Bat85 Diode
Couldn't load pickup availability
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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
