BAV70-QR

BAV70-QR is a dual fast-switching diode in a compact surface-mount package (part of the BAV70 family). It contains two diodes in one package, typically configured in a common-anode or common-cathode arrangement depending on the variant; check the datasheet for the exact pinout.
Key points:
- Purpose: high-speed switching and signal-processing applications.
- Package and suffix: -QR denotes a RoHS-compliant, tape-and-reel SMD package suitable for automatic placement.
- Typical characteristics: fast switching times, low forward voltage, and modest forward current (per diode) with a reasonable reverse voltage rating (specified in the datasheet).
Common uses:
- High-speed clipping and shaping of digital or RF signals
- Demodulation, level shifting, and logic protection
- Small signal routing in telecom and microcontroller interfaces
Note: Always refer to the specific BAV70-QR datasheet variant for exact pinout, voltage/current ratings, and whether the dual diodes are common-anode or common-cathode.

BAV70-QR is a dual high‑speed switching diode in a small SMD package. Equivalents vary by package/pinout and ratings. Please confirm: (1) package (SC-70/SOT-23), (2) reverse voltage and forward current, (3) common-cathode or common-anode. With those, I can provide exact cross‑references from major vendors (e.g., Nexperia, Vishay, ON Semiconductor, Diodes Inc).

BAV70-QR features (concise):
- Dual high-speed switching diodes in a single SMD package (two diodes in series).
- Very fast switching suitable for high-frequency circuits.
- Reverse voltage rating: VR ≈ 70 V.
- Low forward-voltage drop (typically ~0.6–0.75 V at small forward currents).
- Low reverse leakage current.
- RoHS-compliant, QR-series packaging (typical tape-and-reel for automated assembly).
- Wide operating temperature range (generally -55 °C to +125 °C).
Applications: high-speed switching, clipping/limiting, demodulation, and signal-processing circuits.

Pin count: 3 pins (SOT-23 package).
Function: BAV70-QR is a dual series switching diode in one package; D1 (pin1 to pin2) and D2 (pin2 to pin3) form a series diode chain with a common middle node. Used for high-speed switching applications.

- Manufacturer: Nexperia.
- What kind of company: A global semiconductor company that designs and manufactures discrete devices (e.g., diodes like BAV70), MOSFETs, ESD protection, and related components. It was spun off from NXP Semiconductors and is headquartered in the Netherlands with worldwide operations.
