600 W peak pulse, 47.8 V standoff — the protection window
The P6KE56A-T: Clamping occurs at 77 V maximum when the peak pulse current reaches 7.8 A, limiting the transient voltage seen by the downstream silicon. The minimum breakdown voltage of 53.2 V ensures the avalanche region is entered before the clamp level is reached, providing a defined protection window between normal operation and full clamping.
DO-15 axial package and temperature grade
Housed in the DO-204AC (DO-15) axial-lead package, the P6KE56A-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 package outline. The operating junction temperature range spans -55°C to +175°C, covering military and industrial thermal environments without derating at the extremes.
Obsolete — sourcing through independent channels
Diodes Incorporated has classified the P6KE56A-T as obsolete. No official successor order code is recorded.
