BAT54H

BAT54H is a dual Schottky diode device in a SOT-23 package, part of the BAT54 family. It contains two Schottky diodes with a common node, enabling compact, fast, low-drop rectification and clamping for small-signal and protection tasks. Common uses include input protection, level shifting, diode-OR, and low-voltage switching where a fast response and low forward voltage are important.
Key points:
- Very low forward voltage (roughly 0.2–0.4 V at modest current) and fast switching (no recovery time).
- Reverse voltage typically in the 20–30 V range; forward current capability depends on the exact variant.
- Three-lead SOT-23 package; the two diodes share a common terminal (anode or cathode depending on variant).
Note: The H suffix identifies a specific BAT54H variant; check the exact datasheet for the precise pinout and electrical ratings for your design.

Equivalents are other vendors’ dual Schottky diodes in SOT-23 with the same pinout and ratings as BAT54H. To give precise cross-references, please confirm the package (SOT‑23/SC‑70), the exact configuration (common cathode vs common anode), and the voltage/current specs you need.

BAT54H is a dual Schottky diode in SOT-23 with a common cathode configuration. Key features:
- Dual Schottky diodes, common cathode, three-pin SOT-23 package
- Reverse voltage VRRM: 30 V; forward current IF(AV) ~200 mA per diode
- Very low forward voltage drop (typ ~0.25 V at modest current; rises slightly with higher current)
- Fast switching with negligible reverse recovery
- Low leakage current (reverse) and suitable for high-speed/low-power apps
- Wide operating temperature range (typically -55°C to +125°C)
- Applications: OR-ing, clamping/protection, level shifting, and other high-speed, low-voltage tasks
Note: exact numbers can vary by manufacturer; check the specific datasheet for your part variant.
