Product details

1500W bidirectional TransZorb — what the ratings mean

The 1.5KE220CAHE3/51: Peak pulse current is 4.6 A at the same 10/1000 µs waveform — the clamping voltage times this current stays within the 1500 W power rating.

Automotive qualification and operating range

AEC-Q101 qualified — the part is screened for automotive-grade reliability, including temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive stress test profile. Junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal environments where the ambient can exceed 125°C. Single bidirectional channel in a DO-201AA (DO-27) axial-lead through-hole package — the body handles the 1500 W pulse without external heatsinking for single-event surges.

Frequently asked questions

Where can I buy 1.5KE220CAHE3/51 and check availability?

This part is available through independent distribution channels.

What is the closest pin-compatible alternative to 1.5KE220CAHE3/51?

For a functional replacement, look at the active 1.5KE series parts in the same DO-201AA package with matching 185 V standoff and bidirectional polarity — confirm the clamping voltage and peak pulse power match your circuit requirements before substituting.
