Product details

Surge protection for 5V and 6V rails

The 1.5KE7.5A R0G: The 6.4V reverse standoff means the diode stays off the line under normal 5V or 6V bias, only conducting when a transient pushes the rail above 7.13V breakdown.

Active production, no end-of-life risk

Taiwan Semiconductor lists the 1.5KE7.5A R0G as Active. For BOM planning, this part remains a standard catalog item — no last-time-buy pressure, no forced migration to a successor.

DO-201 axial leaded — board-fit considerations

The part is supplied in a DO-201AA / DO-27 axial-leaded through-hole package. The lead spacing and body diameter match the standard DO-201 footprint. For rework or manual insertion, the axial leads are solderable with a standard iron or wave process.
