What the 600 W peak pulse rating means for the BOM
The P6KE24A-T is a 600 W Zener TVS diode in the P6KE series from Diodes Incorporated, designed for general-purpose circuit protection against transient overvoltage events. The 22.8 V minimum breakdown voltage means the TVS starts conducting before the rail exceeds the 20.5 V standoff, protecting sensitive ICs on 24 V nominal buses.
Housed in a DO-204AC (DO-15) axial-lead package, the P6KE24A-T is a through-hole device suited for point-to-point wiring or PCB mounting where the lead bend radius and hole diameter follow the DO-15 footprint. The unidirectional channel protects a single polarity rail; for AC or bidirectional lines, two devices back-to-back or a dedicated bidirectional TVS is needed.
