Product details
Overview
BB565 E7902 from NXP Semiconductors is a silicon hyperabrupt junction varactor diode optimized for UHF-TV tuner applications, featuring 18.5–21.5 pF capacitance at 1 V, 1.8–2.2 pF at 28 V, 9–11:1 capacitance ratio (CT₁/CT₂₈), and 0.6 Ω series resistance at 470 MHz. It operates from –55 °C to +150 °C in an SC79 package with cathode marking.
For engineers reviewing the BB565 E7902 datasheet, BB565 E7902 pinout, BB565 E7902 application, or BB565 E7902 equivalent, this part supports high-frequency tuning circuits requiring precise voltage-controlled capacitance, low RF loss, tight capacitance matching across production lots, and AEC-Q101 qualification for automotive tuner modules.
Technical Context
The BB565 E7902 implements a hyperabrupt doping profile to deliver a near-linear C–V characteristic slope in the 1–28 V range, enabling stable frequency tracking in PLL-based UHF synthesizers. Its 0.6 nH series inductance and 0.6 Ω series resistance minimize Q degradation above 470 MHz.
Capacitance matching is guaranteed via "in-line" assembly of 4-diode sequences (±0.5% typical ∆CT/CT), supporting multi-band tuner front-ends where inter-device tracking directly impacts channel selectivity and image rejection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance @ 1 V | 18.5–21.5 pF - sets low-end tuning range for UHF band (470–862 MHz) oscillator tanks |
| Capacitance @ 28 V | 1.8–2.2 pF - defines high-frequency limit and tuning bandwidth |
| Capacitance Ratio CT₁/CT₂₈ | 9–11:1 - enables ≥100 MHz continuous tuning span in single-VCO designs |
| Series Resistance @ 470 MHz | 0.6 Ω typ. - maintains Q > 100 at 700 MHz, critical for low-phase-noise local oscillators |
| Reverse Voltage Rating | 30 V DC / 35 V peak - supports standard tuner bias rails with margin against transient spikes |
| Operating Temperature | –55 °C to +150 °C - qualified for under-hood automotive tuner modules per AEC-Q101 |
| Capacitance Matching (∆CT/CT) | ±0.5% typ. over 4-diode sequence - ensures consistent tracking across dual-conversion IF stages |
Pinout & Package
BB565 E7902 is housed in the SC79 (SOD-523) surface-mount package: 1.2 mm × 0.8 mm × 0.55 mm body, cathode marked with laser-etched bar, single-diode configuration, 2 mm tape pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | RF signal reference node | Connected to ground or AC-coupled VCO tank in reverse-biased tuning configuration |
| Cathode | Control voltage input | Accepts 1–28 V tuning voltage; polarity must be observed to maintain reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Hyperabrupt junction profile | Delivers linearized C–V slope for predictable VCO gain (MHz/V) across full tuning range |
| In-line 4-diode matching | Guarantees ≤ ±0.5% capacitance deviation within sequence - eliminates manual binning in tuner module assembly |
| AEC-Q101 qualification | Validated for automotive temperature cycling, HTRB, and ESD (HBM ≥ 2 kV) - suitable for OEM infotainment tuners |
| Low 0.6 nH package inductance | Preserves self-resonant frequency > 3 GHz - avoids parasitic resonance in 700 MHz VCO tanks |
Applications
| UHF TV Tuner Front-End | Automotive Digital Radio (DAB/DAB+) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BB565-02V | Identical electrical specs; differs only in date-code marking format (E7902 vs. -02V suffix) | No functional difference; same SC79 package and AEC-Q101 qualification | Select BB565-02V if legacy BOM references that suffix; E7902 is current production marking |
| BB545 | Lower capacitance (13.2–16.4 pF @ 1 V), higher CT₁/CT₂₈ ratio (10–12:1), SOD323 package | Suitable for VHF/UHF hybrid tuners needing wider ratio but less absolute C; larger footprint | Choose BB545 only when design requires >11:1 ratio and can accommodate SOD323 size and lower C |
Compared with BB565-02V, E7902 offers identical performance in the same SC79 package, while BB545 trades absolute capacitance for higher ratio and uses a larger SOD323 body - making E7902 optimal for space-constrained UHF-only tuner designs demanding tight matching and low Rs.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The BB565 E7902 has a DC reverse voltage rating of 30 V at 25 °C, with a peak reverse voltage limit of 35 V. Operation above 30 V reduces reliability and accelerates degradation, especially above 85 °C. Derating to 25 V is advised for 150 °C ambient use.
Does BB565 E7902 require external biasing components for basic tuning function?
No external biasing components are required beyond a clean DC tuning voltage source (1–28 V) and AC coupling capacitor. The diode operates in reverse bias only; no series resistor or decoupling is mandated for standard VCO tank integration, though local 100 nF ceramic bypassing is recommended near the cathode pad.
How does the SC79 package compare to SOD323 in thermal performance?
The SC79 package (0.55 mm height) offers lower thermal resistance than SOD323 (0.9 mm height) due to shorter thermal path and smaller die attach area. Measured junction-to-ambient RθJA is ~320 K/W for SC79 versus ~380 K/W for SOD323 under identical PCB layout, enabling higher power handling in thermally dense tuner modules.
Is BB565 E7902 compatible with lead-free reflow profiles?
Yes - BB565 E7902 is RoHS-compliant and qualified for standard lead-free reflow (J-STD-020, peak 260 °C, 20–40 sec). The SC79 package withstands three reflow cycles without parameter shift or delamination, verified per AEC-Q101 stress testing protocols.
