Product details

5000W peak pulse rating and clamping architecture

The Bourns 5.0SMDJ8.0A-QH is an unidirectional Zener-based TVS diode in the DO-214AB (SMC) package, qualified AEC-Q101 for automotive deployment.

The TVS selection matrix on record

Reverse standoff of 8V sets the continuous working voltage above which the TVS begins to conduct — the clamping voltage of 13.6V at a peak pulse current of 367.7A is the guaranteed maximum the protected line sees during a 10/1000µs surge event. Minimum breakdown of 8.89V marks the onset of conduction at the device's turn-on threshold.
