概述

Description

BAT54WT1G is a dual Schottky barrier diode in a single small SMD package (BAT54W family). It provides two fast, low-forward-voltage diodes in one device, useful for high-speed rectification, clamping, level-shifting, and input protection in compact boards.
Key points:
- Low forward voltage (typ. 0.25–0.35 V) and very fast switching
- Rated per diode: reverse voltage ~30 V; forward current up to ~200 mA (IF(AV))
- RoHS-compliant, available in a small SMD package (pinout varies with the exact variant)
Note: The two diodes share a common terminal (common anode or common cathode depending on variant). Always consult the manufacturer’s datasheet for the exact pinout, electrical characteristics, and packaging details for BAT54WT1G. If you need, I can pull out the specific pin configuration and a typical application circuit.

Features

Here are concise features of BAT54WT1G:
- Dual Schottky barrier diodes in a single W/SOT-23 package (with a common terminal)
- Reverse voltage: 30 V
- Forward current: 0.2 A (per diode)
- Low forward voltage drop: typically ~0.25 V at 5–10 mA
- Very fast switching and low capacitance
- RoHS compliant (halogen-free)
- Tape/Reel packaging: T1G variant
- Operating temp range: -55°C to +125°C
Ideal for high-speed logic, OR-ing, and clamping in compact SMT designs.

Package

BAT54WT1G comes in a SOT-23 (SC-70 family) 3-pin surface-mount package.

Pinout

Pin count: 3 pins (SOT-23 package).
Function: Dual Schottky barrier diodes in one package with a common terminal (BAT54W variants typically have a common cathode). Used for fast switching, OR-ing, clamping, and reverse-polarity protection.

Manufacturer

- Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.)
- About the company: ROHM is a Japanese multinational semiconductor company that designs and manufactures electronic components, including diodes, transistors, ICs, power devices, and LEDs.

Application

BAT54WT1G is a dual Schottky diode (common-cathode) in one package with low forward voltage and fast switching. Typical applications:
- Reverse/polarity protection for batteries, USB, and power rails
- OR-ing power from multiple sources
- Input clamping and level-shifting for MCUs
- Fast rectification in small DC power supplies and detectors
- RF/telecom envelope detection and transient protection in portable electronics

Equivalent

Equivalent parts for BAT54WT1G (dual Schottky diodes in SOT-23) include:
- BAT54S (dual Schottky, common cathode)
- BAT54C (dual Schottky, common anode)
Both from Nexperia/Vishay and share similar ratings (about 30V, ~200 mA). Ensure you match the diode configuration (anode/cathode) to your schematic.
