Product details
Overview
BBY 53-02V E6327 from Infineon Technologies is a silicon hyperabrupt junction tuning diode (varactor) designed for voltage-controlled oscillator (VCO) frequency tuning in mobile communication transceivers. It delivers 5.3 pF capacitance at 1 V reverse bias, 2.4 pF at 3 V, a capacitance ratio CT₁/CT₃ of 2.2 (typ.), series resistance of 0.47 Ω at 1 GHz, and operates up to 125°C.
For engineers reviewing the BBY 53-02V E6327 datasheet, BBY 53-02V E6327 pinout, BBY 53-02V E6327 application in VCO tuning networks, or BBY 53-02V E6327 equivalent varactors for low-voltage RF front-ends, this page provides verified electrical behavior, package-specific layout data, thermal coefficient curves, and direct substitution guidance.
Technical Context
This hyperabrupt varactor exhibits a nonlinear C–V profile optimized for wide, monotonic capacitance swing across 1–3 V reverse bias-enabling fine-grained VCO frequency resolution in compact 2.8 × 1.2 mm SC79 packages. Its low 0.47 Ω series resistance at 1 GHz minimizes Q-factor degradation in UHF bands.
The device's temperature coefficient of capacitance (TCC) is –3.0 × 10⁻³ /°C at 1 V and –2.0 × 10⁻³ /°C at 3 V, enabling predictable drift compensation in temperature-sensitive PLL loops. Reverse leakage remains ≤10 nA at 4 V/25°C and ≤200 nA at 4 V/85°C-critical for stable VCO center-frequency hold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance @ 1 V | 5.3 pF max - sets upper bound of VCO tuning range in 800–2200 MHz bands |
| Capacitance @ 3 V | 2.4 pF typ - defines lower capacitance limit for high-frequency VCO operation |
| Capacitance Ratio CT₁/CT₃ | 2.2 typ - determines achievable frequency tuning bandwidth without harmonic distortion |
| Series Resistance rS | 0.47 Ω typ @ 1 GHz - directly limits Q-factor and phase noise floor in resonant tank |
| Reverse Voltage VR | 6 V max - establishes safe DC bias margin above typical 3–4.5 V VCO tuning rails |
| Reverse Leakage IR | ≤10 nA @ 4 V/25°C - ensures minimal DC current draw and long-term bias stability |
| TCC @ 1 V | –3.0 × 10⁻³ /°C - enables first-order temperature compensation in open-loop VCO designs |
Pinout & Package
BBY 53-02V E6327 is housed in the SC79 (SOD-523) leadless surface-mount package: 1.2 mm × 0.8 mm × 0.5 mm, cathode-marked top-side dot, single-anode/single-cathode configuration. No external leads; terminals are solder pads on bottom.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pad A) | RF AC signal node | Connected to VCO tank inductor; carries RF current with minimal loss due to low rS |
| Cathode (Pad K) | DC bias reference | Connected to tuning voltage source via high-impedance resistor; marked by white dot |

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BBY55-02V E6327 | Higher CT₁ = 6.8 pF max, CT₃ = 2.8 pF, rS = 0.55 Ω - wider tuning range but lower Q | Better for wideband VCOs (>20% span); less suitable for low-phase-noise narrowband designs | Select when tuning bandwidth >18% required and phase noise budget allows +1.5 dB degradation |
| SMV1232-011LF | CT₁ = 4.5 pF, CT₃ = 1.9 pF, rS = 0.35 Ω - lower rS but reduced ratio (2.1) | Superior for ultra-low-phase-noise 5G FR1 VCOs where Q dominates over ratio | Prefer when target Q > 120 at 3.5 GHz and tuning range ≤15% suffices |
Compared with BBY 53-02V E6327, BBY55-02V offers broader frequency coverage at the cost of Q, while SMV1232-011LF trades ratio for lower loss-making BBY 53-02V the balanced choice for mid-band cellular VCOs requiring both linearity and noise performance.

FAQ
What is the maximum recommended reverse bias voltage for BBY 53-02V E6327?
The absolute maximum reverse voltage is 6 V per datasheet ratings. For reliable long-term operation in VCO circuits, Infineon specifies 4 V as the maximum continuous DC bias-exceeding this risks accelerated junction degradation and increased leakage beyond 200 nA at 85°C.
Does BBY 53-02V E6327 require special PCB layout considerations?
Yes: the SC79 package demands symmetric thermal relief and 0.25 mm minimum solder mask dams between anode/cathode pads to prevent bridging. Ground plane clearance must be ≥0.3 mm around both pads to avoid parasitic capacitance shifts exceeding ±0.2 pF.
How does temperature affect capacitance stability in BBY 53-02V E6327?
At 1 V bias, capacitance changes –3.75% from –40°C to +85°C; at 3 V, it changes –2.25%. The device's TCC is –3.0 × 10⁻³ /°C at 1 V and –2.0 × 10⁻³ /°C at 3 V-values confirmed by curve-fit data in the official application note AN2011-06.
Can BBY 53-02V E6327 be used in DC blocking applications?
No-it is not rated for forward conduction or DC current handling. With only 20 mA absolute maximum forward current and no specified IF–VF curve, its junction is optimized for reverse-biased capacitive operation only. Use dedicated RF blocking diodes like BAR63 series for DC isolation.
