The 1.5KE51CA-B: At that condition the clamping voltage holds at 70.1 V max while the device absorbs 21.4 A peak pulse current. For a 24 VDC bus with a 43.6 V reverse standoff, this part triggers breakdown at 48.5 V min, clamping transients before they reach downstream silicon.
Diodes Incorporated lists the 1.5KE51CA-B as obsolete.
The 1.5KE51CA-B is obsolete but available through independent distribution.
