Product details

Overview

BA892H6770XTSA1 from Infineon Technologies is a silicon RF switching diode in SC79 package, configured as a single anode-cathode junction for high-frequency band switching in TV/VTR tuners and mobile RF front-ends. It delivers typ. 0.45 Ω 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 reverse bias.

For engineers reviewing the BA892H6770XTSA1 datasheet, BA892H6770XTSA1 pinout, BA892H6770XTSA1 application, or BA892H6770XTSA1 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 in impedance-matched 50 Ω signal paths. Its low charge carrier lifetime (120 ns) and narrow I-region width (3 µm) enable fast switching with minimal distortion in UHF bands up to 1 GHz.

The device exhibits nonlinear capacitance vs. reverse voltage (0.4–1.2 pF over 0–20 V at 1 MHz) and frequency-dependent forward resistance (0.36 Ω at 10 mA/100 MHz), supporting precise tuning in VCO and antenna diversity circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
Reverse Voltage (VR)	35 V - supports DC blocking and RF switching in tuner stages up to 30 V bias rails
Forward Resistance (rf)	0.45 Ω typ. @ 3 mA, 100 MHz - minimizes insertion loss in series-switched RF paths
Diode Capacitance (CT)	0.65 pF typ. @ VR = 1 V, 1 MHz - enables fine-tuning of resonant circuits in VHF/UHF filters
Isolation (ISO)	23.5 dB @ VR = 0 V, 100 MHz - provides effective signal path separation in antenna switching
Junction Temperature (TJ)	150 °C - ensures reliability in thermally constrained mobile and automotive tuner modules
AEC-Q101 Qualified	Yes - validated for automotive-grade RF tuner applications per stress test requirements

Pinout & Package

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar RF switching diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAR63-02W	Lower CT (0.35 pF typ. @ 1 V), higher IR (50 nA max), same SC79 package	Better for high-isolation VHF filtering; less suitable for low-loss 1.8 GHz mobile switching	Prefer BAR63-02W when capacitance <0.4 pF is required for >400 MHz filter sharpness
BAV99	Dual-series configuration, higher VF (1.25 V max), 70 V VR, SOT-23 package	Designed for general-purpose high-speed switching, not optimized for RF insertion loss or capacitance linearity	Select BAV99 only for non-RF logic-level or ESD-clamp roles where RF performance is secondary

Compared with BAR63-02W and BAV99, BA892H6770XTSA1 uniquely balances sub-0.5 Ω RF resistance, sub-1 pF capacitance, and AEC-Q101 qualification-making it optimal for automotive and mobile tuner band-switching where both loss and reliability are critical.

FAQ

What is the maximum RF frequency at which BA892H6770XTSA1 maintains usable insertion loss?

BA892H6770XTSA1 achieves ≤0.5 dB insertion loss up to 1.8 GHz at 3 mA forward bias, as confirmed by S-parameter measurements in series configuration (Z₀ = 50 Ω). Performance degrades above 2 GHz due to rising forward resistance and parasitic effects; it is not characterized beyond 3 GHz.

Can BA892H6770XTSA1 be used in varactor mode for voltage-controlled tuning?

Yes - its capacitance varies from 1.4 pF (0 V) to 0.4 pF (20 V) at 1 MHz, enabling use as a tuning diode in VHF/UHF LC oscillators and filters. However, its Q-factor drops above 100 MHz due to 100 kΩ reverse parallel resistance, limiting effectiveness in high-frequency VCOs.

Is thermal derating required when operating at 125 °C ambient?

Yes - at T_A = 125 °C, forward current must be limited to ≤50 mA to maintain T_J ≤ 150 °C, given R_thJS ≤ 120 K/W. Derating curves in Infineon Application Note AN2011-07 show 60% IF reduction versus 25 °C rating.

Does BA892H6770XTSA1 support bidirectional RF signal routing?

No - it is a unidirectional silicon PIN diode optimized for series-switch operation with anode-to-RF-source orientation. Reverse bias blocks RF in one direction only; bidirectional routing requires dual-diode configurations or SPDT switch ICs.
