When a transient exceeds the 136V minimum breakdown voltage, the device clamps at a maximum 215V (at 7A peak pulse current, 10/1000µs waveform). That 215V clamp ceiling protects downstream semiconductors rated for 250V or higher — a common margin for 120V automotive bus systems. The single bidirectional channel handles symmetrical clamping for AC-coupled or floating lines. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE150CHE3/73 mounts through-hole. The axial body suits point-to-point wiring, terminal strips, or PCB layouts where the lead bend radius is controlled to avoid stress on the glass passivation. Supplied in Tape & Box (TB) format — the '73' suffix identifies this packaging variant. For hand-placement or low-volume rework, the boxed quantity avoids the handling issues of tape-and-reel cut strips. Vishay lists the 1.5KE150CHE3/73 as Obsolete. No official successor order code is recorded from the manufacturer. For a BOM line that requires this exact AEC-Q101 grade and 1500W rating, the 1.5KE150CHE3/73 remains the correct order code.","metaTitle":"Vishay 1.5KE150CHE3/73 TVS Diode, 1500W, 215V Clamp","metaDescription":"Vishay 1.5KE150CHE3/73 automotive AEC-Q101 TVS diode, 1500W peak pulse, 121V standoff, 215V clamp.
