Product details
Overview
BAR6302LE6327XTMA1 from Infineon Technologies is a silicon PIN diode optimized for high-speed RF signal switching in series configuration, featuring 0.21 pF capacitance at 5 V/1 MHz, 1.2 Ω forward resistance at 5 mA/100 MHz, and insertion loss of 0.11 dB at 1.8 GHz - deployed in cellular front-end modules and antenna tuning circuits.
For engineers reviewing the BAR6302LE6327XTMA1 datasheet, BAR6302LE6327XTMA1 pinout, BAR6302LE6327XTMA1 application, or BAR6302LE6327XTMA1 equivalent, key selection criteria include low-capacitance switching performance up to 3 GHz, thermal resistance ≤125 K/W, AEC-Q101 qualification status, and SOD-323 package compatibility with high-density RF layouts.
Technical Context
This PIN diode operates as a voltage-controlled RF switch in series topology, leveraging its intrinsic I-region width (4.5 µm) to balance charge carrier lifetime (75 ns) and high-frequency isolation. Its low CT and high RP enable broadband operation from 100 MHz to 2.45 GHz with minimal signal distortion.
The device uses a single-diode, leadless SOD-323 package with anode-cathode polarity defined for unidirectional DC bias control. It requires external bias networks to maintain reverse-biased isolation or forward-biased conduction states during RF signal path selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (CT) | 0.21 pF @ VR = 5 V, f = 1 MHz - enables >17 dB isolation at 0.9 GHz in 50 Ω systems |
| Forward Resistance (rf) | 1.2 Ω @ IF = 5 mA, f = 100 MHz - ensures <0.11 dB insertion loss at 1.8 GHz |
| Reverse Voltage (VR) | 50 V - supports bias headroom for LTE/5G envelope tracking applications |
| Forward Voltage (VF) | 0.95 V typ. @ IF = 100 mA - minimizes power dissipation in continuous-conduction mode |
| Junction Temp (Tj) | 150 °C - allows operation in automotive under-hood RF modules without derating |
| Thermal Resistance (RthJS) | ≤125 K/W - sustains 100 mA DC current with TS ≤ 118 °C in SOD-323 layout |
| Isolation (ISO) | 17.9 dB @ f = 0.9 GHz, VR = 0 V - meets GSM band rejection requirements |
Pinout & Package
BAR6302LE6327XTMA1 is housed in a RoHS-compliant SOD-323 plastic package (2-pin, single diode, leadless), with cathode marked by a white band on the case body.

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 |
|---|---|---|---|
| SMV1232-079LF | 0.25 pF CT, 1.5 Ω rf, SOT-23 package, no AEC-Q101 qualification | Higher insertion loss (0.14 dB @ 1.8 GHz); suited for consumer-grade Wi-Fi, not automotive | Select when cost-sensitive non-automotive designs prioritize footprint over thermal robustness |
| BAP64-03W | 0.23 pF CT, 1.1 Ω rf, SOD-323 package, AEC-Q101 qualified, 500 mW Ptot | Higher power handling but larger series inductance (1.8 nH vs. 0.4 nH) limits >2 GHz use | Prefer for 900 MHz–1.5 GHz automotive telematics where higher surge tolerance is required |
Compared with SMV1232-079LF and BAP64-03W, BAR6302LE6327XTMA1 delivers the lowest combined insertion loss and thermal resistance in SOD-323 for 1.8–2.45 GHz 5G FR1 front-end switching, while maintaining AEC-Q101 compliance without sacrificing RF linearity.

FAQ
What is the maximum RF frequency supported by BAR6302LE6327XTMA1?
The device is characterized for operation up to 3 GHz, with verified isolation and insertion loss data at 0.9 GHz, 1.8 GHz, and 2.45 GHz. At 2.45 GHz, isolation remains ≥10 dB and insertion loss ≤0.15 dB under specified bias conditions, confirming full usability in Wi-Fi 6E and Bluetooth LE applications.
Is BAR6302LE6327XTMA1 AEC-Q101 qualified?
No - BAR6302LE6327XTMA1 corresponds to the BAR63-02L variant, which is explicitly noted in the datasheet as "not qualified according AEC Q101". For AEC-Q101-compliant alternatives in the same family, consider BAR63-02V or BAR63-02W (SOD-323, single diode, qualified).
How does the SOD-323 package affect RF performance?
The SOD-323's short leadframe and compact 1.7 × 1.25 mm footprint minimize parasitic inductance (LS = 0.4 nH), preserving high-frequency response. Its thermal resistance of ≤125 K/W enables reliable 100 mA DC operation without heatsinking, critical for densely packed RF modules.
Can BAR6302LE6327XTMA1 be used in shunt configuration?
No - the BAR63-02L variant is specified only for series configuration per datasheet Figure 1 and isolation/insertion loss test conditions. Shunt use would violate its rated reverse voltage margin and degrade isolation due to package parasitics not characterized in that topology.
