The SMAJ17A TVS Diode from RUILON is a high-reliability 400W transient voltage suppressor designed to protect sensitive electronic circuits from electrostatic discharge (ESD), lightning-induced surges, and fast transient voltage events. Utilizing advanced avalanche breakdown technology, this device provides ultra-fast response time and precise clamping capability, ensuring effective suppression of voltage spikes and protection of sensitive semiconductor components.
With a reverse standoff voltage of 17V, the SMAJ17A is ideal for low-voltage electronic systems that require robust protection for logic-level and power interface circuits. It features low leakage current and optimized clamping performance, enabling efficient energy absorption while maintaining stable circuit operation. The diode also offers low forward voltage drop (VF), improving system efficiency and reducing power loss during transient conditions.
Encased in a durable SMA (DO-214AC) surface-mount package, the SMAJ17A ensures excellent thermal performance and mechanical reliability, making it suitable for demanding PCB applications. Its compact footprint supports automated SMT assembly while delivering strong surge handling capability.
Compared to standard protection devices, this TVS diode offers enhanced surge absorption performance, making it a dependable solution for industrial electronics, consumer devices, and communication systems requiring compact and efficient ESD protection.
