The 1.5KE18A-T is a robust transient voltage suppression (TVS) diode designed by Diodes Incorporated to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is a part of the 1.5KE series, which is well-known for its reliability and efficiency in circuit protection.

Key Features:

• Transient Protection: The 1.5KE18A-T can clamp transient overvoltages and dissipate the energy with its peak pulse power dissipation of 1500 Watts (1.5KW) at 10/1000μs waveform, which is a standard transient threat profile.
• Breakdown Voltage: It has a stand-off voltage of 15.3 volts, with a minimum breakdown voltage of 17.1 volts, ensuring it can withstand significant voltage spikes without damage.
• Unidirectional Protection: As a unidirectional TVS diode, the 1.5KE18A-T is specifically designed to protect from overvoltages that occur in one polarity, making it ideal for DC power supply applications.
• RoHS Compliant: The product meets the Restriction of Hazardous Substances (RoHS) directive, making it suitable for use in environmentally sensitive applications.
• DO-201 Package: Encased in a molded plastic over glass passivated junction, the 1.5KE18A-T comes in a DO-201 package, which is recognized for its flame retardant capability and high-temperature soldering guaranteed at 260°C/10 seconds at terminals.

Applications:

The 1.5KE18A-T is primarily used to protect voltage sensitive components which can be found in a variety of applications such as:

• Industrial systems
• Consumer electronics
• Automotive systems
• Telecommunication devices
• Power supply units

Specification Summary:

With its combination of features, the 1.5KE18A-T is an excellent choice for designers looking to enhance the durability and longevity of their electronic systems against voltage transients.
