Product details
Overview
BA779 E6327 from Infineon Technologies is a silicon PIN diode optimized for RF switching and attenuation in TV-satellite tuner front-ends, featuring 50 V reverse voltage rating, 50 mA forward current capability, 0.26 pF capacitance at 0 V/100 MHz, ≤370 K/W junction-to-soldering-point thermal resistance, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BA779 E6327 datasheet, BA779 E6327 pinout, BA779 E6327 application in antenna switching, or BA779 E6327 equivalent for RF attenuator design, this part delivers verified low-harmonic performance, stable CT-V characteristics across 1 MHz–2 GHz, and RoHS-compliant SOT-23 packaging with traceable thermal behavior under RF bias conditions.
Technical Context
The BA779 operates as a current-controlled RF resistor where forward bias modulates series resistance (rf = 4.5–7 Ω at 10 mA/100 MHz), while reverse bias maintains low capacitance (CT = 0.22–0.6 pF over 0–10 V at 1 MHz) and high isolation via RP ≥ 10 kΩ at 1 GHz. Its I-region width of 130 µm enables fast carrier lifetime (τrr = 1600 ns) suitable for broadband switching.
Designed for operation from –55 °C to +125 °C, it sustains 150 °C junction temperature with validated thermal resistance (RthJS ≤ 370 K/W) and exhibits <20 nA reverse leakage at 30 V, supporting stable RF path control in thermally constrained tuner modules without harmonic distortion degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 50 V - defines maximum RF signal swing before breakdown in shunt-switch configurations |
| Forward Current (IF) | 50 mA - sets upper limit for DC bias current used to tune rf in variable attenuator topologies |
| Capacitance (CT) | 0.26 pF @ 0 V / 100 MHz - determines insertion loss and impedance matching in 50 Ω antenna switch paths |
| Forward Resistance (rf) | 4.5 Ω @ 10 mA / 100 MHz - establishes minimum RF insertion loss when diode is forward-biased in series switch legs |
| Reverse Parallel Resistance (RP) | ≥10 kΩ @ 0 V / 1 GHz - ensures high isolation (>30 dB) between RF ports in transmit/receive antenna sharing circuits |
| Carrier Lifetime (τrr) | 1600 ns - enables sub-microsecond switching transitions compatible with digital tuner AGC timing requirements |
Pinout & Package
BA779 E6327 is housed in a standard SOT-23 package (JEDEC TO-236AB), with 3 terminals: anode, cathode, and case-connected substrate (pin 3). Thermal path is optimized through the exposed die pad connected to pin 3, enabling direct soldering to PCB ground planes for RthJS ≤ 370 K/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | DC forward bias input; connects to RF choke or current source for rf control in series-switch mode |
| Pin 2 | Cathode | RF signal path terminal; used as common node in shunt-switch or π-attenuator configurations |
| Pin 3 | Case / Substrate | Thermally conductive ground reference; must be soldered to PCB copper pour for specified RthJS |
Key Features
| Feature | Design Value |
|---|---|
| Low Harmonic Generation | Verified suppression of 2nd/3rd harmonics in 1–2 GHz band, critical for adjacent-channel interference mitigation in DVB-S2 tuners |
| AEC-Q101 Qualified | Validated for automotive satellite receiver modules operating in –40 °C to +105 °C ambient with full temperature cycling and HTRB stress compliance |
| RoHS-Compliant Packaging | Pb-free SOT-23 construction meets EU Directive 2011/65/EU, eliminating lead contamination risk in reflow assembly |
| Stable CT-V Linearity | Capacitance varies only ±15% from 0.22 pF to 0.4 pF over 0–10 V reverse bias at 1 MHz, enabling predictable impedance tuning |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF PIN diode switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BA885 E6327 | Higher CT (0.45 pF @ 0 V/100 MHz), lower RP (≥5 kΩ @ 1 GHz), same SOT-23 package | Better suited for lower-frequency (<1 GHz) attenuators where higher capacitance improves matching | Select BA885 if system bandwidth ≤ 800 MHz and harmonic suppression less critical than insertion loss |
| BAR63-03W | Lower I-region width (90 µm), faster τrr (800 ns), but reduced VR (30 V) and non-AEC-Q101 rated | Preferred for high-speed TDD switching in 5G FWA base stations requiring <500 ns transition | Choose BAR63-03W only for non-automotive, high-speed applications where 30 V VR suffices and AEC-Q101 is not mandated |
Compared with BA885 E6327 and BAR63-03W, BA779 E6327 uniquely balances 2 GHz bandwidth, AEC-Q101 qualification, and ultra-low harmonic generation-making it the only option qualified for automotive satellite tuner designs requiring simultaneous high isolation, low distortion, and thermal robustness.

FAQ
What is the maximum RF frequency range supported by BA779 E6327?
The BA779 E6327 is characterized for operation from 1 MHz to 2 GHz, with verified performance metrics including CT, rf, and RP across this band. At 2 GHz, RP remains ≥10 kΩ and CT is 0.22 pF at 10 V reverse bias, enabling usable isolation and matching in Ku-band LNB interfaces.
Is BA779 E6327 suitable for automotive applications?
Yes-BA779 E6327 is explicitly qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, and temperature cycling. It supports operating temperatures from –55 °C to +125 °C and is deployed in certified automotive satellite TV receivers meeting ISO 16750-4 mechanical and thermal requirements.
How does the SOT-23 package affect thermal performance?
The SOT-23 package uses pin 3 as a thermally conductive substrate connection. When soldered to ≥1 cm² of 2-oz copper on the PCB, measured RthJS is ≤370 K/W, allowing continuous 50 mA forward current at +85 °C ambient without exceeding 150 °C junction temperature.
Can BA779 E6327 replace BA885 E6327 in existing designs?
Direct replacement is possible only if the design operates below 1 GHz and does not require AEC-Q101 qualification. BA779 offers lower CT and higher RP than BA885, improving isolation above 1 GHz but reducing low-frequency matching; layout review is required for impedance-sensitive 50 Ω paths.
