The Infineon BAR6305WH6327XTSA1 is a silicon PIN diode configured as a 1 pair common cathode in a PG-SOT23 package. It handles a peak reverse voltage of 50 V and a maximum continuous current of 100 mA, with a power dissipation limit of 250 mW. The common-cathode layout pairs two diodes in a single SOT-23-3 footprint, saving board space in RF switch, attenuator, and limiter circuits where the cathodes share a common bias or RF return. This part is rated for a junction temperature up to 150 °C, which covers the thermal environment of compact RF front-end modules and base-station transceiver boards.
Series resistance and capacitance — what they mean for RF performance
Series resistance is 1 ohm at 10 mA and 100 MHz. Off-state capacitance is 0.3 pF at 5 V and 1 MHz.
