概述

Description

BAS70-04-QR is a dual Schottky barrier diode in a compact SOT-23 package. It contains two Schottky diodes in one package with a common connection (the exact common-pin arrangement—common cathode or common anode—depends on the variant; check the datasheet for the exact pinout).
Key points:
- Very low forward voltage drop and fast switching speed, suitable for high-speed, low-voltage circuits.
- Common applications: precision rectification, demodulation, level shifting, input protection, and diode-OR/steering in power-management or RF circuits.
- Important specs to verify in the datasheet: reverse voltage (VR), forward current (IF), forward voltage (VF) at a given IF, reverse leakage (IR), and junction capacitance.
The “QR” suffix typically indicates a specific packaging/tape‑and‑reel option (and RoHS compliance) from the manufacturer. For exact electrical values and the correct pinout, consult the BAS70-04-QR datasheet from the supplier.

Features

BAS70-04-QR features (typical):
- Schottky barrier diode array (dual/quad in one package)
- Very low forward voltage drop and fast switching (suitable for high-speed/low-loss apps)
- Small surface-mount package with QR tape-and-reel packaging (RoHS compliant)
- Broad operating temperature range for harsh environments
- Low reverse leakage at normal temps
- Useful for high-speed rectification, clamping, protection, and logic-level applications
Note: exact diode count, pinout, and ratings depend on the specific BAS70-04-QR variant—consult the datasheet for precise details.

Package

Typically BAS70-04-QR is in a SC-74A/SOT-23-6 (6‑lead) surface-mount package.

Pinout

Pin count: 3 pins.
Function: BAS70-04-QR is a dual small-signal switching diode in a SC-70/SOT-323 style package with a common cathode (two anodes to separate pins, common cathode on the third). Used for fast switching/rectification in general signal paths.

Manufacturer

Manufacturer: Vishay Intertechnology, Inc. It is a global, multinational company that designs and manufactures discrete semiconductors and passive electronic components (e.g., diodes, transistors, resistors, capacitors) for a wide range of industries.

Application

BAS70-04-QR is a small-signal Schottky diode pair in an SMD package used for high-speed switching and low-loss rectification. Applications include: fast digital and RF switching, envelope detection and demodulation in communication receivers, clamping/protection of logic inputs, and low-power rectifiers in DC-DC converters and portable power supplies. It offers low forward voltage drop and fast recovery for compact electronics.
