Product details

AEC-Q101 qualification and deployment in automotive electronics

The 1.5KE33AHA0G: Rated Automotive grade and AEC-Q101 qualified — this diode meets the stress and reliability screening required for under-hood and chassis-mounted ECU modules.

DO-201 axial package and board integration

Supplied in a DO-201AA (DO-27) axial through-hole package — a standard footprint for high-power TVS diodes that handles the 1500W pulse without exceeding the lead-frame thermal capacity. The Tape & Box (TB) packaging is suited for hand-insertion or wave-solder assembly; the axial leads allow the body to be mounted flush to the board or elevated for convective cooling.
