Infineon Technologies BA89202LE6327

Overview

BA89202LE6327 from Infineon Technologies is a silicon RF switching diode in SC79 package, configured as a single anode-cathode junction for series-mode band switching in TV/VTR tuners and mobile RF front-ends. It delivers 0.45 Ω typical forward resistance at 3 mA/100 MHz, 0.65–1.4 pF capacitance (1 MHz–100 MHz), and 23.5 dB isolation at 100 MHz under 0 V bias.

For engineers reviewing the BA89202LE6327 datasheet, BA89202LE6327 pinout, BA89202LE6327 application, or BA89202LE6327 equivalent, key selection criteria include RF insertion loss (≤0.1 dB at 1.8 GHz/0.1 mA), reverse voltage rating (35 V), junction temperature limit (150 °C), and AEC-Q101 qualification for automotive tuner modules.

Technical Context

This diode operates as a voltage-controlled RF series switch: forward bias enables low-loss signal path conduction (rf ≤ 0.45 Ω), while reverse bias provides high isolation (ISO ≥ 23.5 dB @ 100 MHz) via depletion-layer capacitance control. Its 0.65 pF typ. CT at 1 V reverse bias and 100 kΩ typ. RP at 100 MHz support stable impedance matching in 50 Ω systems.

Designed for high-frequency switching up to 1.8 GHz, it exhibits 120 ns charge carrier lifetime (τ_rr) and 3 µm I-region width-enabling fast turn-on/off transitions with minimal distortion in tuner IF/RF signal routing applications.

FAQ

What is the maximum RF frequency supported by BA89202LE6327?

BA89202LE6327 is characterized up to 1.8 GHz with verified insertion loss (≤0.1 dB at 0.1 mA) and isolation (≥5.5 dB at 1 GHz). Its 120 ns charge carrier lifetime and 3 µm I-region width support stable operation in LTE Band 3/7/40 front-ends without significant harmonic generation.

Does BA89202LE6327 require external bias circuitry?

Yes-BA89202LE6327 requires a DC bias network to switch between forward conduction (typically 0.5–3 mA) and reverse isolation states. Typical implementation uses a series resistor (1–10 kΩ) and blocking capacitor (100 pF) to separate RF and DC paths while maintaining 50 Ω impedance match.

Is BA89202LE6327 compatible with lead-free reflow soldering?

Yes-BA89202LE6327 is Pb-free and RoHS-compliant, qualified for standard lead-free reflow profiles (peak temperature 260 °C, 10-second dwell). Its SC79 package withstands thermal cycling per J-STD-020 without delamination or solder joint failure.

How does BA89202LE6327 differ from BA892-02L?

BA89202LE6327 is the tape-and-reel packaged variant (E6327 suffix) of BA892-02L, sharing identical electrical specs, SC79 package, and AEC-Q101 qualification. The "E6327" denotes Infineon's standard 8,000-piece 180 mm reel format with 2 mm pitch-optimized for automated SMT placement.
