Product details
Overview
BBY 57-02W E6127 from Infineon Technologies is a hyperabrupt silicon tuning diode optimized for voltage-controlled oscillators (VCOs) in mobile communications equipment, featuring 18.6 pF capacitance at 1 V, 2.45 capacitance ratio (CT₁/CT₃), 0.3 Ω series resistance at 470 MHz, and operation from –55 °C to +125 °C in SC79 package.
For engineers reviewing the BBY 57-02W E6127 datasheet, BBY 57-02W E6127 pinout, BBY 57-02W E6127 application in VCO tuning or TCXO/VCXO control circuits, or BBY 57-02W E6127 equivalent for low-voltage hyperabrupt varactor selection, this page delivers verified electrical, thermal, and packaging specifications aligned with AEC-Q101 qualification.
Technical Context
This diode implements a hyperabrupt junction profile to deliver near-linear C–V response over 1–4 V reverse bias, enabling stable frequency pulling in compact RF synthesizers. Its low series resistance (≤0.3 Ω) and high Q-factor support efficient tuning up to UHF frequencies without significant insertion loss.
The device operates as a voltage-variable capacitor with cathode-common configuration, requiring no forward bias in normal use. Temperature coefficient of capacitance ranges from –3×10⁻² to –4×10⁻² /°C across 1–4 V, ensuring predictable drift compensation in temperature-stable oscillator designs.

FAQ
What is the cathode marking convention for BBY 57-02W E6127?
The cathode is marked by a visible bar on the top surface of the SC79 package, positioned adjacent to Pin 2. This matches Infineon's standard SOD-523 marking layout, confirmed in Package Outline Drawing 2007-04-20 Sheet 4. No laser code or alphanumeric marking is used-only the cathode bar serves as polarity indicator.
Does BBY 57-02W E6127 support DC blocking in RF signal paths?
No-BBY 57-02W E6127 is designed exclusively as a reverse-biased varactor diode and must not be forward-biased. It lacks DC current handling capability beyond 20 mA absolute max, and its hyperabrupt junction is not rated for rectification. Use dedicated RF blocking capacitors or Schottky diodes for DC isolation.
How does temperature affect capacitance stability in BBY 57-02W E6127?
At 1 V bias, capacitance drift is bounded by ±4% from –55 °C to +125 °C, per normalized C(TA)/C(25°C) curve in Sheet 3. The temperature coefficient ranges from –3×10⁻² to –4×10⁻² /°C depending on bias voltage, enabling predictable compensation in TCXO designs when paired with NPO or NP0 capacitors.
Is BBY 57-02W E6127 compatible with lead-free reflow soldering?
Yes-BBY 57-02W E6127 is Pb-free and RoHS-compliant, qualified for peak reflow temperatures up to 260 °C per J-STD-020. Its SC79 package withstands standard lead-free thermal profiles without delamination or parametric shift, and the die attach and metallization are fully compatible with SAC305 solder paste.
