Product details

1.5kW bidirectional TVS for general-purpose clamping

The 1.5KE7.5C-E3/73: The bidirectional configuration (one channel) means it protects signal or power lines that swing both positive and negative relative to ground — no polarity concern during installation.

Breakdown and clamping window

Breakdown voltage starts at 6.75 V min, so the device remains non-conductive below that threshold. The DO-201AA axial-lead package (through-hole) suits point-to-point wiring on terminal strips or PCB mounting with adequate copper pad area for heat sinking.

Lifecycle reality — obsolete, sourced per RFQ

Vishay lists the 1.5KE7.5C-/73 as obsolete. For a BOM line that requires this exact clamping voltage and bidirectional footprint, the only sourcing path is the secondary market. Confirm the required quantity and acceptable date-code window when requesting a quote.
