概述

Description

BAV199-QR is a fast, small-signal switching diode in an SMD package. It’s designed for high-speed switching, demodulation, clipping, and signal routing in compact circuits, offering low junction capacitance and fast recovery to preserve waveform integrity in RF and digital applications. The “-QR” suffix typically denotes a specific packaging/line option (often tape-and-reel) from the manufacturer, not a different device type.
Key point: exact electrical specs (reverse voltage, forward current, switching time, capacitance) vary by vendor and variant. Always consult the latest datasheet for BAV199-QR from your supplier to confirm ratings and limits before design or parts purchasing. In short: a fast, general-purpose diode for high-speed signal applications, with packaging variants such as QR for automated assembly.

Features

BAV199-QR features (highlights):
- Fast-switching, small-signal diode for high-speed/ RF applications
- Glass-passivated junction for reliability and stability
- High reverse-voltage capability (VRRM ≈ up to 200 V)
- Forward current in the few-hundred mA range
- Very fast reverse-recovery time (ns range)
- Low reverse leakage and low forward drop
- Surface-mount package in QR (tape-and-reel) format for automated assembly
Note: For exact electrical ratings (VRRM, IF(AV), max leakage, etc.), please refer to the official datasheet.

Package

The BAV199-QR is in a surface-mount SOD-123 (small-outline) diode package.

Pinout

Pin count: 2 pins.
Function: Fast-switching diode (small-signal, high-speed diode).

Manufacturer

- Manufacturer: Vishay Intertechnology, Inc. (Vishay)
- What kind of company: A global, publicly traded semiconductor company that designs, manufactures, and markets discrete semiconductors (e.g., diodes), resistors, capacitors, and other electronic components.

Application

BAV199-QR is a fast-switching diode. Typical applications: high-speed signal routing and switching in RF/telecom and digital circuits; peak- and envelope-detection in demodulators; high-frequency rectifiers; clipping/limiting and waveform shaping; input protection and transient suppression on ICs.

Equivalent

BAV199-QR is a dual high‑speed switching diode. Common equivalents (dual fast diodes in similar SMD packages) include:
- BAV199 (other vendors)
- BAV99
- MMBD4148 / MMBD4148A
- MMB4148
- 1N4148W (SMD version; use two in fuse/dual config as needed)
Note: check reverse voltage (VR) and forward current (IF) and ensure same pinout/package.
