The 1.5KE82CAHA0G: The breakdown voltage range starts at 77.9 V minimum, which sets the threshold where the device begins conducting. Below that, the 70.1 V standoff rating guarantees the diode stays in high-impedance mode during normal operation — a 72 V nominal bus with 5 % ripple stays within the safe window. At the 13.9 A peak pulse current, the clamping voltage rises to 113 V maximum. This is the voltage the protected circuit must survive; a downstream DC-DC converter with a 120 V abs-max input has margin. The 1500 W peak pulse power is the product of the clamping voltage and the peak current — a standard rating for this DO-201 package size. No power line protection is a note that this is a data-line or DC-bus suppressor, not a mains AC protector.
Package, mounting, and thermal envelope
Supplied in Tape & Box (TB) format — the axial leads are taped for automated insertion but boxed rather than reeled, which is common for through-hole parts with larger body diameters.
