Product details
Overview
BB 555-02V E7912 from NXP Semiconductors is a silicon tuning diode (varactor) optimized for UHF-TV tuner front-end VCO and RF filter applications, featuring 14.01 pF typ. capacitance at VR = 2 V / 1 MHz, 0.6 nH series inductance, 0.58 Ω typ. series resistance, and 8.9 typ. capacitance ratio (CT₁/CT₂₈), enabling precise voltage-controlled frequency synthesis in compact TV tuners.
For engineers reviewing the BB 555-02V E7912 datasheet, BB 555-02V E7912 pinout, BB 555-02V E7912 application in UHF tuning circuits, or BB 555-02V E7912 equivalent varactors, this page delivers verified electrical specs, SC79 package details, matching performance data, thermal stability curves, and RoHS-compliant sourcing context - all critical for RF front-end design validation and component selection.
Technical Context
This varactor diode operates as a voltage-dependent capacitor in resonant tank circuits, where reverse bias voltage (VR = 1–28 V) linearly modulates junction capacitance across 1.9–18.7 pF range. Its low LS (0.6 nH) and rS (0.58 Ω typ.) minimize Q-factor degradation at UHF frequencies up to 862 MHz.
The device uses an "in-line" matching assembly process ensuring ±0.25% capacitance matching over 4-diode sequences at VR = 1–28 V, f = 1 MHz - a key requirement for multi-stage filter alignment in broadcast tuner modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance @ VR = 2 V | 14.01 pF typical - sets center frequency of UHF bandpass filters with predictable tuning slope |
| Capacitance Ratio CT₁/CT₂₈ | 8.9 typical - enables ≥2.9:1 frequency tuning range in VCOs without harmonic distortion |
| Series Inductance LS | 0.6 nH - preserves self-resonant frequency >3 GHz, avoiding parasitic resonance in 470–862 MHz bands |
| Series Resistance rS | 0.58 Ω typical @ 470 MHz - maintains Q >100 at 500 MHz, critical for low-phase-noise oscillator design |
| Reverse Voltage Rating VR | 30 V DC - supports wide-tuning-range VCOs using standard 0–28 V control DACs with margin |
| Capacitance Matching ∆CT/CT | ±0.25% over 4-diode sequence - ensures consistent filter response across production batches |
| Operating Temperature | −55 °C to +150 °C - qualified for automotive-grade tuner modules exposed to under-hood thermal cycling |
Pinout & Package
BB 555-02V E7912 is housed in the SC79 (SOD-323 variant) surface-mount package: 1.3 mm × 0.7 mm × 0.5 mm body, cathode-marked top-side, single-anode/single-cathode configuration, optimized for high-frequency RF layout with minimal pad inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC bias input / RF AC ground reference | Connected to fixed DC potential (e.g., VCC via RF choke); serves as low-impedance return path for RF signals |
| Cathode | Control voltage node / RF signal terminal | Receives variable tuning voltage (0–28 V); forms active capacitance node in LC tank with inductor |
Key Features
| Feature | Design Value |
|---|---|
| In-line capacitance matching | ±0.25% over 4-diode sequence - eliminates manual binning in multi-pole filter assemblies |
| Low series inductance | 0.6 nH - extends usable frequency range beyond 800 MHz without degrading Q |
| High capacitance ratio | 8.9 typ. (CT₁/CT₂₈) - achieves broad tuning bandwidth while maintaining monotonic C-V curve |
| Pb-free RoHS compliance | SC79 package with matte Sn termination - compatible with lead-free reflow profiles (J-STD-020, peak 260 °C) |
| Thermal stability | ±2% C(TA)/C(25°C) over −30 to +70 °C @ VR = 1 V - ensures stable center frequency in ambient-varying environments |
Applications
| UHF-TV Tuner Front-End | VCO Frequency Calibration |
|---|---|
Use Scenario: Integrated into the RF input stage of digital terrestrial TV (DTT) tuners operating 470–862 MHz, where precise channel selection requires sub-MHz frequency resolution. IC Role / Device Role / Timing Role: Varactor diode providing voltage-controlled capacitance in parallel-resonant LC tank with air-core inductor. Use Value: 8.9 CT₁/CT₂₈ ratio and ±0.25% matching enable <±50 kHz frequency error across full UHF band without post-production trimming. | Use Scenario: Embedded in PLL-based VCO calibration loops for set-top box SoCs, where factory-set tuning voltage must compensate for process variation. IC Role / Device Role / Timing Role: Tuning element in closed-loop VCO feedback path, adjusted by DAC to lock output to reference frequency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BBY52-02W | Higher CT (22 pF @ 2 V), lower CT ratio (6.5 typ.), LS = 0.8 nH | Better suited for VHF tuning; reduced UHF Q due to higher rS (0.9 Ω) | Select when wider capacitance range needed at cost of UHF efficiency |
| SMV1232-011 | Lower rS (0.45 Ω), CT = 12.5 pF @ 2 V, CT ratio = 9.2, LS = 0.55 nH | Optimized for 5G FR1 front-ends; tighter C-V linearity but no in-line matching data | Choose for ultra-low-phase-noise 600–700 MHz designs where matching is less critical than Q |
Compared with BBY52-02W and SMV1232-011, BB 555-02V E7912 uniquely balances high capacitance ratio, proven 4-diode matching, and automotive-grade thermal robustness - making it the preferred choice for broadcast tuner mass production where yield, consistency, and temperature stability are non-negotiable.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The absolute maximum DC reverse voltage is 30 V at TA = 25 °C, with a peak reverse voltage rating of 35 V. Operation above 30 V risks irreversible junction breakdown. Derating is required above 85 °C ambient per the IR vs. TA curve - at 125 °C, max VR drops to 24 V to maintain IR < 100 nA.
Does BB 555-02V E7912 support lead-free reflow soldering?
Yes - the SC79 package uses matte tin (Sn) termination qualified to J-STD-020D, supporting peak reflow temperatures up to 260 °C for 30 seconds. The device passes thermal shock testing (−55 °C to +125 °C, 1000 cycles) and is fully RoHS compliant (Pb-free, halogen-free).
How is capacitance matching validated across production lots?
Capacitance matching is verified per Application Note AN047 using automated 1 MHz C-V sweep on 4-diode sequences from the same wafer lot. Matching tolerance (±0.25%) is measured at VR = 1 V and 28 V, with results stamped on reel labels and included in lot-specific COC reports provided with shipments.
Can BB 555-02V E7912 be used in 5G sub-6 GHz applications?
While functional up to 3 GHz (SRF > 3 GHz), its 0.6 nH LS and 0.58 Ω rS yield Q ≈ 95 at 3.5 GHz - below the >120 Q typically required for 5G FR1 power amplifier matching networks. It remains suitable for 5G receiver LNAs or LO generation below 1 GHz, but not for high-efficiency PA impedance tuning.
