Description

Introduction to BAV70W-QX
- A Dual High-Speed Switching Diode in one SMD package. It contains two fast diodes in a single device for compact high-frequency use.
- Key features: fast switching, low junction capacitance, low leakage, suitable for digital and RF signal paths.
- Typical applications: demodulation, clipping/limiting, level shifting, protection in logic and switching circuits, fast signal routing.
- Electrical notes (per diode): reverse voltage roughly in the tens of volts to about 70 V range; forward current in the high‑milliamp to low‑hundreds of milliamp range; low forward voltage drop.
- Package: W-series surface-mount, 3-pin layout; designed for standard reflow assembly.
- Important: exact pinout, ratings, and packaging specifics depend on the exact supplier and lot code. Check the manufacturer datasheet for BAV70W-QX for precise values and recommended operating conditions.

Equivalent

Equivalent parts for BAV70W-QX (dual high-speed switching diodes, ~70 V, SOT-23):
- BAV70W from other vendors (e.g., Nexperia, Vishay)
- BAV70 (same device from different manufacturers)
- MMBD4148W / MMBD4148 (dual high-speed diodes in SMD)
- 1N4148W (dual variant; verify footprint)
Note: always cross-check pinout, package, and voltage/current specs in the datasheets before substituting.

Features

BAV70W-QX features:
- Dual high-speed switching diodes in a single SOT-23 package (W variant)
- Reverse voltage rating VRRM = 70 V
- Very fast switching with short reverse-recovery time
- Low forward voltage drop and low junction capacitance
- Suitable for high-frequency switching, clipping, demodulation, and logic interfaces
- Pb-free, RoHS-compliant, with QX (tape-and-reel) packaging
Note: Configuration (e.g., common anode/cathode) is as per the specific datasheet variant.

Pinout

- Pin count: 3 pins (SMD package with pins 1, 2, 3).
- Function: Dual series small-signal switching diodes (D1: 1–2, D2: 2–3; current flows from pin 1 to pin 3). Used for high-speed switching, clipping/level shifting, and signal routing.
