BAT85 small-signal Schottky diode for low-forward-voltage switching and signal protection. This is a through-hole DO-35 axial diode rated for 30V reverse voltage and 200mA forward current. Why use this instead of a generic signal diode? Lower forward voltage than a standard silicon switching diode, useful where you need a clamp or signal path to conduct earlier. Fast small-signal behavior for probe, endstop, detection, and low-current electronics circuits. Axial DO-35 glass package is easy to solder inline or into through-hole boards. Specifications Part family: BAT85 Schottky barrier diode Package: DO-35 / DO-204AH axial glass Reverse voltage: 30V Forward continuous current: 200mA Typical forward voltage: 0.24V at 0.1mA, 0.32V at 1mA, 0.40V at 10mA Quantity: single diode Intended use Use it for low-current electronics work, probe/endstop signal protection, or repairs where a BAT85-family Schottky diode is specified. In Voron-style printer builds, it is commonly paired with inductive probe wiring such as the Omron TL-Q5MC2-Z NPN NC probe; always follow your controller board wiring documentation. What it is not Not a high-current rectifier or heater-bed power diode. Not a Zener diode, TVS diode, or general replacement for every protection circuit. Not required on every CAN toolhead or controller board; check the board's probe input design first.
