1.5KE350A Description

Short technical summary and product information.

The 1.5KE350A is a unidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a reverse standoff voltage of 300V and a maximum clamping voltage of 482V at a peak pulse current of 3.2A (10/1000µs waveform).

 

With a peak pulse power dissipation of 1500W (10/1000µs), this device offers robust transient protection for general purpose applications. The glass passivated chip junction ensures reliable performance, and the fast response time (typically less than 1.0ps from 0V to breakdown voltage) provides rapid clamping of overvoltage events.

 

The 1.5KE350A is housed in a DO-201AA, DO-27, or Axial through-hole package (supplier device package DO-201) and operates over a junction temperature range of -55°C to 175°C. It is halogen free and RoHS compliant, with Pb-free E2 second level interconnect.
