Its 26 V reverse standoff voltage means it sits across a 24 V rail without conducting during normal operation, while the 28.5 V minimum breakdown voltage defines where clamping begins. When a transient hits, the device clamps at 53.5 V maximum and can handle 75 A of peak pulse current under the 8/20 µs waveform — enough for industrial surge events on DC power buses or relay-coil kickback. The 1075 pF capacitance at 1 MHz is worth noting for signal-line applications — this is a power-rail suppressor, not a high-speed data-line protector. On a 24 VDC motor-drive rail or a 24 V industrial sensor bus, the capacitance is irrelevant; on a communication line above a few hundred kHz, it would load the signal. The part carries no power-line protection rating, confirming its role as a secondary-side transient clamp rather than a mains-entry suppressor. ## DO-15 axial package — through-hole assembly considerations The P6KE30ARL comes in a DO-204AC (DO-15) axial-lead package, intended for through-hole mounting. This is a hand-solder or wave-solder form factor — not pick-and-place friendly without a forming fixture. The Tape & Reel suffix (RL) means it ships on a reel for automated lead-forming equipment, not for SMD placement. If your rework bench or prototype lab needs a few pieces for a repair, the axial leads are easy to hand-solder into plated through-holes, but verify the lead bend radius matches your hole spacing. ## Obsolete — sourcing through independent distribution The P6KE30ARL is listed as Obsolete by STMicroelectronics. For a BOM line that calls out this exact ordering code, the procurement path is independent distribution, where we source from verified inventory lots. Because this is a through-hole Zener from a mature family, date codes on the surplus market can span several years.","metaTitle":"STMicroelectronics P6KE30ARL TRANSIL Zener, 600W DO-15","metaDescription":"P6KE30ARL is a 600W TRANSIL Zener diode in DO-15 axial package, 26V standoff, 53.5V clamp.

For a drop-in functional replacement, any P6KE30A variant from the same TRANSIL family with a 26 V standoff and DO-15 package will match the electrical specifications. Verify the breakdown voltage tolerance and clamping voltage match your design margin before substituting."},{"question":"Can P6KE30A replace P6KE30ARL?","answer":"Yes, electrically the P6KE30A is identical — same 26 V standoff, 28.5 V breakdown, 53.5 V clamp, 600 W rating. The difference is packaging: P6KE30ARL ships on Tape & Reel for automated lead forming, while P6KE30A ships in bulk or tube. For hand-assembly or prototype work, the P6KE30A is a direct substitute. For automated through-hole insertion that expects reel-fed parts, verify your feeder compatibility."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/P6KE30ARL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/P6KE30ARL when reusing this data.
