Littelfuse 1-Element Bi-Directional TVS Diode 1.5 kW, 2-Pin DO-201 1.5KE36CA

Littelfuse 1.5KE36CA is a 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed specifically to protect sensitive electronic equipment from voltage transients such as lightning-induced surges and other transient voltage events. It offers a peak pulse power capability of 1500 W using a 10/1000 µs waveform with a repetition rate duty cycle of 0.01%.

This diode employs a glass passivated chip junction housed in a compact DO-201 through-hole package, facilitating easy mounting on printed circuit boards. The device delivers a minimum breakdown voltage (Vbr) of 34.2 V, a maximum reverse stand-off voltage (Vwm) of 30.8 V, and a clamping voltage (Vc) of 49.9 V, providing strong transient surge protection while maintaining equipment safety.

The device can handle a maximum peak pulse current (Ippm) of 30.5 A and withstands test currents of 1 mA. Its operating temperature ranges from -55°C to 175°C, ensuring performance stability under a wide range of ambient conditions. The Littelfuse 1.5KE36CA features an exceptionally fast response time, typically less than 1.0 picosecond, for efficient suppression of transient voltages.

The plastic package is flammability rated V-0 according to Underwriters Laboratories standards, and the diode has matte tin lead-free plating (Pb-free E3 compliant), supporting environmental safety regulations. With a length of 9.5 mm and a diameter of 5.3 mm, it is a compact solution for transient voltage suppression in industrial, automotive, telecommunications, and other electronic applications.
