Product details

Peak pulse power and clamping for a 6.4 V rail

The 1.5KE7.5: The 6.75 V minimum breakdown voltage gives the designer a window between the nominal rail and the clamp onset, ensuring the diode stays off during normal 6.4 V operation and only conducts when the surge exceeds the standoff threshold.

Through-hole axial package and environment

DO-201AA (DO-27) axial leaded package, through-hole mount — the leads handle the high peak current without the trace-lift risk of a surface-mount package under a 1500 W pulse.

Obsolete — sourcing through independent distribution

RoHS and REACH compliance documentation is provided with the shipment.
