The through-hole body handles the thermal pulse of a 600W surge better than a comparable SMD package because the lead frame and the copper pad on the PCB sink heat directly into the board's copper pour. ## Lifecycle reality — obsolete, sourced to order Diodes Incorporated lists the P6KE400A-T as Obsolete. No pin-compatible direct replacement is documented; a functional equivalent would need to match the 342V standoff, 548V clamp, and 600W peak pulse rating in a DO-15 package.","metaTitle":"P6KE400A-T TVS Diode, 600W, 342V Standoff, DO-15","metaDescription":"Diodes Inc P6KE400A-T Zener TVS, 600W peak pulse, 342V reverse standoff, 548V clamp, DO-15 axial.
