1.5KE18 Description

Short technical summary and product information.

The Littelfuse 1.5KE18 is a unidirectional TVS diode from the 1.5KE series, designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 15.3V and a maximum clamping voltage of 26.46V at a peak pulse current of 60.3A (10/1000µs waveform). With a peak pulse power dissipation of 1500W, it provides robust protection for I/O interfaces, VCC buses, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic applications.

 

This device has a glass passivated chip junction in a DO-201 (DO-201AA, DO-27, Axial) through-hole package. It offers fast response time typically less than 1.0ps and low incremental surge resistance. The operating junction temperature range is -55°C to 175°C, with a steady state power dissipation of 6.5W at TL=75°C. It is RoHS compliant, halogen free, and lead-free (Pb-free E3).
