1.5KE120A Description

Short technical summary and product information.

The 1.5KE120A is a unidirectional TVS (Transient Voltage Suppression) diode designed to protect sensitive electronic circuits from voltage transients. It offers a peak pulse power dissipation of 1500W (10/1000μs waveform) and a peak pulse current of 9.5A. The device has a Zener breakdown voltage of 165V with a tolerance of 5% (indicated by the 'A' suffix). It features a fast response time of less than 1 ps and provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2. The diode is not intended for power line protection but is suitable for general purpose applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The 1.5KE120A is packaged in a DO-201AA/DO-27 axial lead through-hole package, with an operating temperature range of -55°C to 175°C. It is RoHS3 compliant, REACH unaffected, and halogen free. The device is lead-free with Pb-free E3 termination.
