Product details

1.5kW bidirectional TransZorb for automotive bus clamping

The 1.5KE39CAHE3_A/C: With a 33.3 V reverse standoff voltage and 37.1 V minimum breakdown, it protects 24 V nominal automotive buses from load-dump and inductive kickback transients where the normal operating rail stays under 33 V. The single bidirectional channel handles positive and negative polarity surges in one package — no need to orient the diode on the PCB.

This part carries AEC-Q101 automotive qualification, meaning it has passed the stress, reliability, and PPAP requirements for under-hood and body electronics deployment.
