Product details

The 1.5KE170AHA0G: The 1500 W (1.5 kW) peak pulse power rating means it can absorb substantial surge energy — enough for automotive load-dump and ISO 7637-2 pulses on 12 V and 24 V systems, or for industrial 48 V bus protection. The through-hole DO-201AA (DO-27 axial) package is a field-service favourite: easy to swap with a soldering iron, no hot-air station needed, and the polarity band is clearly marked on the body.

Automotive-grade and temperature range

The 1.5KE series is a well-established TVS platform; the A0G suffix indicates the automotive-qualified variant with tape-and-box packaging. No power line protection is built in — this is a unidirectional transient suppressor for signal and low-voltage DC power rails, not for AC mains.

Frequently asked questions

Where can I buy the 1.5KE170AHA0G and what is the lead time?

The 1.5KE170AHA0G is an active part from Taiwan Semiconductor and can be sourced through independent distribution.

What package does the 1.5KE170AHA0G come in?

It comes in a through-hole DO-201AA (DO-27 axial) package. The supplier device package is DO-201. This axial leaded package is straightforward to replace in the field with basic soldering tools.
