Product details

600 W peak pulse, 47.8 V standoff — the clamp voltage that defines the protection rail

The P6KE56A-B: The 77 V clamp means this part protects a 48 V nominal rail — common in telecom and industrial DC buses — by shunting transients before they exceed the downstream converter's absolute maximum input.

DO-15 axial — through-hole mounting for board-level transient suppression

Housed in a DO-204AC (DO-15) axial-lead package, the P6KE56A-B mounts through-hole and is supplied in Bulk — suitable for hand-assembly or wave-solder lines where surface-mount TVS may not handle the pulse energy without board-spacing constraints.

Diodes Incorporated lists the P6KE56A-B as Active (current production). The part is sourced through authorized and independent distribution channels.

Frequently asked questions

Is P6KE56A-B RoHS compliant?
