Product details

Overview

BA892 E6433 from ROHM Semiconductor is a silicon RF switching diode in SC79 package, configured as a single anode-cathode junction for high-frequency signal path control. 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 band switching in TV/VTR tuners and mobile RF front-ends.

For engineers reviewing the BA892 E6433 datasheet, BA892 E6433 pinout, BA892 E6433 application, or BA892 E6433 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 RoHS-compliant leadless packaging for compact tuner modules.

Technical Context

The BA892 E6433 operates as a passive series-switching diode in RF signal routing paths, leveraging low I-region width (3 µm) and fast charge carrier lifetime (120 ns) to support high-speed switching up to 1.8 GHz. Its SCD80/SC79 footprint compatibility enables drop-in replacement in space-constrained tuner designs.

AC performance is defined by voltage-dependent capacitance (0.65 pF @ 1 V, 0.85 pF @ 3 V, 1.1 pF @ 0 V/100 MHz) and frequency-dependent forward resistance (0.45 Ω @ 3 mA/100 MHz, 0.36 Ω @ 10 mA/100 MHz), optimized for minimal signal distortion in VHF/UHF band selection circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
Reverse Voltage	35 V - supports biasing in tuner IF/RF stages without breakdown under transient surge conditions.
Forward Resistance	0.45 Ω typ. @ 3 mA/100 MHz - ensures low insertion loss (<0.5 dB at 1.8 GHz) in series-switched antenna paths.
Diode Capacitance	0.65–1.4 pF (1 MHz–100 MHz) - enables broadband matching across VHF to UHF bands with minimal detuning.
Isolation	23.5 dB @ 100 MHz - provides sufficient off-state attenuation to prevent inter-band coupling in multi-channel tuners.
Junction Temp	150 °C - allows operation in thermally dense tuner modules without derating in automotive or set-top box environments.
Package	SC79 - 1.3 × 0.7 mm surface-mount outline with cathode marking, compatible with automated placement and reflow.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BA892-02L	Same die, TSLP-2-1 package (1.0 × 0.6 mm); 0.4 nH LS vs SC79's 0.6 nH	Higher self-resonant frequency due to lower parasitic inductance - better for >1 GHz use	Select when operating above 1.5 GHz or requiring tighter layout tolerance
BAR63-02W	0.35 Ω R_f typ., 0.25 pF C_T @ 1 V, but only 20 V VR rating	Superior HF performance but lower voltage margin - unsuitable for tuner surge conditions	Prefer for 2.4 GHz ISM apps where voltage stress is low and loss is critical

Compared with BA892-02L and BAR63-02W, BA892 E6433 balances 35 V robustness, 0.45 Ω conduction loss, and SC79 manufacturability - making it optimal for cost-sensitive, thermally constrained TV tuner designs requiring AEC-Q101 validation.

FAQ

What is the maximum RF frequency supported by BA892 E6433?

BA892 E6433 is characterized up to 1.8 GHz with verified insertion loss (<0.5 dB at 10 mA bias) and isolation (>5.5 dB at 1 GHz). Its 0.65–1.4 pF capacitance and 0.45 Ω forward resistance support stable operation through UHF band, though optimal performance occurs below 1.2 GHz where S-parameters remain tightly specified.

Does BA892 E6433 require external bias circuitry?

Yes - BA892 E6433 is a passive PIN diode requiring DC bias to switch between low-resistance (forward-biased) and high-isolation (reverse-biased) states. Typical bias is +3 V via series resistor for on-state and 0 V or negative voltage for off-state; no integrated driver or logic interface is included.

Is BA892 E6433 compatible with lead-free reflow soldering?

Yes - BA892 E6433 uses Pb-free terminations and is qualified for standard lead-free reflow profiles (JEDEC J-STD-020, peak 260 °C). The SC79 package withstands thermal cycling without delamination, and its 0.4 mm profile ensures uniform heating during convection reflow.

How does BA892 E6433 differ from BA592?

BA892 E6433 and BA592 share identical electrical specs but differ in package: BA592 uses SOD323 (1.7 × 1.25 mm), while BA892 E6433 uses SC79 (1.3 × 0.7 mm). SC79 offers 30% smaller footprint and lower parasitic inductance (0.6 nH vs SOD323's 1.8 nH), improving high-frequency response in dense tuner layouts.
