600 W peak pulse, 34.2 V breakdown — what this Zener does
The STMicroelectronics P6KE36ARL is a 600 W peak-pulse-power Zener diode from the P6KE TRANSIL™ series, designed for general-purpose transient overvoltage clamping. It offers a minimum breakdown voltage of 34.2 V and a maximum clamping voltage of 64.3 V at the peak pulse current of 62 A (8/20 µs waveform), with a reverse standoff of 31 V. Packaged in a DO-15 axial-lead through-hole body, it is a unidirectional single-channel device.
Buyers should plan for a one-time purchase or identify a validated alternate for production continuity.
Key ratings and the decisions they drive
The 34.2 V minimum breakdown voltage sets the threshold at which the diode begins to conduct; the circuit designer uses this to guarantee the protected node does not see more than 64.3 V clamping under the rated 600 W pulse. The 62 A peak pulse current rating (8/20 µs waveform) tells you the diode can shunt a substantial surge without failing. The 950 pF capacitance at 1 MHz matters for high-speed signal lines.
