Obsolete — last-time-buy sourcing for sustainment programs
Diodes Incorporated has marked the P6KE8V2CA-T as Obsolete. The last-time-buy window has closed; inventory is what remains in the surplus and broker market.
600W peak pulse — what the rating means for the BOM line
This is the standard TVS power rating for the P6KE series — it defines how much transient energy the device can clamp without failing. For a 7.02V reverse standoff voltage, the 600W rating translates to a peak pulse current of 50A at the 12.1V clamping point. The breakdown voltage range starts at 7.79V minimum, meaning the device begins conducting just above the 7.02V standoff level, protecting downstream circuitry from overvoltage events. The clamping voltage of 12.1V at the rated current is the maximum voltage the protected circuit will see during a surge event. For a 5V or 3.3V logic rail, this clamping voltage is too high; the P6KE8V2CA-T is better suited for 7V nominal rails or as a secondary protector on higher-voltage buses where the 12.1V clamp is within the downstream device's absolute maximum rating.
DO-15 axial package — through-hole legacy footprint
The P6KE8V2CA-T comes in the DO-204AC (DO-15) axial-lead package, a through-hole form factor that has been a workhorse in circuit protection for decades. The axial leads are suited for point-to-point wiring, terminal block mounting, or through-hole PCB assembly.
