1.5kW automotive TVS in a DO-201 axial package
The 1.5KE250AHB0G: It clamps transients at 344V maximum, with a 214V reverse standoff voltage that keeps the protected rail below the clamping threshold during normal operation. Rated for a peak pulse current of 4.5A under the 10/1000µs condition, this part handles repetitive surge events in 12V and 24V automotive systems where the nominal bus voltage sits well below the 214V standoff — typical for load-dump and inductive kickback protection on ECU power inputs.
AEC-Q101 qualification and temperature range
The 175°C TJ max provides margin above the 150°C typical for automotive-grade passives. The series designation 'Automotive, AEC-Q101, 1.5KE' confirms it meets the stress test and reliability requirements for automotive electronic systems, including temperature cycling, ESD, and humidity bias.
