Infineon Technologies BA892H6327XTSA1

Overview

BA892H6327XTSA1 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 use in TV/VTR tuner front-ends and mobile RF path selection.

For engineers reviewing the BA892H6327XTSA1 datasheet, BA892H6327XTSA1 pinout, BA892H6327XTSA1 application, or BA892H6327XTSA1 equivalent, key selection criteria include RF insertion loss (<0.5 dB at 1.8 GHz), 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 conduction (rf ≤ 0.7 Ω), while reverse bias provides high off-state isolation (>23 dB @ 100 MHz). Its 3 µm I-region width and 120 ns charge carrier lifetime support fast switching in multi-band antenna tuning circuits.

Designed for 50 Ω impedance-matched RF paths, it exhibits monotonic capacitance reduction from 1.4 pF (0 V) to 0.65 pF (1 V) and maintains >100 kΩ reverse parallel resistance up to 1 GHz - critical for minimizing harmonic distortion and intermodulation in VHF/UHF receivers.

FAQ

What is the maximum RF frequency range supported by BA892H6327XTSA1?

BA892H6327XTSA1 is characterized up to 2 GHz, with insertion loss and isolation data provided at 100 MHz, 470 MHz, 1 GHz, and 1.8 GHz. Measured IL remains ≤0.5 dB at 1.8 GHz (IF = 3 mA), confirming suitability for DVB-T/H and LTE band-switching applications within this range.

Does BA892H6327XTSA1 require external bias circuitry?

Yes - it requires a DC bias network to set forward/reverse states. Typical implementation uses a series resistor (e.g., 10 kΩ) from GPIO to anode, with cathode grounded. No integrated driver or level-shifting is included; bias voltage must stay within 0–3.3 V to avoid exceeding 100 mA IF rating.

How does the SC79 package affect thermal performance?

The SC79 package has R_thJS ≤ 120 K/W (junction-to-soldering-point), enabling 100 mW dissipation at ΔT = 12 °C above board temperature. Its small footprint (1.3 × 0.7 mm) limits copper pour area, so thermal relief pads and adjacent ground stitching vias are recommended for sustained 100 mA operation.

Is BA892H6327XTSA1 compatible with lead-free reflow profiles?

Yes - it is qualified for standard Pb-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. The device uses matte tin plating and passes MSL Level 1 testing, allowing unlimited floor life when stored at <30 °C/60% RH.
