Product Description

The 1SMA5931B TVS Diode is a high-performance transient voltage suppressor designed to protect sensitive electronic circuits from voltage surges and transients. This SMA5931B Surge Protector operates within a wide voltage range of 5V to 36V, offering a peak pulse power dissipation of 400W. It features a low clamping voltage and fast response time, making it ideal for direct integration into circuits requiring robust overvoltage protection. Compatible with automotive, industrial control, and communication systems, the Transient Voltage Suppressor Diode supports operating temperatures from -55°C to +150°C. Its compact SMA package ensures easy installation in space-constrained environments. Advantages include high reliability and minimal leakage current, though thermal management may require attention in high-frequency applications. As a passive component, it does not incorporate battery capacity, screen interfaces, or active sensing capabilities.
