Obsolete 1.5kW bidirectional TVS — what the ratings mean for your BOM
The 1.5KE75CA_R2_00001: Its 103V maximum clamping voltage at 14.6A peak pulse current (10/1000µs waveform) defines the voltage the downstream circuitry must survive — anything rated below 103V sees the full clamp stress during a surge event.
Housed in a DO-201AE axial-lead through-hole package, the 1.5KE75CA_R2_00001 mounts with the body spaced off the board — the leads carry the heat to the solder joint and copper trace. The bidirectional construction means a single device clamps both polarities, saving a series pair in a dual-diode layout. Available on tape and reel or cut tape, the axial format feeds into automatic insertion equipment but also hand-solders cleanly for prototype or repair work.
