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.
130 mA and 4 V — what they mean for the BOM
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.
Lifecycle and sourcing
The BAT17E6327HTSA1 is listed as Active and ROHS3 compliant. No end-of-life notification has been issued.
