STMicroelectronics 1-Element Bi-Directional TVS Diode 600 W, 2-Pin DO-15 P6KE12CA

STMicroelectronics P6KE12CA is a 1-element bi-directional transient voltage suppressor (TVS) diode designed for industrial-grade protection of sensitive electronic components against voltage spikes and surges.

This diode is configured as a single element with a bi-directional transient voltage suppression capability, ensuring reliable and rapid response to transient overvoltage events in both AC and DC circuits. The P6KE12CA model supports a peak pulse power dissipation rating of 600 watts, allowing it to absorb substantial transient surges without damage.

The device features a minimum breakdown voltage of 11.4 volts and a maximum reverse stand-off voltage of 10.2 volts, enabling effective clamping at voltages above normal operation to protect downstream circuits. Its clamping voltage is rated at 21.7 volts, providing a balance between protection sensitivity and operational durability.

Mechanically, the diode is housed in a DO-15 through-hole package measuring 6.75 mm in length and 3.53 mm in diameter, suitable for conventional PCB mounting methods. It accommodates 2 pins and operates effectively between -65°C and 175°C, rendering it suitable for use in demanding industrial, automotive, and commercial electronics environments.

This TVS diode ensures minimal leakage currents up to 5 microamperes, preserving energy efficiency when not in active suppression mode. The robust maximum peak pulse current rating of 184 amps guarantees dependable performance against high-energy transient events such as lightning surges or inductive load switching.

Typical applications for the P6KE12CA include industrial machinery protection, power supply surge protection, telecommunications equipment safeguard, and automotive electronics where bi-directional voltage spike mitigation is critical.
