Product details
Overview
BA595E6433HTMA1 from Infineon Technologies is a silicon PIN diode optimized as a current-controlled RF resistor for antenna switching and RF attenuation in TV-sat tuners, featuring 50 V reverse voltage rating, 50 mA forward current capability, 0.26 pF diode capacitance at 100 MHz (VR = 0 V), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BA595E6433HTMA1 datasheet, BA595E6433HTMA1 pinout, BA595E6433HTMA1 application, or BA595E6433HTMA1 equivalent, key selection criteria include RF insertion loss at 1 GHz, reverse parallel resistance >50 kΩ at 100 MHz, low harmonic distortion, SCD80 package thermal resistance ≤95 K/W, and junction temperature limit of 150°C.
Technical Context
This PIN diode operates by modulating its RF resistance via DC bias current-forward resistance drops from 40 Ω at 1.5 mA to 4.5 Ω at 10 mA (100 MHz), enabling precise analog attenuation. Its I-region width of 130 µm supports fast carrier lifetime (1600 ns) and low capacitance variation across 0–30 V reverse bias.
The device exhibits minimal nonlinear distortion due to symmetric charge carrier distribution, with measured harmonic suppression suitable for tuner front-end switching. Its SCD80 surface-mount package enables high-density RF layout while maintaining thermal performance up to 125°C ambient operation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PIN diode RF switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-02W | Lower CT (0.22 pF @ 100 MHz), higher IF rating (100 mA), SOD-323 package | Better suited for higher-frequency (>2 GHz) or higher-current switching where thermal margin is critical | Prefer BAR63-02W when board space allows SOD-323 and RF bandwidth exceeds 2.1 GHz |
| BA895 | Same SCD80 package, lower I-region width (0.8 nH LS), CT = 0.22 pF @ 100 MHz, τrr = 1600 ns | Optimized for faster switching speed in time-critical tuner AGC loops | Select BA895 when turn-on/turn-off timing <1.5 µs is required and 30 V VR suffices |
Compared with BAR63-02W and BA895, BA595E6433HTMA1 offers superior thermal resistance (≤95 K/W vs. ~150 K/W for BAR63-02W) and higher reverse voltage (50 V vs. 30 V for BA895), making it optimal for thermally constrained, high-isolation satellite tuner designs.

FAQ
What is the maximum RF frequency range supported by BA595E6433HTMA1?
BA595E6433HTMA1 is characterized for operation from 1 MHz to 2 GHz, with verified RF performance including diode capacitance, forward resistance, and reverse parallel resistance across this band. At 2 GHz, measured forward resistance remains ≤7 Ω (IF = 10 mA), supporting use in DVB-S2 tuners up to 2150 MHz.
Is BA595E6433HTMA1 suitable for reflow soldering per JEDEC J-STD-020?
Yes-BA595E6433HTMA1 uses a Pb-free (RoHS-compliant) SCD80 package qualified for standard SnPb and lead-free reflow profiles. Peak temperature tolerance is 260°C for 10 seconds, matching JEDEC J-STD-020D Level 1 requirements for moisture sensitivity.
How does the 130 µm I-region width affect switching behavior?
The 130 µm intrinsic region determines carrier lifetime (τrr = 1600 ns) and capacitance-voltage slope. It enables low capacitance (<0.4 pF) at zero bias while sustaining high reverse voltage (50 V); longer I-regions increase τrr but reduce VR, so this value balances speed, isolation, and breakdown margin.
Can BA595E6433HTMA1 replace BA885 in existing designs?
Yes-BA595E6433HTMA1 shares the SCD80 package, pinout, and electrical specifications with BA885 (same VF, CT, RP, and RthJS), but adds AEC-Q101 qualification and tighter IR specification (≤20 nA). No layout or bias circuit changes are needed for drop-in replacement in automotive or industrial tuner upgrades.
