The 1.5KE51CA 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 voltage events. The device features a reverse standoff voltage of 43.6V and a clamping voltage of 70.1V at a peak pulse current of 21.7A, with a peak pulse power dissipation of 1500W (10/1000μs waveform).
This TVS diode offers fast response time of less than 1.0ps from 0V to breakdown voltage minimum, and includes ESD protection per IEC 61000-4-2 (30kV air/contact) and EFT protection per IEC 61000-4-4. It is housed in a DO-201AA/DO-27 axial leaded through-hole package, with a glass passivated chip junction for reliability. The device is RoHS compliant, halogen free, and lead-free (E3).
Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The operating junction temperature range is -55°C to 175°C, with steady state power dissipation of 6.5W on infinite heat sink.
