Product Description

The 1SMA5913B from Littelfuse SMA Series is a high-performance TVS Diode designed for robust transient voltage suppression in demanding industrial applications. This device features a peak pulse power rating of 400 W (10/1000 μs waveform) and operates within a working voltage range of 11.2 V to 13.3 V, ensuring reliable protection for sensitive electronic circuits against voltage spikes and surges. With a breakdown voltage of 14.3 V (minimum) and a clamping voltage of 21.2 V at 16.7 A, it efficiently diverts excess energy to safeguard connected modules like power supplies, communication interfaces, or control systems. The 1SMA5913B supports a wide temperature range of -55°C to +150°C, making it suitable for automotive, telecommunications, and industrial automation environments. Its compact SMA package enables easy integration into space-constrained designs. Key advantages include fast response time (<1 ps) and high surge capacity, though its unidirectional configuration limits use in AC systems. This TVS diode does not incorporate battery capacity, display components, or proximity sensing features.
