Product details

What 5kW peak pulse means for protection

The 5-0SMDJ22AH: The 24.4 V minimum breakdown voltage sits above the 22 V reverse standoff, so the TVS stays invisible in normal operation and activates only on a genuine overvoltage — a key distinction for ISO 7637-2 automotive conducted transient compliance testing.

Automotive grade — what AEC-Q101 qualification means

Primary applications are automotive and telecom, where load-dump and ESD transients are the design drivers — the unidirectional single-channel topology handles the typical reverse-polarity surge direction seen in 12 V and 24 V vehicle rails.

DO-214AB SMC footprint and thermal layout

Tape-and-reel and cut-tape packaging options suit both high-volume SMT placement and low-run rework kitting — the component ships on a 330 mm reel in standard orientation for automated optical inspection alignment.

Frequently asked questions

What is 5-0SMDJ22AH used for?

It is a unidirectional TVS Zener for automotive and telecom transient protection — it clamps reverse-polarity surges on a 22 V rail up to 141 A peak without letting the downstream circuitry see more than 35.5 V. The AEC-Q101 qualification makes it suitable for under-hood and exterior zones where temperature extremes and transient stress are the design drivers.
