1.5KE7.5A Description

Short technical summary and product information.

The 1.5KE7.5A is a transient voltage suppression (TVS) diode from Littelfuse, part of the 1.5KE series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events.

 

Key electrical specifications include a reverse standoff voltage of 6.4V, a clamping voltage of 11.3V at a peak pulse current of 134.5A, and a peak pulse power dissipation of 1500W (10/1000µs waveform). The device features a fast response time of less than 1.0ps from 0V to breakdown voltage and low incremental surge resistance.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The diode is glass passivated with a junction temperature range of -55°C to 175°C and thermal resistance of 15°C/W junction-to-lead.

 

The 1.5KE7.5A is available in a through-hole DO-201AA, DO-27, or Axial package with matte tin terminal finish. It is RoHS3 compliant, halogen free, and has a flammability rating of V-0 per UL standards.
