1.5KE440CA Description

Short technical summary and product information.

The 1.5KE440CA is a bidirectional transient voltage suppression (TVS) diode from Littelfuse Inc., part of the 1.5KE series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. The device offers a peak pulse power dissipation of 1500W (10/1000μs waveform) and a clamping voltage of 602V. It utilizes Zener technology with a glass passivated chip junction for reliability.

 

Key electrical characteristics include a peak pulse current of 2.5A, a fast response time of less than 1ps from 0V to breakdown voltage, and an ESD rating of 30kV (air and contact) per IEC 61000-4-2. The operating junction temperature range is -55°C to 175°C. The diode is bidirectional with a single channel, making it suitable for AC line protection.

 

The device is packaged in a DO-201AA/DO-27 axial leaded package with through-hole mounting. It is RoHS3 compliant, lead-free (Pb-free E3), and halogen-free. Typical applications include general purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
