Product Description
STMicroelectronics 1.5KE18A is a uni-directional Transient Voltage Suppressor (TVS) diode engineered to provide robust protection to electronic circuits against transient voltage spikes. It offers a peak pulse power dissipation rating of 1.5 kW and features a single element diode configuration housed in a compact 2-pin axial DO-201 package.
This diode is designed for through-hole mounting, simplifying integration into printed circuit boards (PCBs) in industrial, electronic, and electrical applications. The device operates efficiently across a broad temperature range from -65°C to 175°C, suitable for rugged environments.
With a minimum breakdown voltage of 17.1 V and maximum reverse stand-off voltage of 15.3 V, it provides reliable voltage threshold protection. The diode can handle transient peak currents up to 308 A, affording strong spike suppression. Its low maximum reverse leakage current of 1 μA ensures minimal power loss during normal operation.
The diode's clamping voltage is approximately 32.5 V, limiting voltage surges that could damage sensitive components. Its dimension specs include 9.5 mm length and 5.3 mm diameter, making it suitable for compact electronic assemblies.
This TVS diode is ideal for industrial, manufacturing, power supply protection, and electronic system safeguarding applications. It ensures enhanced circuit reliability by rapidly clamping excessive voltages caused by electrostatic discharge (ESD) or electrical transient events.
Provides 1.5 kW peak pulse power transient voltage suppression. Uni-directional single element diode configuration. Through-hole mounting in DO-201 axial package. Broad operating temperature range of -65°C to +175°C. Low leakage current of 1 μA maximizes efficiency.
Compact size: 9.5 mm length and 5.3 mm diameter. Clamping voltage of 32.5 V for voltage spike limitation. Rated peak pulse current of 308 A ensures strong surge handling. Widely used in electronic manufacturing and industrial power protection systems.
