Product details

1.5kW pulse rating in an axial DO-201 package

The 1.5KE39AHB0G: This is a through-hole part in a DO-201AA (DO-27) axial-lead package, which makes it straightforward to hand-solder into a prototype or a repair board — no hot-air station needed, just a soldering iron and a clean pair of cutters for the leads.

Because it is a single unidirectional channel, it protects one rail per device — typical for clamping a 24V automotive bus or a 28V avionics supply where the normal operating voltage sits below the 33.3V standoff.

Frequently asked questions

Is the 1.5KE39AHB0G automotive qualified?

Yes, it carries AEC-Q101 qualification, making it suitable for automotive-grade applications that require the stress testing and reliability screening defined by that standard.

What package does the 1.5KE39AHB0G come in?

It is a through-hole axial-lead device in a DO-201AA (DO-27) package, supplied in bulk. The supplier device package is designated DO-201.
