The ICTE-005: The 5V reverse standoff voltage means it holds off a 5V rail without leakage; breakdown starts at 6V minimum. That clamping margin — 9.4V on a 5V rail — leaves 4.4V of headroom for the protected load, which is tight for a 5V logic supply but workable if the downstream circuitry is rated for at least 10V.
Package and mounting — DO-201AD axial leaded
Through-hole DO-201AD axial package. The axial leads require a hole diameter of about 1.0 mm on the PCB; the body length is roughly 9.1 mm. This is a legacy footprint — confirm the hole pattern matches your existing board layout before committing to a last-time buy.
The wide range suits applications like avionics power buses, downhole instrumentation, or outdoor telecom line cards.
