Overview

Description

BAT54S-QR is a dual Schottky barrier diode in an SOT-23 package with a common-cathode configuration (two diodes share a cathode).
Key points:
- Applications: fast, low-drop diodes for logic clamping, diode-ORing, level shifting, and small-signal protection in compact circuits.
- Electrical (typical): VR ≈ 30 V; IF(AV) ≈ 200 mA per diode; VF ≈ 0.2–0.5 V at modest forward current; IR is in the microamp range at room temperature (increases with temperature).
- Pinout (SOT-23): Pin 2 = common cathode; Pins 1 and 3 = anodes (A1 and A2).
- Packaging note: The “-QR” suffix usually denotes a specific packaging/leadform option (often tape-and-reel) used for automated assembly; verify exact details from the datasheet/distributor.
In short, BAT54S-QR provides a compact, low‑voltage, fast-switching dual diode solution with a common cathode, suitable for small-signal and protection roles in digital and mixed-signal circuits.

Features

Here are typical features of BAT54S-QR (dual Schottky diodes in one package, QR packaging):
- Dual Schottky barrier diodes in a single SOT-23 package
- Common terminal (BAT54S variant: common cathode)
- Very low forward voltage drop (typ ~0.2–0.3 V at small currents)
- Ultra-fast switching (no reverse recovery)
- Reverse voltage rating: VR ≈ 30 V
- Forward current rating: IF(AV) ≈ 200 mA
- Low leakage current at room temp (increases with temperature)
- Wide operating temperature: −55°C to +150°C
- RoHS compliant, lead-free, halogen-free
- Packaging: Tape-and-reel (QR) for automated assembly
Common uses: clamping, level-shifting, protection, and small-signal switching.

Package

The BAT54S-QR is a dual-series Schottky diode in a 3-pin SOT-23 surface-mount package, typically supplied on tape-and-reel (QR) for automated assembly.

Pinout

Pin count: 3 pins (SOT‑23 package).
Function: The BAT54S-QR is a dual Schottky barrier diode arranged in series (two Schottky diodes with a junction brought out). It provides low forward voltage and fast switching for tasks such as polarity protection, level clamping, steering/OR’ing, and general high-speed rectification in low‑voltage circuits. The three pins are the two end terminals and the center junction between the diodes.

Manufacturer

BAT54S-QR is a BAT54S Schottky diode part marketed by Diodes Incorporated (and the BAT54S family is also made by other semiconductor manufacturers such as Nexperia, Vishay, ON Semiconductor, and ROHM). Diodes Incorporated is a global semiconductor company that designs and supplies discrete components, logic, analog/mixed-signal ICs and power-management devices.

Application

BAT54S-QR is a dual Schottky diode pair (low forward drop, fast switching) in SOT-23. Typical applications:
- Low-current rectification in compact power supplies
- Rail OR-ing and reverse-polarity protection
- Input protection/clamping for microcontrollers and logic
- RF envelope detectors, demodulators, and mixer circuits
- Fast switching/level-shifting in digital/communication circuits
- Peak detectors and clipping/limiting circuits

Equivalent

Equivalent parts (dual Schottky diode pair in
SOT-23, common anode) include:
- On Semiconductor BAT54S-QR
- Nexperia BAT54S
- Vishay BAT54S
These share similar specs (around 30 V, ~0.25–0.5 A) and pinout; “-QR” just denotes tape/reel packaging. Always verify exact pinout and ratings in the datasheet for your BOM.
