Product details

Automotive-grade 1500 W transient clamp

The 1.5KE24CAH: It clamps transients at 33.2 V maximum while standing off 20.5 V continuously, with a breakdown voltage window of 22.8 V minimum.

Clamping voltage and pulse current for 24 V rails

With a 20.5 V reverse standoff and 33.2 V clamp, this part protects 24 V nominal buses (12 V or 24 V automotive systems) where the steady-state rail stays below 20.5 V and the clamp triggers before the downstream IC's abs-max rating is exceeded.

Through-hole DO-201 for high-reliability assembly

The DO-201AA (DO-27) axial leaded package is a standard through-hole form factor for TVS diodes, offering robust solder joint strength and easy manual or wave-solder assembly. The supplier device package is DO-201. Packaged in Tape & Reel (TR), it is compatible with automated insertion equipment for volume production.

Frequently asked questions

What automotive qualification does 1.5KE24CAH carry?
