Automotive-grade transient suppression for 214V rails
The 1.5KE250CA-AT/B: It clamps transients at 344V maximum with a 214V reverse standoff voltage, protecting downstream electronics on 200V-class DC buses or automotive load-dump events.
What the key ratings mean for your BOM
The 214V reverse standoff voltage defines the maximum continuous DC voltage the diode can block without conducting — it sits across a 200V nominal rail and stays invisible until a transient exceeds 237V minimum breakdown. The bidirectional design means it clamps equally for positive and negative transients — useful on AC-coupled or bipolar signal lines where polarity is unpredictable.
