Product Description
onsemi NUP3105LT1G is a 1-element bi-directional Transient Voltage Suppression (TVS) diode designed for protecting sensitive electronic circuits from electrostatic discharge (ESD) and transient voltage spikes. With a peak pulse power dissipation rating of 350 W and housed in a compact 3-pin SOT-23 surface-mount package, it is optimized for space-constrained industrial and automotive applications.
This diode features a common anode configuration suitable for bi-directional voltage spike suppression, specifically targeting CAN bus and other high-speed data lines. Its low reverse leakage current of under 100nA ensures minimal impact on normal operation, while low capacitance supports high-speed CAN data communication.
The device operates reliably over a wide temperature range from -55°C to 150°C and complies with rigorous automotive quality standards including AEC-Q101, making it suitable for harsh automotive environments.
It meets multiple international standards for transient immunity including IEC 61000-4-2 (Level 4 for ESD), IEC 61000-4-4 (Electrical Fast Transient at 40A for 5/50ns pulses), and IEC 61000-4-5 (Lightning surge at 8A with 8/20μs waveform), ensuring robust protection against transient events.
The NUP3105LT1G is widely used in smart distribution systems, industrial control networks, and fault-tolerant automotive CAN bus networks to prevent damage and data corruption caused by electrical surges and ESD events.
Provides effective bi-directional transient voltage suppression for data lines. Excellent low leakage current maintains system efficiency. Compact surface-mount SOT-23 package facilitates high-density PCB layouts. Complies with automotive and IEC transient standards for maximum reliability.
Wide operating temperature range supports demanding environments. Supports high-speed CAN data rates with low device capacitance. Ideal for harsh industrial, automotive, and smart distribution applications.
