概述

Description

BAV70-QR is a dual high-speed switching diode in a compact SMD package. It contains two diodes connected in series via a common junction, giving a 3-lead device suitable for fast signal paths. Common uses include fast switching, level shifting, clipping/limiting networks, demodulation, and pulse circuits in RF and digital analog circuits. Key benefits are fast switching (short reverse-recovery), relatively low junction capacitance, and moderate current handling. The exact electrical specs vary by vendor, but the BAV70 family typically offers a reverse-voltage rating around tens of volts to about 70 V and forward current in the tens to hundreds of milliamps range per diode. The “-QR” suffix denotes a particular packaging/marking variant. For precise parameters (VR, IF, VF, Cj, trr), consult the specific BAV70-QR datasheet from the supplier.

Features

BAV70-QR Features:
- Dual high-speed switching diodes in a single SOT-23 package (QR)
- Very fast switching with low reverse-recovery time
- Low forward voltage drop and low junction capacitance
- Small-signal device suitable for high-frequency applications and signal routing
- Tape-and-reel packaging for automated assembly
- Suitable for clipping, demodulation, level shifting, and logic-gate type circuits
Note: Check the datasheet for exact pinout (common anode/cathode configuration) and electrical ratings.

Package

SC-70-3 (SC-70) 3-pin surface-mount package.

Pinout

3 pins. It is a dual high-speed switching diode pair in one package (two diodes in a single BAV70-QR device).

Manufacturer

The BAV70-QR is manufactured by Diodes Incorporated. Diodes Incorporated is a global semiconductor company that designs and supplies discrete semiconductor devices, logic and analog integrated circuits (including small-signal switching diodes like the BAV70).

Application
