BAT54WT1G

BAT54WT1G is a dual Schottky barrier diode in a compact SOT-23W package. It contains two fast, low forward‑voltage diodes with a common terminal, suitable for low‑voltage OR‑ing, level shifting, input protection, and high‑speed switching in small circuits. Key specs (typical): reverse voltage about 30 V; forward current about 0.2 A per diode; forward voltage around 0.2–0.3 V at modest current; very fast switching. Operating range roughly −55 to +125 °C. The 1G suffix denotes a RoHS‑compliant package/reel variant and date code per the manufacturer. Pinout is three terminals with a shared node; whether the shared node is a common anode or common cathode depends on the exact variant, so check the datasheet for your specific part marking. In short, BAT54WT1G offers a small, efficient dual Schottky option for low‑voltage, high‑speed diode needs.

Equivalent products: other BAT54‑family Schottky diodes with the same package and ratings — e.g. BAT54W, BAT54S, BAT54C or generic BAT54 parts from Nexperia, Diodes Inc., ON Semiconductor, Vishay. Similar-function substitutes (different packages) include BAS40 or SS14. Always confirm package/pinout, VR, IF and Vf in the datasheets before substituting.

BAT54WT1G features (concise):
- Dual Schottky barrier diodes in one SMD package (BAT54W), common cathode configuration.
- Very low forward voltage drop (≈0.2–0.3 V at low currents) for efficient signaling/OR-ing.
- Fast switching; negligible reverse recovery.
- Reverse voltage rating: typically 30 V.
- Forward current rating: about 200 mA per diode (0.4 A total if both conduct).
- Low leakage at room temp; increases with temperature.
- Wide operating temp range: roughly -55°C to +125°C.
- RoHS-compatible, Pb-free package (surface-mount).
- Applications: level shifting, protection, input gating, OR-ing, clamping.

- Pin count: 3 pins (SOT-23 package).
- Function: dual Schottky barrier diodes (two Schottky diodes in one package) for low forward-voltage, fast switching and low-leakage applications — commonly used for level shifting, clamp/peak detection, polarity protection and general high-speed switching.

BAT54WT1G is a common dual Schottky diode part number produced by multiple semiconductor manufacturers (examples include Diodes Incorporated, Vishay, Nexperia and ON Semiconductor). Each of those manufacturers is a semiconductor company that designs and produces discrete components (diodes, transistors), analog and logic ICs, and power-management devices for the electronics industry.

BAT54WT1G is a dual Schottky diode with very low forward voltage and fast switching. Common application areas:
- Input protection and clamping for microcontrollers/IC interfaces
- Diode-ORing and power-path switching for multiple supplies
- Low- to moderate-current rectification in DC–DC converters and charge pumps
- Level shifting and protection in 3.3V/5V logic systems
- Reverse-polarity protection for battery-powered devices
- Fast switching/edge-detection in signaling and RF front-end circuits

The BAT54WT1G is supplied in a 3-pin SOT-23 (surface-mount) package.
