Infineon Technologies BA 892-02V E6327

Overview

BA892-02V E6327 from Infineon Technologies is a silicon RF switching diode in SC79 package, configured as a single anode-cathode junction for high-frequency band switching. 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 - enabling compact tuner front-ends in TV/VTR and mobile RF modules.

For engineers reviewing the BA892-02V E6327 datasheet, BA892-02V E6327 pinout, BA892-02V E6327 application, or BA892-02V E6327 equivalent, key selection criteria include its low RF insertion loss (≤0.1 dB @ 1.8 GHz, IF = 0.1 mA), AEC-Q101 qualification, RoHS-compliant leadless SC79 footprint, and verified performance in series-switched 50 Ω impedance paths.

Technical Context

This diode operates as a voltage-controlled RF series switch: forward bias enables low-loss signal conduction (rf ≤ 0.7 Ω), while reverse bias provides high isolation (>23 dB @ 100 MHz) via low capacitance (CT ≤ 1.4 pF) and high reverse parallel resistance (RP ≥ 100 kΩ @ 100 MHz). Its 120 ns charge carrier lifetime supports fast switching in tuner band-selection circuits.

Designed for DC–2 GHz operation, it exhibits monotonic CT vs. VR behavior (0.65 pF @ 1 V → 0.4 pF @ 3 V), stable rf vs. IF response (0.45 Ω typ. @ 3 mA), and thermal resistance RthJS ≤ 120 K/W - ensuring reliability under pulsed RF loads in automotive-qualified consumer tuners.

FAQ

What is the maximum RF frequency range supported by BA892-02V E6327?

BA892-02V E6327 is characterized up to 2 GHz in official documentation, with measured insertion loss ≤0.5 dB and isolation ≥5.5 dB at 1 GHz under specified bias conditions. Its 120 ns charge carrier lifetime and low capacitance support reliable switching in UHF TV (470–862 MHz) and LTE Band 1/3 (1.8–2.2 GHz) applications.

Does BA892-02V E6327 require external bias circuitry?

Yes - it requires a DC bias network to set forward/reverse states: typically a series resistor (1–10 kΩ) from control logic to anode, with cathode grounded. No integrated driver or level-shifting is provided; bias voltage must stay within 0–3 V to avoid exceeding VR rating or degrading CT performance.

How does the SC79 package affect PCB layout and thermal performance?

The SC79's 1.3 × 0.7 mm footprint and 0.35 mm height allow dense RF layout with minimal parasitic inductance. Its RthJS ≤ 120 K/W requires at least one thermal pad connected to internal ground plane; recommended land pattern matches Infineon's SCD80/SC79 standard - no solder mask defined on thermal pad for optimal heat transfer.

Is BA892-02V E6327 compatible with lead-free reflow profiles?

Yes - it is fully RoHS-compliant and qualified for JEDEC J-STD-020D MSLE Level 1 (260 °C peak, 60 sec max). The SC79 package withstands standard SAC305 reflow without delamination or parameter shift; post-reflow VF and CT remain within datasheet limits when cooled per recommended ramp rates.
