Product details
Overview
BB914E6327HTSA1 from Infineon Technologies is a silicon hyperabrupt junction variable capacitance diode (varactor) in SOT23 package with common-cathode dual-diode configuration, designed for FM radio tuner front-ends. It delivers 42.5–45 pF capacitance at 2 V reverse bias, 17.6–19.75 pF at 8 V, and a minimum capacitance ratio CT₂/CT₈ of 2.28 at 1 MHz - enabling wide-band frequency tuning in automotive car radios.
For engineers reviewing the BB914E6327HTSA1 datasheet, BB914E6327HTSA1 pinout, BB914E6327HTSA1 application, or BB914E6327HTSA1 equivalent, key selection criteria include reverse voltage rating (18 V), series resistance (0.28 Ω typ. at 100 MHz), capacitance matching (≤1.5% ΔCT/CT), C–V linearity, and RoHS-compliant SOT23 packaging for space-constrained tuner modules.
Technical Context
The BB914E6327HTSA1 implements a monolithic dual-varactor structure with shared cathode, ensuring matched capacitance-voltage characteristics between both diodes - critical for differential tuning in FM IF and RF tank circuits. Its hyperabrupt doping profile yields a near-linear 1/C² vs. voltage response, supporting stable oscillator pulling and low-phase-noise VCO design.
Rated for operation from –55 °C to +125 °C and qualified per automotive-grade reliability standards, it sustains 20 V peak reverse voltage with ≤200 nA leakage at 16 V and 85 °C, enabling robust performance in 12 V vehicle electrical environments without external bias regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Capacitance @ 8 V | 17.6–19.75 pF - defines high-end tuning limit and achievable frequency span |
| Capacitance Ratio CT₂/CT₈ | 2.28–2.42 - determines usable tuning bandwidth without excessive varactor nonlinearity |
| Series Resistance rS | 0.28 Ω typ. @ 100 MHz - minimizes Q-factor degradation and insertion loss in resonant circuits |
| Reverse Voltage VR | 18 V DC max - supports direct connection to automotive 12 V supply with margin |
| Capacitance Matching ΔCT/CT | ≤1.5% @ 2 V & 8 V - ensures tracking accuracy in dual-diode differential tuning topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS16HV,215 (Nexperia) | Single anode, 100 V VR, 2.5 pF @ 0 V - lower capacitance, higher voltage rating | Designed for ESD protection + switching; not optimized for C–V linearity or matching | Use only where high-voltage transient immunity outweighs tuning precision requirements |
| BBY52-02W (Infineon) | Single varactor, 28 pF @ 2 V, CT₂/CT₈ = 2.1 - lower capacitance, reduced tuning ratio | Lacks dual-diode structure; requires external matching for differential tuning | Select when board area permits discrete matching or single-ended VCO architecture suffices |
Compared with BAS16HV and BBY52-02W, BB914E6327HTSA1 uniquely delivers monolithic dual-diode matching, FM-optimized C–V slope, and automotive-grade temperature stability - making it irreplaceable in cost-sensitive, space-constrained dual-tuned radio front-ends.

FAQ
What is the maximum recommended reverse voltage for continuous operation?
The BB914E6327HTSA1 has a DC reverse voltage rating (VR) of 18 V at 25 °C, with a peak reverse voltage (VRM) of 20 V for resistive loads ≥5 kΩ. Operation above 18 V DC risks irreversible junction breakdown, especially at elevated temperatures; design margin should maintain VR ≤15 V in automotive 12 V systems with ripple.
How does the common-cathode configuration impact PCB layout?
The shared cathode (Pin 2) must be routed as a low-inductance, low-resistance node - ideally connected directly to ground plane via multiple vias. Separating anode traces (Pins 1 and 3) prevents coupling; keep lengths equal and symmetric when used in differential VCO tanks to preserve matching.
Is BB914E6327HTSA1 suitable for 5G or Wi-Fi front-end tuning?
No - its 1 MHz–100 MHz characterization and C–V profile are optimized for FM broadcast (87.5–108 MHz) and DAB (174–230 MHz). At 2.4 GHz or 5 GHz, series resistance and parasitic inductance degrade Q-factor below usable levels; dedicated GaAs or SiGe varactors are required for those bands.
Does capacitance matching apply across temperature?
Capacitance matching (≤1.5% ΔCT/CT) is specified at TA = 25 °C. Over –55 °C to +125 °C, inter-diode tracking degrades to ≤3.5% due to thermal coefficient variation; system-level calibration or closed-loop PLL compensation is recommended for high-stability applications beyond 85 °C.
