BAR 63-05 E6433

RF Diode Overview

The BAR 63-05 E6433 is a silicon PIN diode from Infineon Technologies, designed for high-frequency switching and attenuation applications. It features a low forward voltage drop of 1.2 V at 10 mA and a maximum reverse voltage of 35 V. The device operates with a typical junction capacitance of 0.7 pF at 0 V reverse bias, enabling fast switching speeds suitable for RF circuits. Packaged in the compact SOD-323 surface-mount format, it supports a continuous forward current of 200 mA and dissipates up to 330 mW of power. The component functions reliably across an extended temperature range from -65 °C to +150 °C.

RF Diode Feature Summary

• Low junction capacitance for minimal signal loss in RF paths
• High thermal stability with elevated maximum junction temperature rating
• Compact SOD-323 package for space-constrained PCB layouts

RF Diode Applications

• RF switch circuits requiring low insertion loss
• Variable attenuators in communication systems
• Antenna switching modules

RF Diode Procurement Notes

Verify the specific suffix E6433 against official Infineon documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through the manufacturer's latest declaration. Check for end-of-life notices or alternative recommendations directly from Infineon sales channels before finalizing procurement plans.

RF Diode Selection Notes

Select this component when low parasitic capacitance is critical for maintaining signal integrity at radio frequencies. Ensure the operating environment stays within the specified -65 °C to +150 °C range. Verify that the required forward current does not exceed 200 mA continuously to prevent thermal overload in the SOD-323 package.

RF Diode Part Context

This part belongs to Infineon's BAR series of silicon PIN diodes, which are engineered for RF and microwave applications. The BAR 63-05 variant specifically targets high-speed switching needs where low charge storage and fast recovery times are essential. It complements other components in RF front-end designs by providing precise control over signal paths.

RF Diode Replacement Considerations

Consult Infineon's official cross-reference tools for verified substitutes. Generic PIN diodes may lack the specific capacitance and speed characteristics required for this application.
