The 1.5KE43AH: It protects a single 36.8 V nominal rail from transients up to 59.3 V clamping voltage at a peak pulse current of 26 A (10/1000 µs waveform).
The 36.8 V reverse standoff voltage means it stays transparent on a nominal 36 V supply bus, only conducting when the transient exceeds the 40.9 V minimum breakdown threshold.
The 1.5KE43AH is available to order through independent distribution.
The 1.5KE43AH is a Zener-type TVS diode with an automotive grade rating. It is qualified to AEC-Q101, making it suitable for use in vehicle electrical systems where transient protection on a 36.8 V rail is required.
