概述

Description

SBAT54CWT1G is a dual Schottky barrier rectifier in a SOT-23 package. The “C” indicates a common-cathode configuration (two diodes share a cathode). Key specs (typical): VRRM about 30 V per diode, IF(AV) ≈ 200 mA, low forward voltage drop (VF ~0.25–0.40 V at 0.1–0.2 A), and fast switching. The “WT1G” suffix denotes the package/traceability code (RoHS-compliant, lead-free SOT-23). Applications include low-loss rectification, polarity protection, and input/output OR-ing in small power supplies and logic circuits.

Features

Here are concise features for SBAT54CWT1G:
- Dual Schottky barrier diodes (BAT54C), common-cathode configuration
- VRRM: 30 V
- IF(AV): 200 mA per diode
- Very low forward voltage drop (typical around 0.2–0.3 V at low currents; low VF supports efficiency)
- Fast switching with no minority-carrier storage
- Low reverse leakage for Schottky diodes (suitable for low‑power apps)
- Small SOT-23 package (3 leads)
- RoHS compliant, Pb-free (green)
- Temperature range: typically -55°C to +125°C
- Applications: polarity protection, diode-ORing, level shifting, clamping, high-speed rectification
Note: for exact VF and IR specs at specific currents/temperatures, refer to the datasheet.

Package

SOT-23 package (3-pin, SC-70 family), dual Schottky with common cathode.

Pinout

- Pin count: 3 pins (SOT-23 package)
- Function: Dual Schottky barrier diode with a common cathode (two diodes share the cathode). Pin 1 and Pin 3 are the anodes of D1 and D2, respectively; Pin 2 is the common cathode. Used for low-forward-voltage, fast-switching diode applications (OR-ing, level shifting, protection).

Manufacturer

Manufacturer: Vishay Intertechnology (Vishay).
What kind of company: A global manufacturer of electronic components and semiconductors, including diodes, transistors, resistors, capacitors, and related passive components.

Application
