BAR63

RF Diode Overview

The Infineon BAR63 is a PIN diode configured as a common anode pair, designed for RF switching applications. It operates within a voltage range of up to 50V reverse and supports a maximum forward current of 100mA. Key electrical parameters include a typical carrier lifetime of 75ns, a maximum forward voltage of 1.2V, and a low capacitance of 0.3pF at zero bias. The device is housed in a compact SOD-323 (PG-SOT323) surface-mount package with dimensions of 1.7 x 1.25 x 0.9mm. It functions reliably across a temperature range of -55°C to +125°C.

RF Diode Feature Summary

• Common anode pair topology suitable for balanced RF circuits

RF Diode Procurement Notes

Verify the specific ordering suffix (e.g., H6327XTSA1) against the manufacturer's current datasheet to confirm availability and packaging details. Note that certain variants within the BAR63 family may be discontinued; always cross-reference the full part number with official Infineon resources to ensure compliance with current production status and RoHS directives before procurement.

RF Diode Selection Notes

Select the BAR63 when a dual-diode configuration with a shared anode is required for RF isolation or switching. Ensure the application voltage does not exceed the 50V reverse limit and that the forward current remains within the 100mA specification. Verify that the SOD-323 footprint matches the board design constraints and that the thermal operating range covers the intended environment.

RF Diode Part Context

The BAR63 series belongs to Infineon's portfolio of PIN diodes optimized for radio frequency applications. These components utilize specialized semiconductor processes to achieve fast switching speeds and low insertion loss. The common anode configuration allows for efficient control of multiple RF lines using a single bias point, simplifying circuit design in communication equipment.

RF Diode Replacement Considerations

Check for updated versions such as BAR63-06W or BAR63-03W. Confirm pinout compatibility and electrical parameter equivalence before substitution.
