ONSEMI SZNUP2105L ESD Protection Diode, 24V, 350W, SOT-23

The ONSEMI SZNUP2105L is a high-performance bidirectional ESD protection diode engineered to safeguard CAN transceivers in high-speed and fault-tolerant automotive and industrial networks from damaging transient voltage events, including electrostatic discharge (ESD).

This device integrates protection for both data lines into a single, compact SOT-23 package, offering system designers a cost-effective solution to significantly enhance overall system reliability and meet rigorous electromagnetic interference (EMI) compliance standards. Its advanced design ensures critical data integrity in demanding applications.

Key Features & Benefits

• Robust Protection: Offers a high 350W peak power dissipation per line (8/20 µs waveform) to absorb substantial transient energy.
• Signal Integrity: Features low capacitance and a low reverse leakage current (typically < 100 nA), minimising signal distortion and power loss, which is essential for maintaining high-speed CAN data rates.
• Comprehensive Compliance: Meets stringent automotive standards, including ISO 7637-2 and ISO 7637-3 for repetitive load switching and fast transient immunity, and carries a UL 94 V-0 flammability rating.
• Automotive Grade: The ‘SZ’ prefix denotes devices qualified to AEC-Q101 standards and capable of supporting Production Part Approval Process (PPAP) documentation, making them ideal for automotive and other critical applications.
• Environmental Responsibility: These components are manufactured to be lead-free (Pb-Free), halogen-free/BFR-free, and are fully compliant with the RoHS directive.

With its compact form factor and robust protection characteristics, the SZNUP2105L is a reliable choice for enhancing the durability and performance of sensitive electronic systems against voltage surges and ESD.
