ESDA25SC6

ESDA25SC6 Description

The ESDA25SC6 from STMicroelectronics is a high-performance 24V unidirectional TVS diode designed for ESD (electrostatic discharge) and transient voltage protection in sensitive electronic circuits. Part of the TRANSIL™ series, it features a low clamping voltage and high peak pulse power (300W), ensuring robust protection against surges. Housed in a compact SOT23-6 package, it is optimized for surface-mount applications where board space is critical. With a reverse standoff voltage of 24V (typ) and a minimum breakdown voltage of 25V, it provides reliable overvoltage protection while maintaining low leakage current. Compliant with RoHS3 and REACH standards, it is ideal for modern electronics requiring environmental compliance.

ESDA25SC6 Features

• Unidirectional Protection: 4-channel design for safeguarding positive voltage lines.
• High Surge Handling: 300W peak pulse power (8/20µs) for robust transient suppression.
• Low Clamping Voltage: Minimizes stress on protected components.
• Compact SOT23-6 Package: Space-efficient for high-density PCB layouts.
• Fast Response Time: Reacts instantly to ESD events (IEC 61000-4-2 compliant).
• Wide Operating Range: 24V standoff voltage with a 25V minimum breakdown.
• Reliable Compliance: RoHS3, REACH Unaffected, and ECCN EAR99 certified.
• MSL 1 (Unlimited): Suitable for extended storage without moisture sensitivity concerns.

ESDA25SC6 Applications

• Consumer Electronics: USB ports, HDMI interfaces, and touchscreens in smartphones/tablets.
• Industrial Systems: PLCs, sensors, and communication modules exposed to voltage transients.
• Automotive Electronics: CAN bus, infotainment systems, and onboard diagnostics (OBD).
• Telecom/Networking: Ethernet PHYs, routers, and switches requiring IEC 61000-4-2 protection.
• Medical Devices: Portable equipment with exposed connectors (e.g., patient monitoring).

Conclusion of ESDA25SC6

The ESDA25SC6 stands out as a high-efficiency TVS diode for ESD and surge protection, combining compact size, high power handling, and multi-channel safeguarding. Its unidirectional design and low clamping voltage make it superior to generic diodes in protecting sensitive ICs.
