Product details
Overview
BB 555-02V E7902 from NXP Semiconductors is a silicon tuning diode (varactor) optimized for UHF-TV tuner front-ends, featuring 14.01 pF typical capacitance at VR = 2 V / 1 MHz, 0.6 nH series inductance, and 0.58 Ω typical series resistance at 470 MHz - enabling high-Q resonant tank performance in compact VHF/UHF RF filters and local oscillator circuits.
For engineers reviewing the BB 555-02V E7902 datasheet, BB 555-02V pinout, BB 555-02V application, or BB 555-02V equivalent, key selection criteria include capacitance ratio CT1/CT28 ≥ 8.2, matching tolerance ∆CT/CT ≤ 1% across 4-diode sequences, low-temperature coefficient (±10⁻⁴ /°C at VR = 1 V), and RoHS-compliant SC79 package compatibility with high-frequency reflow profiles.
Technical Context
This varactor diode operates under reverse-bias conditions to provide voltage-controlled capacitance, with CT varying from 17.5 pF (VR = 1 V) to 1.9 pF (VR = 28 V) at 1 MHz - delivering a usable tuning range of 8.2:1. Its low LS (0.6 nH) and rS (0.58 Ω typ.) minimize parasitic resonance shift and insertion loss in LC tank networks.
The device employs an "in-line" matching assembly process, ensuring tight capacitance matching (∆CT/CT ≤ 1%) across four consecutive diodes - critical for multi-stage tuning banks in broadcast TV tuners where phase coherence and channel selectivity depend on inter-device consistency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance @ VR = 2 V | 14.01 pF typical - sets center frequency of UHF tuner VCO tanks with predictable bias-voltage sensitivity |
| Capacitance Ratio CT1/CT28 | 8.2–9.8 - enables >3-octave tuning range without switching capacitors in wideband TV front-ends |
| Series Inductance LS | 0.6 nH - limits self-resonant frequency degradation above 1 GHz, preserving Q in UHF bands |
| Series Resistance rS | 0.58 Ω typical @ 470 MHz - reduces thermal noise and insertion loss in high-Q resonators |
| Reverse Voltage Rating VR | 30 V DC - supports tuner AGC and fine-tuning bias rails up to ±15 V with safety margin |
| Capacitance Matching ∆CT/CT | ≤1% over 4-diode sequence - ensures amplitude/phase tracking in multi-varactor tuning arrays |
| Operating Temperature | −55 °C to +150 °C - sustains stable C-V curve across automotive and industrial tuner environments |
Pinout & Package
BB 555-02V E7902 is housed in the SC79 (SOD-323 variant) surface-mount package: 1.3 mm × 0.7 mm × 0.9 mm, cathode-marked with laser dot, compatible with standard 2 mm pitch tape-and-reel (8,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|

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 (5.5:1), LS = 0.8 nH | Better for VHF tuning; insufficient UHF range coverage alone | Select when wider absolute capacitance needed at lower frequencies, not for full UHF span |
| SMV1232-011 | Lower rS (0.45 Ω), higher VR (35 V), CT = 12.5 pF @ 2 V, LS = 0.55 nH | Optimized for cellular PA tuning; tighter rS spec but narrower temp range (−40 to +125 °C) | Prefer for LTE/WiFi front-end tuning where ultra-low loss dominates over temperature robustness |
Compared with BBY52-02W and SMV1232-011, BB 555-02V E7902 uniquely balances UHF-wide tuning range (8.2:1), production-grade matching (≤1%), and extended temperature capability (−55 to +150 °C), making it optimal for broadcast tuner modules requiring long-term reliability and batch consistency.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The BB 555-02V E7902 has a DC reverse voltage rating (VR) of 30 V at 25 °C, with a peak reverse voltage (VRM) of 35 V. For reliable long-term operation, sustained bias should remain ≤28 V to maintain specified capacitance range and avoid accelerated aging - especially above 85 °C where IR rises to 200 nA.
How does capacitance matching work across multiple BB 555-02V units?
BB 555-02V uses an "in-line" matching assembly process where four consecutive diodes from the same wafer lot are binned to ≤1% ∆CT/CT over VR = 1–28 V. This is verified per Application Note AN047 and applies only to devices marked with identical date codes and reel positions - not random units from different reels.
Can BB 555-02V E7902 be used in series-tuned configurations?
Yes - its low series resistance (0.58 Ω typ.) and inductance (0.6 nH) make it suitable for both shunt-tuned (parallel-resonant) and series-tuned (series-resonant) topologies. In series mode, it forms part of the signal path between RF source and load, providing voltage-variable impedance with minimal insertion loss up to 1 GHz.
Is the SC79 package compatible with standard SMT reflow profiles?
Yes - the SC79 package uses matte tin (Sn) termination and is qualified for lead-free reflow per J-STD-020, with peak temperature support up to 260 °C. Its 0.7 mm body height and 0.35 mm lead pitch allow placement on fine-pitch PCBs using standard 0402-compatible stencil apertures and SPI inspection.
