Product details

Active production and automotive-grade TVS protection

The 1.5KE15AHE3_A/C: The 70.8A peak pulse current rating gives headroom for high-energy surges common in automotive 12V/24V systems.

Clamping voltage and breakdown margin

Breakdown voltage is specified at 14.3V minimum, ensuring the device starts conducting before the protected rail exceeds the safe operating area of downstream electronics. The 21.2V maximum clamping voltage limits the spike seen by the load. The DO-201AA axial package (DO-27 variant) is a through-hole footprint that handles the thermal dissipation of repeated 1500W pulses.

Frequently asked questions

Is the 1.5KE15AHE3_A/C AEC-Q101 qualified?
