Product details
Overview
BFR360FH6327XTSA1 from Infineon is a silicon NPN RF bipolar transistor in SOT343 package, optimized for low-noise amplification at 1.8 GHz with NFmin = 0.9 dB, Gms = 21.5 dB, OIP3 = 24.5 dBm, and 1 kV HBM ESD robustness. It serves as the active gain element in broadband LNA stages for DVB-T and FM/AM radio front-ends.
For engineers reviewing the BFR360FH6327XTSA1 datasheet, BFR360FH6327XTSA1 pinout, BFR360FH6327XTSA1 application, or BFR360FH6327XTSA1 equivalent, key selection criteria include noise figure at 5 mA bias, transducer gain at 20 mA, output IP3 linearity, ESD tolerance, and SOT343 thermal resistance (RthJS = 290 K/W).
Technical Context
This grounded-emitter (SIEGET™) RF transistor delivers high-frequency performance via optimized epitaxial base design and low-parasitic SOT343 packaging. Its fT = 21–30 GHz enables stable operation up to 3 GHz with verified small-signal gain and noise behavior.
The device integrates an on-chip ESD protection structure rated to 1 kV HBM, enabling robust handling in automated assembly without external protection. Bias conditions are defined for VCE = 2 V, with DC current gain hFE = 50–170 at IC = 20 mA and pulse measurement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| NFmin | 0.9 dB at 1.8 GHz, 2 V, 5 mA - sets minimum achievable noise floor in LNA input stage |
| Gms | 21.5 dB at 1.8 GHz, 2 V, 20 mA - determines small-signal power gain under standard RF bias |
| OIP3 | 24.5 dBm at 1.8 GHz, 2 V, 20 mA - defines third-order intermodulation headroom in multi-carrier systems |
| fT | 21–30 GHz - establishes upper frequency limit for useful current gain |
| ESD rating | 1 kV HBM - ensures survivability during PCB handling and reflow without external clamps |
| RthJS | 290 K/W - limits junction temperature rise under 250 mW max dissipation at TS ≤ 77 °C |
| hFE | 50–170 at VCE = 3.5 V, IC = 20 mA - supports stable DC bias network design |
Pinout & Package
SOT343 surface-mount plastic package with 4 terminals, 1.3 mm × 1.3 mm footprint, 0.95 mm height, and gull-wing leads. Thermal path optimized via exposed emitter pad (Pin 2 and Pin 4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | RF input node for common-emitter configuration; requires DC blocking and impedance matching |
| 2 (E) | Emitter | AC ground reference and primary thermal path; connected to PCB ground plane for RthJS control |
| 3 (C) | Collector | RF output node; biased at 2 V via RF choke or decoupled supply rail |
| 4 (E) | Emitter | Second emitter terminal for enhanced thermal conduction and low-inductance grounding |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise architecture | SIEGET™ grounded-emitter topology reduces base resistance and flicker noise, enabling NFmin ≤ 1.4 dB up to 3 GHz |
| High linearity | OIP3 ≥ 24.5 dBm at 1.8 GHz ensures minimal distortion in DAB/DMB broadcast receivers with adjacent-channel interference |
| ESD-hardened structure | Integrated diode-based protection achieves 1 kV HBM without degrading RF performance or requiring external TVS |
| Thermally optimized package | Dual-emitter-pin SOT343 reduces thermal resistance by ~35% vs. standard SOT343, supporting continuous 20 mA operation |
Applications

Use Value: fT ≥ 21 GHz ensures sufficient gain margin at second harmonic, minimizing LO leakage into RF port. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar RF bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BFP540ESDH6327XTSA1 | Same die, identical electrical specs, identical SOT343 pinout and marking (AUs), but marked "BFP540ESD" instead of "BFR360F" | Qualified per AEC-Q101; used in automotive-grade LNB modules where extended temperature validation required | Select when AEC-Q101 qualification is mandatory and full traceability to Infineon's industrial release is needed |
| NE85633 | Lower fT (12 GHz), higher NFmin (1.3 dB at 1.8 GHz), no integrated ESD protection, TO-92 package | Legacy AM/FM receiver designs with through-hole assembly and external ESD safeguards | Choose only for cost-sensitive, non-automated production where SOT343 reflow compatibility is not required |
Compared with BFR360FH6327XTSA1, BFP540ESDH6327XTSA1 offers identical RF performance with automotive qualification overhead, while NE85633 trades linearity and ESD robustness for lower unit cost and through-hole compatibility - making the former suitable for high-reliability embedded RF, the latter for legacy consumer audio.

FAQ
What is the maximum DC collector current rating for BFR360FH6327XTSA1?
The absolute maximum DC collector current is 80 mA at TA = 25 °C, but the recommended operating range is 5–20 mA for optimal noise and linearity performance. Exceeding 20 mA increases junction temperature and degrades NFmin and OIP3, especially without adequate PCB copper area for heat dissipation.
Can BFR360FH6327XTSA1 be used in 5 V supply applications?
No - its absolute maximum VCEO is 4.5 V with open base, and safe DC operation is limited to VCE ≤ 3.5 V. At 5 V, risk of avalanche breakdown increases significantly, particularly above 25 °C ambient. For 5 V systems, use a series resistor or LDO to regulate collector voltage to ≤3.5 V.
Is the SOT343 package lead-free and RoHS-compliant?
Yes - BFR360FH6327XTSA1 uses lead-free matte tin plating on gull-wing leads and complies with RoHS Directive 2011/65/EU and REACH SVHC regulations. The molding compound is halogen-free, and the device meets JEDEC J-STD-020 moisture sensitivity level MSL3 (floor life = 168 hours at 30 °C/60% RH).
How does the dual-emitter-pin configuration affect PCB layout?
The dual emitter pins (2 and 4) must be connected to the same low-impedance RF ground plane with minimum trace length and direct thermal vias. Separating them or routing one to a different net introduces asymmetry, unbalances the SIEGET™ structure, and degrades noise figure and gain flatness above 1 GHz.
