NUP4301MR6T1

NUP4301MR6T1 Description

The NUP4301MR6T1 from onsemi is a general-purpose TVS (Transient Voltage Suppression) diode designed for surface-mount applications. Packaged in SC-74 (SOT-457), it features four unidirectional channels with a rail-to-rail steering configuration, offering robust protection against transient voltage spikes. With a minimum breakdown voltage of 70V and a low capacitance of 1.6pF @ 1MHz, it ensures minimal signal distortion in high-speed circuits. This device is RoHS-compliant, REACH-unaffected, and classified under ECCN EAR99, making it suitable for global deployments.

NUP4301MR6T1 Features

• Steering Diode Configuration: Rail-to-rail topology for bidirectional transient suppression.
• Low Capacitance (1.6pF @ 1MHz): Ideal for high-speed data lines (USB, HDMI, Ethernet).
• High Breakdown Voltage (70V Min): Reliable protection against ESD and surge events.
• Compact SC-74 Package: Space-efficient for dense PCB layouts.
• Unidirectional Channels (4): Protects multiple I/O lines simultaneously.
• Moisture Sensitivity Level (MSL 1): Suitable for extended storage and handling.

NUP4301MR6T1 Applications

• Consumer Electronics: ESD protection for USB ports, displays, and touch interfaces.
• Telecommunications: Safeguarding high-speed data lines (PCIe, LVDS).
• Industrial Systems: Robust transient suppression in PLCs and sensors.
• Automotive Infotainment: Protection for CAN bus and infotainment interfaces.
• Medical Devices: Ensuring signal integrity in sensitive diagnostic equipment.

Conclusion of NUP4301MR6T1

The NUP4301MR6T1 excels in high-speed, multi-channel transient protection with its low capacitance and high breakdown voltage. While marked as obsolete, its SC-74 package and rail-to-rail steering make it a legacy solution for designs requiring compact, reliable ESD protection. Engineers should verify availability but can leverage its performance in data-line protection, industrial controls, and portable electronics where signal integrity is critical.
