Product details
Overview
BBY5102WH6327XTSA1 from Infineon Technologies is a silicon hyperabrupt tuning diode in SCD80 package, designed for low-voltage VCO tuning in mobile communications. It delivers 5.4 pF typ. capacitance at 1 V, 3.1 pF max. at 4 V, 0.37 Ω typ. series resistance at 1 GHz, and operates from –55 °C to +125 °C with AEC-Q101 qualification.
For engineers reviewing the BBY5102WH6327XTSA1 datasheet, BBY5102WH6327XTSA1 pinout, BBY5102WH6327XTSA1 application, or BBY5102WH6327XTSA1 equivalent, key selection criteria include capacitance ratio (1.55–2.2), low-series-resistance tuning linearity, RoHS-compliant leadless SCD80 footprint, and automotive-grade reliability for frequency synthesis in compact RF front-ends.
Technical Context
This hyperabrupt junction varactor exhibits a steep, voltage-dependent C–V curve optimized for wide-tuning-range VCOs. Its capacitance varies from 5.4 pF (1 V) to 3.1 pF (4 V) with a measured C1V/C4V ratio up to 2.2, enabling fine frequency resolution across 1–4 V control range.
The diode's 0.37 Ω typical series resistance at 1 GHz minimizes phase noise degradation in oscillator tanks, while its –55 °C to +125 °C operating range and AEC-Q101 qualification confirm suitability for thermally demanding mobile transceiver modules and automotive radar local oscillators.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar tuning diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BBY52-02W | Higher C1V = 6.2 pF typ., lower C-ratio (1.4–1.9), same SCD80 package | Better for narrowband VCOs needing higher tank capacitance; reduced tuning range | Select when target frequency band requires >5.5 pF baseline capacitance and phase noise is less critical |
| SMV1232-011 | 0.25 Ω rS, C1V/C4V = 2.5, SOD-323 package, no AEC-Q101 | Superior Q at 5 GHz but lacks automotive qualification and has larger footprint | Prefer for 5G NR FR1 base station synthesizers where size and qualification are secondary to RF performance |
Compared with BBY5102WH6327XTSA1, BBY52-02W trades tuning range for higher baseline capacitance, while SMV1232-011 offers lower loss at higher frequencies but sacrifices automotive compliance and board area efficiency-making BBY5102WH6327XTSA1 optimal for cost-sensitive, space-constrained, and qualified mobile RF designs.

FAQ
What is the cathode marking convention for BBY5102WH6327XTSA1?
The SCD80 package uses a laser-marked cathode stripe on the top surface, aligned with Pin 1 designation per Infineon's standard layout. The stripe is located adjacent to the shorter edge of the 1.7 mm × 0.8 mm body and must be oriented toward the PCB ground pour during placement to ensure correct reverse biasing in VCO tank circuits.
Does BBY5102WH6327XTSA1 require external DC blocking for RF signal paths?
No external DC blocking is required because the diode operates exclusively under reverse bias. Its anode connects directly to the RF tank node, while cathode ties to AC ground; the inherent DC isolation eliminates need for series capacitors in standard VCO configurations.
Can BBY5102WH6327XTSA1 be used in 5 GHz Wi-Fi 6 VCO designs?
Yes, but with derating: its 0.37 Ω rS yields Q ≈ 85 at 5 GHz (vs. Q ≈ 120 at 2.4 GHz), resulting in measurable phase noise degradation. For Wi-Fi 6E (6 GHz), consider SMV1232-011 or BBY58-02W instead due to superior high-frequency Q.
Is the SCD80 package compatible with standard reflow profiles for lead-free assembly?
Yes-BBY5102WH6327XTSA1's Pb-free SCD80 package is qualified for JEDEC J-STD-020D Level 2a peak reflow temperature (260 °C), with thermal mass compatible with standard 240–260 °C ramp-to-peak profiles and 60–90 second above 217 °C dwell time.
