That 38A figure is the current the diode shunts at the 10/1000µs test pulse; real-world transients shorter than 1ms allow higher peak current before the junction temperature limit is reached. ## Through-hole DO-201 package and board integration The DO-201AA (DO-27) axial-lead package is a through-hole form factor — the leads insert into plated through-holes on the PCB and are wave-soldered. The 0.042-inch (1.07mm) lead diameter handles the 38A pulse current without fusing, but the PCB trace width feeding the cathode and anode pads must be sized for the peak current; a 2oz copper trace at least 2mm wide per leg keeps the IR drop below 0.1V during the pulse. The axial body sits above the board — no thermal pad underneath, so the junction-to-ambient thermal resistance is dominated by the lead length and the copper pad area on the board.","metaTitle":"1.5KE30CAHB0G TVS Diode, 1.5kW, 25.6V, DO-201, AEC-Q101","metaDescription":"1.5KE30CAHB0G bidirectional TVS diode, 1500W peak pulse, 25.6V standoff, AEC-Q101 qualified.
