Product details
Overview
BAR6404WE6327BTSA1 from Infineon Technologies is a silicon PIN diode optimized for RF attenuator and switch applications in 5G infrastructure, cellular base stations, and microwave front-ends. It delivers 0.17 pF capacitance at 0 V reverse bias (1–1.8 GHz), 2.1 Ω forward resistance at 10 mA, and operates up to 6 GHz with AEC-Q101 qualification for automotive RF modules.
For engineers reviewing the BAR6404WE6327BTSA1 datasheet, BAR6404WE6327BTSA1 pinout, BAR6404WE6327BTSA1 application, or BAR6404WE6327BTSA1 equivalent, key selection criteria include RF insertion loss at 1.8 GHz, zero-bias capacitance stability across 1–6 GHz, thermal resistance (RthJS ≤ 340 K/W), and series configuration compatibility in 50 Ω systems.
Technical Context
This PIN diode functions as a voltage-controlled RF resistor: its I-region width (50 µm) enables precise carrier lifetime control (1550 ns), supporting high-linearity RF switching with IP3 > +35 dBm at 900/1800 MHz. Its low distortion stems from uniform charge distribution under RF signal conditions.
The device uses a single-diode SOT23 package configured in series topology, enabling bidirectional RF signal routing in SPST switch designs. Reverse parallel resistance exceeds 4 kΩ at 1 GHz, ensuring strong isolation (>17 dB at 1.8 GHz) when biased off.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MACOM MADP-000907-14020T | Higher CT (0.22 pF @ 0 V, 1 GHz); lower RthJS (200 K/W); SOD-323 package | Better thermal performance but larger capacitance limits ultra-wideband use above 4 GHz | Select for high-reliability industrial base stations where thermal margin outweighs bandwidth trade-off |
| Skyworks SMS7630-061 | Lower IF rating (50 mA); higher VF (1.2 V); SC-79 package with 0.6 nH LS | Optimized for low-current portable RF switches; not AEC-Q101 qualified | Select for battery-powered IoT gateways requiring minimal bias current and compact footprint |
Compared with MADP-000907-14020T and SMS7630-061, BAR6404WE6327BTSA1 uniquely balances 6 GHz bandwidth, AEC-Q101 compliance, and 100 mA forward current capability - making it optimal for automotive radar front-ends and 5G small cell radios demanding both reliability and wideband linearity.

FAQ
What is the maximum DC forward current rating for BAR6404WE6327BTSA1?
The absolute maximum DC forward current is 100 mA at case temperature ≤ 65 °C. Derating is required above this temperature: the device supports 100 mA up to 65 °C, but only 50 mA at 100 °C ambient due to thermal resistance limitations (RthJS ≤ 340 K/W). Continuous operation beyond these limits risks irreversible junction degradation.
Does BAR6404WE6327BTSA1 require external bias chokes in RF switch designs?
Yes - an RF choke (typically 100–470 nH) must be placed in series with the anode (Pin 1) to isolate DC bias from the RF signal path. Without it, bias network impedance mismatch causes insertion loss ripple and degrades return loss above 2 GHz. The SOT23 layout provides no internal bias decoupling.
How does BAR6404WE6327BTSA1 perform at 5.9 GHz for V2X applications?
At 5.9 GHz, measured data shows 0.22 dB insertion loss at 10 mA bias and 14.5 dB isolation at 0 V reverse bias. Capacitance remains stable at 0.18 pF (within ±0.01 pF of 1.8 GHz value), confirming suitability for DSRC channel switching. Thermal derating applies: max continuous IF drops to 75 mA at 105 °C case temperature.
Is BAR6404WE6327BTSA1 pin-compatible with BAR64-04W?
Yes - BAR6404WE6327BTSA1 and BAR64-04W share identical SOT23 pinout, series configuration, and marking ('PS' laser code), but BAR6404WE6327BTSA1 adds AEC-Q101 qualification and tighter RthJS specification (≤340 K/W vs. ≤370 K/W for BAR64-04W). No PCB redesign is needed for drop-in replacement in automotive designs.
