Schottky pair for RF detection and mixing
The Infineon BAT1704E6327HTSA1 is a series-connected Schottky diode pair in a SOT-23-3 package, designed for low-level RF detection, mixing, and sampling circuits where fast switching and low junction capacitance matter. The 0.75 pF capacitance at zero bias keeps signal loading minimal up into the gigahertz range, while the 15 Ohm series resistance at 5 mA defines the insertion loss floor for detector sensitivity. Peak reverse voltage is 4 V, so this part stays in low-voltage front-end roles — think RF power monitoring, envelope detection, or high-speed switching up to 130 mA.
Capacitance is 0.75 pF at 0 V, 1 MHz. Series resistance is 15 Ohm at 5 mA, 10 kHz.
