1.5KE220CA Description

Short technical summary and product information.

The 1.5KE220CA is a transient voltage suppression (TVS) diode from Littelfuse's 1.5KE series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The device offers a peak pulse power dissipation of 1500W (10/1000µs waveform) and a peak pulse current of 4.6A. With a reverse standoff voltage of 185V and a maximum clamping voltage of 328V, it is suitable for applications requiring robust overvoltage protection. The 1.5KE220CA features a glass passivated chip junction in a DO-201 package, providing fast response time (less than 1ps) and excellent clamping capability. It is capable of operating over a wide temperature range of -55°C to 175°C. The device is RoHS compliant and halogen free, with matte tin lead-free plating. Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
