DG403BDJ Description

The DG403BDJ is a through-hole mounted, quad single-pole single-throw (SPST) analog switch designed by Vishay Siliconix. This obsolete component offers a robust set of features suitable for a variety of applications requiring reliable switching performance. The DG403BDJ is housed in a tube package and features a 1:1 multiplexer/demultiplexer circuit configuration. It supports a wide supply voltage range, with dual supply voltages of ±7V to ±22V and single supply voltages of 13V to 36V. This flexibility makes it suitable for different power supply configurations.

DG403BDJ Features

• Low Leakage Current: The DG403BDJ boasts a maximum leakage current (IS(off)) of 500pA, ensuring minimal power loss and high efficiency in applications where low leakage is critical.
• Low On-State Resistance: With a maximum on-state resistance (R(on)) of 45Ω, the DG403BDJ ensures minimal voltage drop across the switch when it is in the on state, leading to high signal integrity and reduced power dissipation.
• Fast Switching Times: The switch time (Ton, Toff) is a maximum of 150ns and 100ns respectively, allowing for rapid switching between states, which is essential for high-speed applications.
• Low Channel Capacitance: Both the source-to-drain (CD(off)) and source-to-gate (CS(off)) capacitances are 12pF, minimizing signal distortion and ensuring high performance in analog signal processing.
• Minimal Charge Injection: The DG403BDJ has a charge injection of 60pC, which helps in maintaining signal purity and reducing transient effects during switching.
• Moisture Sensitivity Level (MSL): The MSL rating of 1 (Unlimited) indicates that the component is highly resistant to moisture, making it suitable for use in a wide range of environmental conditions.
• Compliance: The DG403BDJ is REACH unaffected, ensuring compliance with environmental and safety regulations.
