DESD5V0S1BA-7

The DESD5V0S1BA-7 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed to protect sensitive electronic components from voltage spikes and transients. Here’s a detailed description of its features and specifications:

General Overview:

• Type: Unidirectional TVS Diode
• Package: Typically available in a compact SOD-323 package, which is suitable for surface mount applications.
• Function: Primarily used for ESD (Electrostatic Discharge) protection, safeguarding sensitive devices such as microcontrollers, communication ports, and other integrated circuits.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): The DESD5V0S1BA-7 has a reverse stand-off voltage of 5V, meaning it can withstand a continuous voltage of up to 5 volts without conducting.
• Clamping Voltage (V_C): Under specified surge conditions, the clamping voltage is typically around 9V, which indicates the maximum voltage that can appear across the device during a transient event.
• Peak Power Dissipation: The device can handle peak power dissipation of around 400W for a short duration (typically 8/20 µs pulse), making it effective against high-energy transients.
• Capacitance: The input capacitance is low, generally around 5pF, which minimizes signal distortion in high-speed data lines.

Performance Features:

• ESD Protection: The DESD5V0S1BA-7 is designed to meet or exceed the IEC 61000-4-2 standard for ESD protection, providing robust defense against electrostatic discharges.
• Low Leakage Current: The device exhibits low leakage current, which is crucial for battery-operated devices to prolong battery life and maintain efficiency.
• Fast Response Time: The diode responds quickly to transient events, ensuring that sensitive components are protected almost instantaneously.

Applications:

• Consumer Electronics: Ideal for protecting USB ports, HDMI interfaces, and other I/O connections in smartphones, tablets, and laptops.
• Automotive: Suitable for automotive applications where ESD protection is critical for electronic control units (ECUs) and infotainment systems.
• Industrial Equipment: Used in industrial automation systems to protect against voltage spikes from inductive loads and switching devices.

Mechanical Characteristics:

• Dimensions: The SOD-323 package is compact, typically measuring around 2.0mm x 1.25mm, making it suitable for space-constrained applications.
• Mounting: Designed for surface mount technology (SMT), facilitating automated assembly processes.

Conclusion:

The DESD5V0S1BA-7 from Diodes Incorporated is a highly effective transient voltage suppressor that combines compact size with robust performance characteristics, making it an excellent choice for protecting sensitive electronic components in a variety of applications. Its ability to handle ESD events and transient voltage spikes ensures the reliability and longevity of electronic devices.
