Littelfuse Transil 1.5KE Unidirectional TVS Diode 30.8V, DO-201

The Littelfuse Transil 1.5KE series is a transient voltage suppression (TVS) diode designed to protect sensitive electronic circuits from voltage transients induced by lightning and other transient events. With a peak pulse power rating of 1500W (10/1000μs waveform) and a fast response time of less than 1ps from 0V to breakdown voltage, this diode ensures robust and reliable protection for vulnerable components.

Featuring a glass passivated chip junction and excellent clamping capability, the diode delivers superior surge protection while maintaining low incremental surge resistance. It complies with IEC-61000-4-2 ESD (30kV air and contact) and IEC 61000-4-4 EFT standards, making it ideal for data line protection in demanding environments. The diode is available in a DO-201 case with through-hole mounting and operates over a junction temperature range of -55°C to 175°C.
