What the 0.23 pF capacitance buys the RF front-end
The BAT2402LSE6327XTSA1 is a single Schottky diode from Infineon, specified for a peak reverse voltage of 4V and a maximum forward current of 110 mA. Its junction capacitance is 0.23 pF at 0V bias and 1 MHz.
The 4V peak reverse rating is the hard ceiling: this diode is designed for sub-3.3V rails, not for 5V or 12V power buses. Use it for low-voltage signal conditioning, RF envelope detection, or protection on 1.8V and 2.5V I/O lines. The 100 mW power dissipation limit reinforces that this is a signal-level device, not a rectifier for any appreciable load.
150°C junction temperature — thermal headroom for tight enclosures
Rated for a maximum junction temperature of 150°C, the BAT2402LSE6327XTSA1 can sit on a board near a hot processor or power inductor without derating. The 0201 package has minimal thermal mass, so the 150°C rating is the silicon limit, not the package limit — the board copper area and ambient airflow will set the real thermal budget.
Infineon lists the BAT2402LSE6327XTSA1 as Active. The part is ROHS3 compliant.
