ON Semiconductor 1SMA11AT3 Series TVS Diodes

The 1SMA11AT3 series from ON Semiconductor represents a robust line of Transient Voltage Suppressor (TVS) diodes designed to protect voltage-sensitive components from destructive voltage spikes and transient events. This series is particularly well-suited for the safeguarding of integrated circuits, MOSFETs, signal lines, and other electronic parts that are susceptible to electrostatic discharges and other transient voltage occurrences.

Key Features

• Peak Pulse Power: The 1SMA11AT3 series offers excellent clamping capability with a peak pulse power of 400 Watts for 10/1000μs waveform, ensuring reliable protection against high energy transients.
• Stand-Off Voltage: With a stand-off voltage of 11V, this TVS diode series is optimized to prevent overvoltage conditions by clamping excess transient voltages and dissipating them as heat.
• Unidirectional Protection: These diodes offer unidirectional protection, making them ideal for DC voltage circuits where the polarity is fixed and only one direction of current flow is necessary.
• Low Leakage Current: The 1SMA11AT3 series is engineered with a low leakage current, minimizing power loss and ensuring energy efficiency in standby mode.
• Fast Response Time: These TVS diodes boast an extremely fast response time to transient events, typically in the picosecond range, providing immediate protection upon detection of a voltage spike.
• Compact Package: Housed in the SMA package, these diodes offer a compact footprint, making them suitable for space-constrained applications.
