概述

Description

BAT54C-QR is a dual Schottky barrier diode in one SOT-23 package with a common cathode. The “-QR” suffix typically indicates tape-and-reel packaging for automated assembly.
Key points
- Configuration: two diodes share a common cathode (anodes at pins 1 and 3; pin 2 is the common cathode).
- Performance: very low forward voltage drop (Schottky), fast switching, suitable for high-speed and low-voltage circuits.
- Ratings (per diode, typical): reverse voltage ~30 V; forward current around 200 mA; low reverse leakage.
- Applications: OR-ing or combining signals, input protection, level shifting, clamping, fast switching circuits.
- Packaging: surface-mount, SOT-23; -QR indicates reel packaging.
Notes
- Check the exact datasheet for precise Vf, Ir, and current limits for your lot and temperature range.
- Common alternatives in the BAT54 family differ in anode/cathode arrangement (A, C, S variants).

Features

Here are concise features of BAT54C-QR:
- Dual Schottky barrier diodes in one package with common cathode (BAT54C) configuration.
- Package: SOT-23-3 with QR indicating Tape & Reel packaging.
- Voltage/current ratings: VRRM ~30 V; IF(AV) ~200 mA per diode.
- Very low forward voltage drop (typ. ~0.25–0.35 V at tens of mA), enabling high efficiency.
- Fast switching with negligible reverse recovery (Schottky type).
- Low reverse leakage current (a few microamps at room temp; increases with temp).
- Low junction capacitance for high-speed applications.
- Temperature range typically -55°C to +125°C; RoHS compliant, lead-free.
- Applications: OR-ing, protection, level shifting, high-speed switching.
Note: exact numbers (e.g., VF, IR, Cj) are in the datasheet; use those for precise design.

Package

The BAT54C-QR is a dual Schottky diode in a 3‑pin SOT‑23 (TO‑236AB) surface‑mount package.

Pinout

3 pins. It is a dual Schottky diode array with a common anode (BAT54C family) in a SOT-23/QR package.

Manufacturer

Manufacturer: Diodes Incorporated.
What kind of company: Diodes Incorporated is a global semiconductor manufacturer that designs and supplies discrete, logic and analog semiconductor components (including diodes, transistors, rectifiers and power-management ICs). It is a publicly traded company headquartered in Plano, Texas (NASDAQ: DIOD).

Application

BAT54C-QR is a dual common-cathode Schottky diode in SOT-23 (Tape & Reel). Low forward voltage and fast switching suit:
- Power-rail and logic OR-ing with reverse-current protection
- Input/output protection and diode-OR level shifting for MCUs and digital ICs
- High-speed switching/rectification in digital, RF, and EMI-sensitive circuits
- General low-voltage clamping and protection in portable devices
(Uses: two sources feeding one load, signal conditioning, protection in low-voltage logic.)

Equivalent

BAT54C-QR is a dual Schottky diode pair in SOT-23 with a common cathode (≈30 V, 0.2 A). Equivalents: BAS54C (common-cathode dual Schottky, SOT-23) and other vendors’ BAT54C-compatible parts. Any dual Schottky in SOT-23 with common cathode and similar ratings can substitute; verify forward drop and leakage.
