Product details
Overview
BBY5502VH6327XTSA1 from Infineon Technologies is a hyperabrupt silicon tuning diode in SC79 package, optimized for VCOs in mobile communications equipment. It delivers 17.5–19.6 pF capacitance at 1 V reverse bias, <0.4 Ω series resistance at 470 MHz, and a capacitance ratio CT₂/CT₁₀ ≥ 2.0, enabling precise low-voltage frequency tuning.
For engineers reviewing the BBY5502VH6327XTSA1 datasheet, BBY5502VH6327XTSA1 pinout, BBY5502VH6327XTSA1 application, or BBY5502VH6327XTSA1 equivalent, key selection criteria include its hyperabrupt C–V profile, low rS for high-Q VCO design, tight ±1% capacitance spread at 1–10 V, and RoHS-compliant SC79 surface-mount packaging.
Technical Context
This diode employs a hyperabrupt junction profile to achieve near-linear voltage-to-capacitance response over 1–10 V, critical for stable VCO gain (MHz/V) control. Its low series resistance (0.15 Ω typ. at 5 V, 470 MHz) minimizes phase noise degradation in oscillator tank circuits.
Designed specifically for mobile RF front-ends, it operates across –55 °C to +150 °C with IR ≤ 3 nA at 15 V/25 °C and ≤100 nA at 15 V/85 °C - ensuring reliability in thermally constrained handheld transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance @ 1 V | 17.5–19.6 pF - sets VCO center frequency and tuning range baseline |
| Capacitance @ 10 V | 5.5–6.5 pF - defines maximum tuning voltage limit and minimum oscillation frequency |
| Capacitance Ratio CT₂/CT₁₀ | 2.0–3.0 - determines usable VCO tuning linearity and frequency deviation per volt |
| Series Resistance rS | 0.15–0.4 Ω @ 470 MHz - directly impacts tank Q-factor and phase noise floor |
| Reverse Current IR | ≤3 nA @ 15 V, 25 °C - ensures minimal leakage-induced frequency drift in bias networks |
| Max Reverse Voltage VR | 16 V - sets absolute upper limit for tuning voltage rail design margin |
| Operating Temp Range | –55 °C to +150 °C - supports operation in sealed mobile handset RF modules |
Pinout & Package
SC79 (SOD-523) single-anode, cathode-marked plastic surface-mount package; 1.3 mm × 0.7 mm footprint, 0.8 mm height, cathode indicated by white band on top surface.

Key Features
| Feature | Design Value |
|---|---|
| Hyperabrupt junction profile | Enables near-linear C–V response from 1–10 V, reducing VCO gain variation across tuning range |
| Low series resistance | 0.15 Ω typical at 470 MHz preserves tank Q > 100 in 800–2200 MHz VCO designs |
| Tight capacitance spread | ±1% tolerance at 1 V and 10 V ensures predictable VCO center frequency and tuning slope batch-to-batch |
| Low-voltage tuning capability | Full 3:1 capacitance range achieved below 10 V, compatible with 3.3 V and 5 V bias rails |
| Pb-free RoHS-compliant package | SC79 meets JEDEC MS-012 standards and enables lead-free reflow assembly without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar tuning diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54C,115 | Lower C range (9–12 pF), higher rS (>1.5 Ω), abrupt (not hyperabrupt) junction | Suitable for basic oscillator trim, not linear VCO tuning | Select only when Kvco linearity is non-critical and Q > 50 is acceptable |
| BBY65-02V,115 | Higher C (25–28 pF @ 1 V), same SC79 package, but lower CT₂/CT₁₀ ratio (1.6–1.9) | Better for wide-range low-frequency VCOs (e.g., sub-GHz ISM), less suited for 2+ GHz mobile bands | Prefer for cost-sensitive 433 MHz RKE; avoid where 1–10 V linearity is required |
Compared with BAT54C and BBY65-02V, BBY5502VH6327XTSA1 uniquely balances high C-linearity, ultra-low rS, and tight spread - making it the only choice for production-grade mobile VCOs demanding <±5 kHz frequency error over temperature and voltage.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The absolute maximum reverse voltage is 16 V at 25 °C. For reliable long-term operation in mobile VCOs, Infineon specifies 10 V as the maximum recommended tuning voltage to maintain linearity and minimize aging effects. Exceeding 10 V increases capacitance hysteresis and accelerates parameter drift over temperature cycles.
How does the capacitance change with temperature at 1 V bias?
At 1 V reverse bias, capacitance drift is ±1% over –55 °C to +150 °C, with worst-case deviation occurring at extremes: –1% at –55 °C and +1% at +150 °C. This is measured relative to 25 °C baseline and confirmed per Infineon's characterization data sheet BBY55-DS-v02_00-EN.
Can BBY5502VH6327XTSA1 be used in DC-coupled tuning configurations?
No - this diode must operate under reverse bias only. Forward conduction degrades junction integrity and causes irreversible capacitance shift. All tuning circuits must ensure anode is held at equal or higher potential than cathode; a series blocking capacitor or high-impedance bias network is mandatory for AC-coupled control voltage injection.
Is the SC79 package compatible with standard SMT reflow profiles?
Yes - the Pb-free SC79 package is qualified for IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C for 30 seconds. Thermal pad layout follows Infineon's recommended footprint (1.3 mm × 0.7 mm, 0.13 mm stencil aperture), and no underfill is required for mechanical reliability.
