Product details
Overview
BB 833 E6433 from Infineon Technologies is a silicon tuning diode (varactor) in SOD323 package, designed for VHF/UHF frequency tuning in satellite TV tuners up to 2.5 GHz. It delivers a typical capacitance of 9.3 pF at 1 V reverse bias, 0.75 pF at 28 V, with a capacitance ratio CT₁/CT₂₈ ≥ 11 and series resistance rₛ = 1.8 Ω at 470 MHz.
For engineers reviewing the BB 833 E6433 datasheet, BB 833 E6433 pinout, BB 833 E6433 application, or BB 833 E6433 equivalent, key selection criteria include capacitance vs. voltage curve linearity, temperature coefficient of capacitance (TCc), reverse leakage at elevated temperature, and matching tolerance (∆CT/CT ≤ 3%) for differential tuner architectures.
Technical Context
This varactor operates as a voltage-controlled capacitor in resonant LC tank circuits, where reverse bias voltage directly modulates junction capacitance. Its SOD323 package enables compact RF layout with low parasitic inductance (LS = 1.8 nH), critical for stable tuning above 1 GHz.
The device exhibits a negative temperature coefficient of capacitance (TCc ≈ −4×10⁻⁴ /°C at VR = 1 V), requiring compensation in wide-temperature-range tuner designs. Capacitance matching across paired devices is specified to ±3% at both 1 V and 28 V, supporting balanced front-end architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance at VR = 1 V | 9.3 pF typical - sets low-frequency end of tuning range in LC oscillator |
| Capacitance at VR = 28 V | 0.75 pF typical - defines high-frequency limit and tuning bandwidth |
| Capacitance ratio CT₁/CT₂₈ | ≥11 - enables >1.5:1 frequency ratio in VCO or filter bank design |
| Series resistance rₛ | 1.8 Ω at 470 MHz - limits Q-factor and phase noise in resonant circuits |
| Reverse leakage IR | ≤500 nA at VR = 30 V, TA = 85 °C - ensures stable bias point under thermal stress |
| Max reverse voltage VR | 30 V DC - defines absolute tuning voltage ceiling without breakdown risk |
Pinout & Package
SOD323 surface-mount package: 2-terminal anode/cathode configuration, 1.7 mm × 1.25 mm footprint, 0.95 mm height, matte tin (Pb-free) terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (marked side) | Forward current entry / reference node | Connected to ground or bias network; polarity must be observed to avoid forward conduction |
| Cathode (unmarked side) | Reverse-biased terminal / tuning node | DC control voltage applied here; AC signal path couples through junction capacitance |
Key Features
| Feature | Design Value |
|---|---|
| Extended frequency range | Validated operation up to 2.5 GHz - supports DVB-S2X and next-gen satellite tuner bands |
| High capacitance ratio | CT₁/CT₂₈ ≥ 11 - enables wider frequency coverage without switching capacitors |
| Tight capacitance matching | ∆CT/CT ≤ 3% - allows matched-pair use in differential VCOs and image-reject filters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54C (Diodes Inc.) | Lower CT ratio (≈4.5), higher rₛ (≈3.5 Ω), SOT-23 package | Not suitable for >1 GHz tuning; limited to AM/FM radio IF stages | Select only for cost-sensitive sub-500 MHz applications where Q and tuning range are secondary |
| SMV1232-011 (Skyworks) | Higher CT₁ (12.5 pF), tighter matching (±1.5%), but VR max = 15 V | Requires redesign of bias network; unsuitable for 28 V tuner rails | Prefer when ultra-low phase noise is required and supply voltage is constrained to ≤15 V |
Compared with BAT54C and SMV1232-011, BB 833 E6433 uniquely balances high-voltage operation (30 V), GHz-range usability, and production-grade matching-making it optimal for satellite tuner OEMs needing drop-in reliability without bias redesign.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The absolute maximum DC reverse voltage is 30 V at TA = 25 °C. At elevated temperatures (e.g., 85 °C), derating is advised: sustained operation above 25 V requires thermal validation. Peak reverse voltage (VRM) is rated at 35 V for transient conditions only, with R ≥ 5 kΩ limiting current.
How does capacitance change with temperature at VR = 1 V?
At VR = 1 V, the temperature coefficient of capacitance (TCc) is approximately −4×10⁻⁴ /°C, meaning capacitance decreases by ~0.04% per °C rise. This is documented in Figure 3 of the 2011 datasheet and confirmed via on-wafer characterization at multiple temperatures.
Is BB 833 E6433 suitable for use in life-support equipment?
No. Per Infineon's legal disclaimer (Edition 2009-11-16), BB 833 E6433 is not approved for use in life-support devices or systems. Its qualification excludes implantable or safety-critical medical applications where failure could endanger human life.
Can this diode be used in series or parallel configurations?
Parallel use is supported for increased effective capacitance, provided matching tolerances (∆CT/CT ≤ 3%) are maintained. Series connection is not recommended: unequal voltage division risks forward conduction in one device, especially under RF modulation or thermal gradient.
