Product details
Overview
BAR6302LE6433XT 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 BAR6302LE6433XT datasheet, BAR6302LE6433XT pinout, BAR6302LE6433XT application, or BAR6302LE6433XT equivalent, key selection criteria include RF isolation above 12.3 dB at 1.8 GHz, reverse voltage rating of 50 V, low-charge-carrier lifetime (75 ns), and SOD323 package compatibility with high-frequency PCB layout constraints.
Technical Context
This PIN diode operates as a voltage-controlled RF switch in series topology, leveraging its low I-region width (4.5 µm) and fast carrier lifetime (75 ns) to enable sub-nanosecond switching transitions. Its RF performance is defined by low CT (≤0.3 pF) and high RP (≥500 kΩ at 100 MHz), supporting broadband operation up to 3 GHz.
The device uses a single-diode configuration in SOD323 package with anode and cathode terminals only - no integrated bias network or matching elements. Thermal resistance (RthJS ≤ 380 K/W) and 250 mW total power dissipation are specified for continuous DC operation at TA = 25°C.

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 |
|---|---|---|---|
| SKY13370-374LF | Higher capacitance (0.35 pF), lower Rf (0.8 Ω), integrated matching network | Designed for 50 Ω matched front-end use; requires no external DC blocking | Prefer when board space is constrained and matching components must be minimized |
| MA4P7472F-1072T | Lower max IF (50 mA), higher CT (0.4 pF), TO-236AB package | Optimized for test equipment; larger footprint and higher thermal resistance (RthJS = 450 K/W) | Prefer for lab-grade RF switches where solderability and probe access matter more than size |
Compared with SKY13370-374LF and MA4P7472F-1072T, BAR6302LE6433XT offers the lowest capacitance and best isolation-to-loss ratio in SOD323, making it optimal for miniaturized, high-frequency mobile RF front ends where layout parasitics dominate performance.

FAQ
What is the maximum RF frequency supported by BAR6302LE6433XT?
The device is characterized for operation up to 3 GHz, with verified performance metrics including 12.3 dB isolation at 1.8 GHz and 10 dB isolation at 2.45 GHz. Measured insertion loss remains below 0.15 dB through 1.8 GHz, and S-parameter data confirms usable response beyond 2.5 GHz in 50 Ω systems with proper layout.
Can BAR6302LE6433XT be used in series-shunt switching configurations?
No - BAR6302LE6433XT is a single-diode device in SOD323 package with only anode and cathode terminals. It supports series-switch topology only. Shunt or series-shunt configurations require dual-diode packages like BAR63-04W or external discrete placement of second diode with appropriate DC blocking.
What is the recommended DC bias current for optimal RF performance?
For minimal insertion loss and stable resistance, use 5–10 mA forward current. At 5 mA, forward resistance is 1.2 Ω and insertion loss is 0.11 dB at 1.8 GHz; at 10 mA, resistance drops to 1.0 Ω but thermal rise increases. Do not exceed 100 mA DC or 250 mW total dissipation to avoid junction overheating.
Is BAR6302LE6433XT suitable for automotive applications?
No - this variant (BAR63-02L) is explicitly noted as "not qualified according AEC Q101" in the official datasheet. While it shares construction with AEC-Q101-qualified variants like BAR63-02V, BAR6302LE6433XT lacks the required stress testing, lot traceability, and failure analysis documentation for automotive use.
