Product details
Overview
BB659C-02V from Infineon Technologies is a silicon hyperabrupt junction varactor diode optimized for VHF tuning in TV and VTR tuners. It delivers a 15.3:1 capacitance ratio (CT₁/CT₂₈), 2.4–2.75 pF capacitance at 28 V, 0.6 Ω series resistance at 5 V/470 MHz, and 0.6 nH series inductance in SC79 package.
For engineers reviewing the BB659C-02V datasheet, BB659C-02V pinout, BB659C-02V application, or BB659C-02V equivalent, key selection criteria include VHF tuning linearity, low RF loss at 470 MHz, tight capacitance matching across diode arrays, and RoHS-compliant SMD packaging for high-volume tuner module assembly.
Technical Context
This hyperabrupt varactor uses an optimized doping profile to achieve near-linear C–V response over 1–28 V, enabling precise frequency control in wideband VHF oscillators and filter tuning networks. Its 0.6 nH LS and 0.6 Ω rS minimize Q degradation above 100 MHz.
The device is fabricated using Infineon's "in-line" matching assembly process-four diodes per sequence-achieving ±0.5% ∆CT/CT matching across 1–28 V, critical for multi-stage tuner alignment and phase-stable PLL loop filters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance Ratio CT₁/CT₂₈ | 15.3:1 - enables >100 MHz tuning bandwidth with monotonic frequency vs. voltage behavior |
| Capacitance at 28 V | 2.4–2.75 pF - sets upper limit of resonant tank frequency in VHF oscillator designs |
| Series Resistance rS | 0.6 Ω typ. @ 5 V, 470 MHz - limits insertion loss and Q-factor degradation in RF matching networks |
| Series Inductance LS | 0.6 nH - contributes <0.2 Ω reactance up to 200 MHz, preserving effective tuning range |
| Reverse Voltage VR | 30 V DC - supports bias headroom for AGC-controlled tuning in broadcast receiver front-ends |
| Capacitance Matching ∆CT/CT | ±0.5% max. (4-diode sequence) - ensures consistent tracking across multi-varactor filter banks |
Pinout & Package
SC79 surface-mount package: single-anode, cathode-marked top-side stripe; 1.3 mm × 0.7 mm footprint; 0.8 mm height; Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC bias input / RF AC ground reference | Connected to tuning voltage source; forms low-impedance return path for RF signals via decoupling capacitor |
| Cathode | RF signal node / variable capacitance terminal | Connected directly to LC tank or filter node; voltage-dependent depletion capacitance modulates resonance |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BB659C | Same die, SCD80 package (1.7 × 0.9 mm); 0.6 nH LS, 0.6 Ω rS; no marking distinction for -02V variant | Less compact footprint; higher thermal mass; identical electrical specs but different board layout requirements | Select when legacy SCD80 land pattern is fixed and SC79 rework is not feasible |
| BB639C | Same family, SOD323 package; 1.8 nH LS, 0.7 Ω rS; lower C-ratio (14.2:1); 7-diode matching sequence | Higher RF loss above 100 MHz; wider capacitance tolerance; intended for cost-sensitive consumer TV modules | Choose only if design operates ≤80 MHz and matching tolerance >±1% is acceptable |
Compared with BB659C-02V, BB659C requires larger PCB area but offers identical RF performance, while BB639C trades off Q and matching precision for lower cost and broader availability in high-volume consumer tuner designs.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The BB659C-02V is rated for 30 V DC reverse voltage at 25°C ambient. At 85°C, IR rises to 200 nA, but VR remains limited to 30 V to prevent junction breakdown. Derating is not specified; sustained operation above 30 V risks irreversible avalanche damage and capacitance drift.
How does the 0.6 nH series inductance affect VHF tuning performance?
The 0.6 nH LS introduces +j37 Ω reactance at 100 MHz and +j117 Ω at 310 MHz, limiting usable tuning range to ≤230 MHz in practical LC tanks. Above this, effective capacitance deviates significantly from DC C–V curves, requiring layout-aware compensation in oscillator design.
Can BB659C-02V be substituted for BB659C in existing SCD80 footprints?
No - BB659C-02V uses SC79 (1.3 × 0.7 mm), while BB659C uses SCD80 (1.7 × 0.9 mm). Pad dimensions, solder paste volume, and thermal profile differ. Direct substitution causes tombstoning or insufficient solder joint strength; redesign of land pattern and stencil is required.
Is temperature coefficient of capacitance (TCC) specified for this part?
Yes - TCC is plotted in Figure 3 of the datasheet, ranging from −1.2×10⁻⁴/°C at 1 V to −0.3×10⁻⁴/°C at 28 V. This negative, voltage-dependent coefficient must be compensated in temperature-stable VCO designs using NPO capacitors or digital calibration lookup tables.
