Littelfuse 1-Element Bi-Directional TVS Diode 1500 W, 2-Pin DO-214AB Package 1.5SMC440CA

The Littelfuse 1.5SMC440CA is a 1-Element Bi-Directional Transient Voltage Suppressor (TVS) diode designed to protect electronic circuits from voltage spikes. It features a peak pulse power dissipation rating of 1500 W, making it ideal for safeguarding sensitive electronics against transient voltage events.

This device uses a single diode configuration with bi-directional direction type, which allows it to clamp voltage from both positive and negative surges effectively. It is packaged in a compact DO-214AB (SMC) surface mount package, facilitating easy and reliable PCB mounting in modern electronic assemblies.

Key electrical specifications include a minimum breakdown voltage of 418 V and a maximum reverse stand-off voltage of 376 V. The clamping voltage of 602 V ensures the diode activates promptly to prevent damage to downstream components. It can conduct a maximum peak pulse current of 2.5 A during transient events while maintaining very low reverse leakage current of 1 μA under normal operation, enhancing circuit longevity.

It is suitable for extended operating temperatures ranging from -65°C to 150°C, which supports reliability in harsh industrial or commercial environments. The device dimensions are 7.11 mm (length), 6.22 mm (width), and 2.417 mm (height), offering a compact footprint for space-constrained designs.

This TVS diode meets ESD protection requirements, though it does not have specific automotive certification.

Applications span across electronic component protection in industrial control, power supplies, consumer electronics, and telecommunications equipment. Its bi-directional voltage clamping makes it suitable for AC and DC signal lines, ensuring comprehensive voltage transient suppression.
