概述

Description

BAV99-QR is a dual high‑speed silicon switching diode in a single SMD package (commonly SOT‑23) used for fast signal switching, clipping, demodulation, and protection in small‑signal circuits. The “-QR” suffix denotes a specific packaging/reel variant from manufacturers (e.g., tape‑and‑reel). Always refer to the datasheet for exact package details, pinout, and voltage/current ratings. Key traits are fast switching speed, low leakage, and low capacitance, making it suitable for high‑speed logic and signal paths. Electrical ratings (reverse voltage and forward current) vary by vendor, so verify the exact numbers for your supplier. If you need a different package or reel option, alternatives in the BAV99 family (e.g., BAV99W) may be available. In short: a compact dual fast diode network for small‑signal switching and protection, with QR indicating a specific packaging version.

Features

BAV99-QR features (concise):
- Dual fast switching diodes in a single SOT‑23 package (two diodes in series with a center tap).
- Three-terminal device suitable for high-speed switching, clipping, level shifting, and small-signal circuits.
- RoHS compliant with QR (Tape & Reel) packaging for automated assembly.
- Low parasitic capacitance and fast recovery for quick signal transitions.
- Typical electricals (per package): VRRM around 75 V; IF(AV) about 150 mA (through the series path); low leakage.
- Compact, inexpensive, mass-manufacturable for surface-mount designs.

Package

The BAV99-QR is the dual-series switching diode in a SOT-23 (TO-236) surface-mount package. The “-QR” suffix typically denotes tape-and-reel packaging for automated assembly.

Pinout

Pin count: 3 pins (SMD package, e.g., SOT-23/SOD523).
Function: BAV99-QR is a dual small‑signal switching diode pair wired in series. Typical pinout (top view):
- Pin 1 = Anode of D1
- Pin 2 = Common junction (cathode of D1 / anode of D2)
- Pin 3 = Cathode of D2
Used for high‑speed switching, signal clipping, level shifting and protection in RF/logic/signal paths.

Manufacturer

Multiple semiconductor companies manufacture the BAV99-QR (for example Diodes Incorporated and Vishay). These makers are semiconductor manufacturers that design and produce discrete semiconductor components (switching diodes, transistors, rectifiers and related analog/power devices).

Application

BAV99-QR is a dual high-speed switching diode in a compact SMD package. Applications include:
- Fast signal switching and level shifting
- Demodulation, envelope detection, and peak rectification (RF/IF, audio)
- Clipping/limiting and waveform shaping
- Input protection and clamping for logic/ICs and op-amps
- Diode-OR/AND logic and small-signal detectors
Note: suitable for general-purpose small-signal applications requiring fast response.

Equivalent

Equivalent/compatible parts for a BAV99-QR dual series switching diode include MMBAV99 (SMD version), BAW99, 1SS355 and generic BAV99 devices from major vendors (Diodes Inc., ON Semiconductor, Nexperia). Any dual-series switching diode in SOT‑23 with similar ratings (VRRM ≈70 V, IF/IR and Vf specs matching) is typically interchangeable—check datasheets for exact parametric matches.
