Product details

Transient protection for 6.4 V rails

The 1.5KE7.5A A0G: The 6.4 V reverse standoff voltage means the diode draws negligible leakage below that level, so it sits across a 5 V or 6 V supply bus without loading it during normal operation.

Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE7.5A A0G mounts into a standard 0.100-inch pitch hole pattern on the PCB. The DO-201 supplier device package is the same footprint used across the 1.5KE series, so the board layout is shared with other voltage variants in the family.

Frequently asked questions

What package does 1.5KE7.5A A0G come in?

It is supplied in a DO-201AA (DO-27) axial-lead through-hole package, also referred to as the DO-201 supplier device package. It ships in Tape & Box (TB) format.
