PIN diode pair for RF switching and attenuation
The Infineon BAT1804E6327HTSA1 is a PIN diode array with two diodes in a series pair configuration, housed in a PG-SOT23 package. It handles a peak reverse voltage of 35V and a maximum forward current of 100 mA. The key characteristic for RF designers is the low capacitance: 1pF at 20V reverse bias and 1 MHz, which keeps insertion loss low in switch and attenuator circuits up through UHF bands.
ROHS3 compliance is confirmed, which simplifies EU and global regulatory acceptance.
For dual-source planning, Infineon's BAT18 series includes other PIN diode configurations, but no direct pin-compatible second source from another manufacturer is listed in the record.
