600 W bidirectional transient suppressor, 33.3 V standoff
The P6KE39CA-T: Its 33.3 V reverse standoff voltage places it on 24 VDC or 28 VDC rails where the nominal bus sits below the clamping threshold and the TVS only conducts during a transient event.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the P6KE39CA-T as obsolete. For BOM lines that already carry this part, the supply path runs through independent surplus and broker inventory — each lot is traceable and confirmed genuine at the RFQ stage.
Temperature range and mounting
The junction temperature range spans -55°C to +175°C, covering industrial and some military-grade ambient conditions. The through-hole axial package (DO-15) is hand-solderable and rework-friendly, though the Tape & Reel packaging suggests the original procurement was for automated insertion — the reel quantity is a logistics detail, not a functional limit.
