概述

Description

BAV199Q-7-F is a dual high-speed switching diode in a small SMD package. It contains two fast diodes in one package, commonly used for fast signal routing, clipping, level shifting, or demodulation in compact circuits.
Notes:
- The Q-7-F suffix indicates a specific manufacturer/package revision; it is typically RoHS/lead‑free.
- Exact pinout (which pin is common anode vs. common cathode) and electrical limits vary by supplier and variant, so always consult the specific datasheet for your lot.
- Typical parameters to verify: reverse voltage (VR), forward current (IF), switching times (tf/tr), and junction capacitance (Cj).
Common applications:
- High‑speed logic interfaces and fast signal processing
- Clip/clipper and rectifier functions
- Demodulation and RF front‑end tasks in tight PCB layouts
In short: it’s a compact dual fast-switching diode; confirm the exact variant from your supplier for pinout and electrical specs before design use.

Features

BAV199Q-7-F is a fast, general‑purpose small-signal diode in an automotive-qualified SMD package. Key features:
- Very fast switching with low reverse-recovery time (ns range)
- Forward voltage drop around 0.7–0.9 V at moderate current
- Reverse voltage rating VR typically about 75–100 V
- Forward current rating IF(AV) roughly up to 200 mA
- Low leakage and low junction capacitance for high-speed/high-frequency use
- RoHS-compliant, lead-free; Q‑7‑F indicates automotive/qualified variant
- Two-terminal SMD package suitable for compact designs
Typical applications: high-speed clipping, switching, demodulation, sampling, and general fast-switching rectification in automotive and consumer electronics. For exact electrical values, refer to the specific datasheet revision.

Package

BAV199Q-7-F uses an SOT-23 (SC-70-3) surface-mount package.

Pinout

Pin count: 3 (SOT-23-3).
Function: Dual fast-switching diodes in series (two diodes end-to-end with the junction accessible). Pin 1 = anode of D1, Pin 2 = junction between D1 and D2, Pin 3 = cathode of D2.

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor company (a spin-off from Philips/NXP) that designs and manufactures discrete semiconductors, logic devices, and MOSFETs, supplying diodes such as BAV199.
