Product details

Overview

BAR141E6327HTSA1 from Infineon Technologies is a silicon PIN diode optimized for RF switching and attenuation above 10 MHz, featuring 100 V reverse voltage rating, 140 mA forward current capability, and low 0.25 pF capacitance at 50 V bias - deployed in cellular front-end modules and antenna tuning circuits.

For engineers reviewing the BAR141E6327HTSA1 datasheet, BAR141E6327HTSA1 pinout, BAR141E6327HTSA1 application, or BAR141E6327HTSA1 equivalent, key selection criteria include zero-bias conductance (50–100 µS), reverse recovery time (700–1000 ns), I-region width (146 µm), and SOT143 package thermal resistance (≤340 K/W).

Technical Context

This PIN diode operates as a voltage-controlled RF resistor in series/shunt switch configurations, leveraging its linearized C_V vs. V_R curve and stable g_P across temperature. Its 146 µm intrinsic region enables predictable charge carrier lifetime (τ_rr = 700–1000 ns) under 10 mA forward / 6 mA reverse step conditions.

The device exhibits low distortion factor due to minimal harmonic generation in attenuator networks, validated by constant rf values (e.g., 5.5 Ω at 1 mA/100 MHz) and tight CT tolerance (0.2–0.5 pF) across 0–50 V bias - critical for broadband 3G/4G RF front-end linearity.

Key Specifications

Parameter	Value and Actual Design Meaning
Reverse Voltage (V_R)	100 V - supports high-isolation RF switching in +28 V bias rails without breakdown
Forward Current (I_F)	140 mA - enables robust DC control of RF path insertion loss up to 30 dB attenuation
Diode Capacitance (C_T)	0.25 pF @ 50 V, 1 MHz - ensures minimal signal coupling and phase shift in 800–2600 MHz bands
Zero-Bias Conductance (g_P)	50–100 µS @ 100 MHz - defines on-state RF shunt conductance for precise attenuation slope control
Reverse Recovery Time (τ_rr)	700–1000 ns - determines maximum switching speed in TDD-LTE burst-mode applications
I-Region Width (W_I)	146 µm - directly sets carrier lifetime and linearity performance in high-power RF switches
Thermal Resistance (R_thJS)	≤340 K/W - allows sustained 250 mW dissipation in SOT143 with ≤65°C soldering point temp

Pinout & Package

SOT143 package: 4-pin surface-mount plastic case with exposed thermal pad; pin 1 = anode, pin 2 = cathode, pin 3 = substrate tie (common cathode configuration), pin 4 = unused or isolated.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode	Main RF current entry point; connects to series-switch node or attenuator input leg
Pin 2	Cathode	Common return path for RF and DC bias; tied to ground plane in shunt configuration
Pin 3	Substrate / Cathode Tie	Low-inductance cathode extension for improved high-frequency grounding and thermal conduction
Pin 4	No Connect	Internally isolated; must be left floating or grounded per layout guidelines to avoid parasitic coupling

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAR61H6327XTSA1	SOT143 package, common anode configuration; 0.5 pF C_T @ 50 V (vs. 0.25 pF)	Higher capacitance limits use above 1 GHz; suited for sub-1 GHz ISM band switches	Select when circuit topology requires common-anode layout or lower-cost qualification tier suffices
SMV1232-011LF	SOD-323 package, 0.35 pF C_T, 500 ns τ_rr; no AEC-Q101 qualification	Lacks automotive reliability validation; higher C_T reduces isolation in LTE Band 7	Prefer for cost-sensitive consumer IoT where AEC-Q101 is not mandated

Compared with BAR61H6327XTSA1 and SMV1232-011LF, BAR141E6327HTSA1 delivers superior high-frequency isolation (via 0.25 pF C_T) and automotive-grade reliability - making it optimal for LTE-A carrier aggregation front ends requiring <0.5 dB path loss variation over temperature.

FAQ

What is the maximum RF frequency range supported by BAR141E6327HTSA1?

The BAR141E6327HTSA1 is characterized for operation from 10 MHz up to 2.6 GHz, with verified performance in LTE Bands 1–7 and 40. Its 0.25 pF capacitance at 50 V and 5.5 Ω forward resistance at 100 MHz enable usable insertion loss and isolation through 3 GHz, though datasheet specifications are guaranteed only to 2.6 GHz.

Does BAR141E6327HTSA1 require external DC blocking capacitors in RF paths?

No - the SOT143 package provides inherent DC isolation between RF ports; however, external 1 nF DC blocking capacitors are recommended at input/output nodes in attenuator networks (per Infineon Application Circuit EHM07026) to prevent bias feed-through and maintain impedance stability across 50 Ω systems.

How does BAR141E6327HTSA1's AEC-Q101 qualification impact its use in industrial applications?

AEC-Q101 qualification mandates extended temperature cycling (−55 °C to +125 °C), mechanical shock, and humidity testing - resulting in proven reliability for industrial environments with wide ambient swings and vibration exposure. This translates to >10× longer field life versus non-qualified PIN diodes in motor drive RF feedback loops or outdoor sensor gateways.

Can BAR141E6327HTSA1 be used in parallel configurations for higher power handling?

Parallel use is not recommended due to mismatched I-region widths and thermal gradients causing current hogging. Infineon specifies single-device operation only; for >250 mW average power, system-level derating or discrete heat sinking per device is required - confirmed by thermal simulation data in Application Note Thermal Resistance (2007-04-19).
