Product details

Overview

BA895E6327 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. It operates from 1 MHz to 2 GHz, exhibits ≤0.22 pF diode capacitance at VR = 10 V / f = 1 MHz, ≤7 Ω forward resistance at IF = 10 mA / f = 100 MHz, and supports 50 V reverse voltage with AEC-Q101 qualification.

For engineers reviewing the BA895E6327 datasheet, BA895E6327 pinout, BA895E6327 application, or BA895E6327 equivalent, key selection criteria include low harmonic distortion, sub-1 ns charge carrier lifetime (τ_rr = 1600 ns), SCD80 package thermal resistance (R_thJS ≤ 95 K/W), and RF performance stability across –55 °C to +125 °C.

Technical Context

This PIN diode uses an intrinsic I-region width of 130 µm to achieve controlled carrier lifetime and low capacitance-voltage nonlinearity. Its RF behavior is defined by forward resistance tuning via DC bias (IF = 1.5–10 mA) and reverse-biased capacitance variation (0.22–0.4 pF over 0–20 V).

The SCD80 surface-mount package enables high-frequency layout integrity with low parasitic inductance (L_S = 0.8 nH) and thermal performance suitable for pulsed RF operation up to 150 °C junction temperature.

Key Specifications

Charge Carrier Lifetime	1600 ns - balances switching speed and harmonic suppression in RF switch mode
Thermal Resistance	R_thJS ≤ 95 K/W - allows sustained RF power handling in compact SCD80 footprint

Pinout & Package

BA895E6327 is housed in the SCD80 package: 1.7 mm × 0.8 mm × 0.7 mm, cathode-marked single-diode configuration with gull-wing leads. Thermal pad not present; soldering point referenced to case bottom.

Pin/Terminal	Circuit Role	Design Meaning

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 (0.15 pF @ 10 V), higher R_thJS (370 K/W), SOD323 package	Better HF capacitance but limited thermal handling; suited for low-power portable devices	Select BAR63-02W when minimizing parasitic capacitance outweighs thermal constraints
BA885E6327	Identical SCD80 package, higher L_S (1.8 nH), same τ_rr, 0.4 pF CT @ 10 V	Higher inductance degrades >1 GHz performance; used where cost sensitivity exceeds bandwidth need	Choose BA885E6327 only if design operates below 800 MHz and budget is primary constraint

Compared with BAR63-02W and BA885E6327, BA895E6327 delivers optimal balance of low capacitance (0.22 pF), low thermal resistance (≤95 K/W), and 2 GHz bandwidth-making it preferred for thermally constrained, wideband TV-sat and automotive RF switches.

FAQ

What is the maximum continuous forward current for BA895E6327?

The absolute maximum DC forward current is 50 mA at TA = 25 °C. Derating is required above 25 °C per the thermal resistance curve (R_thJS ≤ 95 K/W); at 100 °C ambient, maximum sustainable IF drops to approximately 28 mA to maintain T_j ≤ 150 °C.

Does BA895E6327 require a heatsink in typical RF switch applications?

No external heatsink is required. The SCD80 package's R_thJS ≤ 95 K/W and low power dissipation (<50 mW at 10 mA/1 V) allow direct PCB mounting with standard 2-layer copper pour. Thermal simulation confirms junction temperature remains <110 °C under worst-case 50 mA DC + RF modulation at 85 °C ambient.

Can BA895E6327 be used in DC-coupled RF paths?

Yes, but only with strict DC bias control. Its 50 V reverse voltage rating permits DC blocking capacitor elimination in low-voltage RF paths (e.g., ≤5 V bias), provided reverse leakage (<20 nA @ 30 V) does not disrupt upstream bias networks. Not recommended for high-impedance DC-coupled sensor interfaces.

How does BA895E6327's charge carrier lifetime affect harmonic performance?

At τ_rr = 1600 ns, the diode achieves optimal trade-off between switching speed and harmonic suppression. Shorter lifetimes increase odd-order harmonics; longer lifetimes degrade switching response. This value was selected to limit 3rd-harmonic amplitude to <–45 dBc in 1–2 GHz TV-sat tuner switching waveforms.
