Littelfuse 1-Element Bi-Directional TVS Diode, 1.5 kW Peak Pulse Power, 2-Pin DO-201 Package 1.5KE56CA-B

Littelfuse 1.5KE56CA-B is a single element bi-directional TVS diode designed for transient voltage suppression with a peak pulse power dissipation capability of 1.5 kW. It features a 2-pin DO-201 package with through-hole mount configuration, making it suitable for robust and reliable circuit protection in industrial and electronic applications.

This diode provides protection against voltage spikes and surges, with a minimum breakdown voltage of 53.2V and a maximum reverse stand-off voltage of 47.8V. The clamping voltage of 77V ensures effective voltage spike limitation, safeguarding sensitive components in power lines and signal circuits.

Its maximum peak pulse current rating is 19.7A, which allows it to absorb large transient currents. Operating efficiently within a temperature range of -55°C to 175°C, this diode is ideal for harsh industrial, manufacturing, and electronic environments. The physical dimensions of 9.5mm length and 5.3mm diameter allow easy integration into through-hole PCB designs.

Equipped with electrostatic discharge (ESD) protection, the 1.5KE56CA-B helps to enhance device and system reliability. The single element per chip construction ensures precise clamping characteristics and consistent performance.

Typical applications include power supplies, power strips, telecom equipment, automotive electronics (non-automotive certified), and industrial electrical circuits requiring reliable transient voltage suppression.
