Product Description
STMicroelectronics 1.5KE39CA is a high-performance single-element bi-directional Transient Voltage Suppressor (TVS) diode capable of dissipating peak pulse power of 1.5 kW. Packaged in a DO-201 axial through-hole form factor, it provides reliable clamp voltage performance and protection against voltage transients in sensitive electronic circuits.
This device offers a minimum breakdown voltage of 37.1 volts and a maximum reverse stand-off voltage of 33.3 volts, ensuring strong suppression of voltage spikes up to 69.7 volts clamping voltage. It safely conducts peak pulse currents up to 143 amps without damage, enabling effective protection against lightning surges and other transient events.
Designed for harsh industrial environments, the 1.5KE39CA operates within a wide temperature range from -65°C to 175°C. The maximum reverse leakage current is minimal at 1 microampere, contributing to energy efficiency and device longevity.
Its robust DO-201 package measures approximately 5.3 mm in diameter, width, and height, with a length of 9.5 mm, making it suitable for through-hole PCB applications in electronic and electrical equipment.
Single diode configuration and bi-directional operation for comprehensive transient protection. Peak pulse power dissipation rating of 1.5 kW for high energy absorption. Wide operating temperature range from -65°C to 175°C for reliability.
Compact axial DO-201 package enables easy integration in various electronic assemblies. Low leakage current reduces power loss and heat generation in circuits.
This TVS Diode is ideal for use in a broad spectrum of industrial, electronic, and electrical applications where protection from voltage transients is critical, including power supplies, communication devices, and automotive electronics. STMicroelectronics ensures product quality and reliability with consistent manufacturing standards.
