STMicroelectronics P6KE18CA TVS Diode

The P6KE18CA is a high-quality Transient Voltage Suppressor (TVS) diode manufactured by STMicroelectronics, designed to protect sensitive electronic equipment from voltage spikes and surges. This TVS diode is specifically engineered to safeguard circuits against transient overvoltage events such as electrostatic discharge (ESD), electrical fast transients (EFT), and secondary lightning effects.

Key Features

• Bi-directional Surge Protection: The P6KE18CA provides bidirectional clamping and is capable of protecting circuits in both positive and negative voltage transients, making it a versatile choice for various applications.
• Peak Pulse Power: It can handle a peak pulse power dissipation of 600 Watts at 10/1000μs waveform, ensuring a high level of protection for electronic components that might be exposed to sudden voltage surges.
• Stand-off Voltage: The device has a stand-off voltage of 15.3 Volts, which is the maximum reverse voltage that can be applied without causing the diode to conduct in reverse.
• Breakdown Voltage: Its breakdown voltage ranges from 17.1 Volts to 18.9 Volts, which indicates the voltage at which the diode begins to conduct in the avalanche region.
• Low Clamping Voltage: The clamping voltage is 29.2 Volts, which is the maximum voltage drop across the diode when subjected to a peak impulse current.
• Fast Response Time: The P6KE18CA boasts an exceptionally fast response time, typically in the picosecond range, providing immediate protection against transient overvoltages.
• DO-15 Package: Housed in a molded plastic DO-15 package, it offers a compact form factor that is suitable for through-hole mounting, making it easy to integrate into a wide range of PCB layouts.

Applications

The P6KE18CA is ideal for a multitude of applications where voltage surge protection is critical. These include:

• Consumer electronics such as TVs, computers, and gaming systems
• Telecommunication systems and networking equipment
• Industrial control systems and PLCs
• Automotive electronics and safety systems
• Power supply units and voltage regulators

With its robust design and reliable performance, the P6KE18CA from STMicroelectronics is an excellent choice for engineers looking to enhance the durability and longevity of their electronic designs against harsh electrical transients.
