概述

Description

BAS40-04-QR is a small, high-speed switching diode from the BAS40 family, supplied in an SMD package with the QR designation (typically RoHS/tape-and-reel). It is used for fast signal switching, level shifting, clamping, and protection in compact digital and RF circuits. Key characteristics (such as fast switching speed and low forward voltage drop) make it suitable for high-speed, low-power applications with low input capacitance. Exact electrical specs—forward current, reverse voltage, recovery time, and capacitance—depend on the specific manufacturer and variant. Always consult the manufacturer’s datasheet for BAS40-04-QR to obtain the precise values and recommended operating conditions. In short: a small, fast silicon switching diode for quick path switching in surface-mount designs; packaging and params vary by vendor.

Features

BAS40-04-QR features (concise):
- Dual Schottky barrier diodes in a compact QR package (SMD).
- Very low forward voltage drop (typ ~0.2–0.3 V), enhancing efficiency.
- Ultra-fast switching with essentially zero reverse-recovery time.
- Reverse voltage rating VRRM = 40 V.
- Forward current rating IF(AV) ≈ 200 mA.
- Low leakage current; suitable for clamping and protection.
- Wide operating temperature: −55°C to +125°C.
- Pb-free, RoHS compliant; suitable for tape-and-reel packaging.
- Ideal for high-speed switching, rectification, OR-ing, and signal-level clamping.

Package

Package type: BAS40-04-QR uses a SOT-23-3 (small 3-pin) surface-mount package. The “-QR” suffix typically denotes Tape & Reel packaging.

Pinout

- Pin count: 3 pins (SOT-23)
- Function: BAS40-04-QR is a dual fast-switching diode package, typically two diodes in series with a common node (used for high-speed switching/level-shifting).

Manufacturer

Manufacturer: Nexperia.
Nexperia is a global semiconductor company that designs and manufactures discrete devices (such as diodes and transistors), logic components, and related power/signal semiconductors for automotive and consumer electronics.

Application

Applications of BAS40‑04‑QR:
- Fast switching in logic and timing circuits
- RF/IF demodulation and envelope detection
- Clipping/limiting and input protection for sensitive signals
- Peak detectors and low-current rectifiers
- Level shifting and waveform shaping in MCU interfaces and ADC/DAC front ends

Equivalent

BAS40-04-QR is a dual fast-switching diode in SOT-23. Common cross-ref equivalents (SMD) include:
- BAV99 (dual fast-switching diode, SOT-23)
- MMBD4148DW/DM (dual fast diode, SOT-23)
Note: pinout/orientation varies by manufacturer, so verify the exact configuration (dual diodes in series vs. common anode/cathode) before substituting.
