input impedance (~kΩ range).
2	Emiter (E)	Common reference node in common-base configuration; grounded in many oscillator topologies to minimize parasitic inductance.
3	Collector (C)	RF output node in common-emitter mode; connects to tank circuit or matching network; carries full RF current and heat.

Key Features

Feature	Design Value
Low-phase-noise oscillator support	Validated 1.1 dB F_min at 1.8 GHz and 14 GHz f_T enable stable, spectrally pure LO generation up to 3.5 GHz.
Wide dynamic range capability	29.5 dBm OIP3 and 16 dBm P1dB ensure linear operation with strong interferers in cellular and ISM band receivers.
Low-voltage RF operation	Specified performance at V_CE = 3 V enables compatibility with 3.3 V supply rails without external level-shifting.
ESD-protected design	Class 1B HBM rating (per JEDEC JESD22-A114); requires grounded wrist strap and conductive foam during handling.

Applications

Cellular Front-End LNA

ISM Band Oscillator

Use Scenario: Low-noise amplification of 1.8 GHz LTE receive signals in smartphone transceiver modules.

IC Role / Device Role / Timing Role: Common-emitter configured RF transistor acting as first-stage LNA with matched 50 Ω input impedance.

Use Value: 1.1 dB noise figure preserves SNR in weak-signal conditions; 12.5 dB G_ma provides sufficient gain before mixer stage.

Use Scenario: Voltage-controlled oscillator core for 2.4 GHz Wi-Fi access points operating in industrial environments.

IC Role / Device Role / Timing Role: Common-base configured transistor sustaining oscillation in Clapp or Colpitts topology with varactor tuning.

Use Value: Low C_cb (0.5 pF) minimizes frequency pulling; high f_T ensures loop stability across temperature and process variation.

UHF RFID Reader PA

GPS/GLONASS L1 Band Buffer

Use Scenario: Final-stage driver amplifier in 860–960 MHz RFID readers requiring +27 dBm output with harmonic suppression.

IC Role / Device Role / Timing Role: Class-A biased RF transistor delivering broadband gain with external harmonic filtering.

Use Value: 380 mW P_tot supports 200–250 mW saturated output; 14 GHz f_T ensures gain margin above fundamental frequency.

Use Scenario: Local oscillator buffer driving quadrature mixer in dual-band GNSS receivers.

IC Role / Device Role / Timing Role: Common-collector emitter follower isolating VCO from load variations while preserving phase integrity.

Use Value: Low 1.1 dB F_min prevents added phase noise; SC75 package enables compact layout adjacent to RF IC.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN RF transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BFP 640F E6327	Higher f_T (25 GHz), lower C_cb (0.35 pF), same SC75 package and 1.1 dB F_min.	Better suited for 5 GHz Wi-Fi and higher-frequency VCOs where bandwidth exceeds 3.5 GHz.	Select when >4 GHz operation or tighter phase noise budget is required; otherwise BFR 380T E6327 offers cost advantage.
MRF581	TO-92 package, higher P_tot (500 mW), but higher F_min (1.5 dB at 1.8 GHz) and lower f_T (8 GHz).	Preferred for through-hole prototyping or legacy designs where thermal mass improves reliability at elevated ambient.	Choose only if SC75 footprint is incompatible or board-level rework tolerance is critical; not drop-in compatible.

Compared with BFP 640F E6327 and MRF581, the BFR 380T E6327 balances low-phase-noise performance, SC75 miniaturization, and 3.5 GHz operational ceiling - making it optimal for cost-sensitive, space-constrained 1.8–2.4 GHz RF subsystems.

FAQ

Is the BFR 380T E6327 RoHS compliant?

Yes, the BFR 380T E6327 meets RoHS Directive 2011/65/EU and is lead-free with matte tin (Sn) termination on all leads. The SC75 package uses halogen-free molding compound and complies with IPC/JEDEC J-STD-020D moisture sensitivity level 1.

What is the recommended PCB layout for optimal RF performance?

Use a solid ground plane beneath the SC75 footprint, keep emitter pad connection direct and short (<1 mm), place 100 pF bypass capacitor within 2 mm of collector, and route base bias traces away from RF paths to avoid coupling. Thermal vias under the collector pad improve R_thJA by ~30%.

Can the BFR 380T E6327 be used in common-base configuration?

Yes - the device is characterized and widely applied in common-base mode for wideband amplifiers and oscillator cores. Pin 2 (emitter) serves as AC ground, pin 1 (base) as input, and pin 3 (collector) as output; S-parameters confirm stable gain up to 3 GHz in this configuration.

Does Infineon provide SPICE models for the BFR 380T E6327?

Yes - a validated Gummel-Poon SPICE model is provided in Berkeley SPICE 2G.6 syntax, including all 32 parameters (e.g., BF = 116.376, NF = 1.107, CJC = 840 fF). Model files are available via Infineon's official support portal and pre-integrated into Keysight PathWave ADS and Cadence Virtuoso libraries.
