1.5KE18A Description

Short technical summary and product information.

The 1.5KE18A is a unidirectional Zener TVS diode designed for general purpose transient voltage suppression. It has a reverse standoff voltage of 15.3V and a clamping voltage of 32.5V at a peak pulse current of 308A (8/20µs waveform). The device can handle 1500W of peak pulse power. It features a single unidirectional channel and does not include power line protection.

 

The diode has a capacitance of 4300pF at 1MHz, which should be considered when protecting high-speed signal lines. It is mounted using through-hole technology and is available in DO-201AA, DO-27, and Axial packages. The supplier device package is DO-201.

 

This TVS diode is suitable for general purpose applications requiring reliable overvoltage protection in through-hole PCB designs.
