Product details
Overview
BB 664-02V E7902 from Infineon Technologies is a silicon hyperabrupt junction variable capacitance diode (varactor) designed for VHF TV tuner frequency synthesis and RF voltage-controlled oscillator (VCO) tuning circuits. It delivers a capacitance range of 2.4–44.5 pF at 1 MHz, 17.8:1 capacitance ratio (VR = 1 V / 28 V), 0.6 nH series inductance, 0.75 Ω series resistance at 470 MHz, and operates from –55 °C to +150 °C.
For engineers reviewing the BB 664-02V E7902 datasheet, BB 664-02V E7902 pinout, BB 664-02V E7902 application, or BB 664-02V E7902 equivalent, key selection criteria include tunable capacitance linearity, low RF loss at VHF/UHF, thermal stability over automotive temperature ranges, and RoHS-compliant SC79 package compatibility with high-density RF layouts.
Technical Context
This varactor uses a hyperabrupt doping profile to achieve high capacitance ratio and near-linear C–V response in the 1–28 V tuning range-critical for stable VCO gain (MHz/V) and reduced phase noise in analog TV and FM radio front-ends. Its SC79 package minimizes parasitic inductance (0.6 nH) and enables direct integration into impedance-matched microstrip tuning networks.
The device meets AEC-Q101 stress testing for automotive applications and exhibits ±2% capacitance matching across 7-diode sequences-enabling precise multi-stage filter or oscillator bank calibration without individual trimming. Reverse leakage remains ≤100 nA at 85 °C, supporting reliable long-term bias stability in sealed tuner modules.
Key Specifications

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 | Lower capacitance ratio (12.6:1), higher series resistance (1.2 Ω), SCD80 package (0.7 nH LS) | Less suitable for wideband VCOs requiring low phase noise; better for narrow-range IF filters | Select when cost sensitivity outweighs VCO linearity needs and board space permits larger SCD80 footprint |
| SMV1232-011 | Higher max capacitance (55 pF), tighter matching (±1%), but no AEC-Q101 qualification; SOD-523 package | Not approved for automotive use; requires additional reliability validation for industrial deployments | Prefer for consumer-grade IoT transceivers where qualification overhead is prohibitive and tighter matching is critical |
Compared with BBY52-02W and SMV1232-011, BB 664-02V E7902 uniquely balances automotive qualification, VHF-optimized C–V linearity, and SC79 layout efficiency-making it the default choice for AEC-Q101-compliant tuner modules requiring ≤2% unit-to-unit capacitance variance.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The BB 664-02V E7902 has a rated DC reverse voltage (VR) of 30 V and a peak reverse voltage (VRM) of 35 V. For continuous bias in VCO tuning networks, operation up to 28 V is specified in the capacitance ratio test condition and ensures long-term reliability without accelerated aging or leakage increase.
Does this varactor require external temperature compensation in VHF designs?
No external compensation is required: the device's temperature coefficient of capacitance (TCC) is characterized from –55 °C to +150 °C and remains within ±100 ppm/°C across its operating range. Its AEC-Q101 qualification confirms stable C–V behavior under thermal cycling, eliminating need for thermistor-based bias correction in automotive tuners.
Can BB 664-02V E7902 be used in 5G sub-6 GHz front-ends?
It is not recommended for 3.5 GHz or 5 GHz bands: while its self-resonant frequency exceeds 2 GHz, series resistance (0.75 Ω) and package parasitics cause Q-factor erosion above 1.5 GHz. For sub-6 GHz, Infineon's BAV99-02V or SMV2023 variants offer lower rS and optimized SOD-723 footprints.
How is capacitance matching verified across production lots?
Matching is validated using "in-line" assembly: seven diodes are processed consecutively on the same wafer segment and tested at VR = 1–28 V, 1 MHz. Measured ∆CT/CT ≤2% triggers lot release; outliers are discarded before packaging. Full traceability to wafer lot and test date is provided in Aetrix's certificate of conformance.
