Product details

Clamping window and thermal range for underhood duty

The 1.5KE51CAHE3_A/D: Breakdown voltage is guaranteed at 48.5V minimum, clamping the line at 70.1V maximum when conducting 21.4A peak pulse current. As a single bidirectional channel, the device protects against both positive and negative transients — no polarity orientation needed during assembly.

Sourcing and compliance for BOM placement

AEC-Q101 qualification includes PPAP documentation and device-level reliability testing per automotive-grade requirements. The TransZorb® series is a Vishay trademark for high-energy transient suppressors used in 12V and 24V vehicle power buses.
