600W bidirectional TVS for 13V rails
The STMicroelectronics P6KE15CARL is a bidirectional transient voltage suppression diode from the P6KE TRANSIL™ series, rated for 600W peak pulse power over a 10/1000µs waveform. It provides clamping at 27.2V maximum when the surge current hits 147A (8/20µs pulse), with a reverse standoff voltage of 13V. This makes it a fit for protecting 12V or 13V DC rails, signal lines, and general-purpose board-level interfaces where a through-hole axial package is acceptable.
The P6KE15CARL carries an Obsolete lifecycle status from STMicroelectronics.
The 27.2V maximum clamping voltage at Ipp sets the upper limit the downstream circuitry sees during a surge — a 13V rail device rated for 30V absolute maximum has comfortable margin. The 950pF typical capacitance at 1MHz is moderate; it adds about 150Ω of reactive loading at 1MHz signal lines, which is fine for power rails or low-speed I/O but may distort fast digital edges above a few MHz. For high-speed data lines (Ethernet, USB), a lower-capacitance TVS (under 5pF) would be preferred.
