What the 600 W peak pulse rating means for your protection design
The P6KE75CA-T: At 64.1 V reverse standoff voltage it remains transparent to the protected line; when a transient exceeds 71.3 V (minimum breakdown), it clamps to 103 V maximum at 5.8 A peak pulse current. The bidirectional channel means a single device guards both polarities — useful on AC signal lines or DC rails where reverse transients are possible. The DO-204AC (DO-15) axial-lead package is through-hole mounted, suited for point-to-point wiring or PCB insertion where the lead bend radius is controlled to avoid stress on the glass passivation.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the P6KE75CA-T as obsolete. The Tape & Reel packaging (TR suffix) suits automated assembly but the axial form factor also allows hand-placement for prototype or rework.
