Small-signal Schottky for RF detector and mixer work
The Infineon BAT17E6327HTSA1 is a single Schottky diode in a SOT-23-3 package, rated for a maximum forward current of 130 mA and a peak reverse voltage of 4 V. Its key distinguishing features are the low junction capacitance of 0.75 pF at 0 V and a series resistance of 15 Ohm at 5 mA, which together make it suited for RF detector, mixer, and clamping applications where signal integrity at high frequencies matters. The 150°C junction temperature rating gives thermal headroom in compact or warm enclosures.
The 130 mA rating is the absolute maximum. Signal-level currents are typically well below 10 mA.
Package and rework — SOT-23 is a bench-friendly footprint
The SOT-23-3 (PG-SOT23) package has three pins and low thermal mass. It lifts clean with hot air without damaging the board.
