1500 W peak pulse in a DO-201AA axial package
The 1.5KE8.2AHR0G: It clamps a 7.02 V reverse standoff voltage to 12.1 V maximum at a peak pulse current of 130 A. Built for automotive environments, this part carries AEC-Q101 qualification, meaning it has passed the stress and reliability screens required for under-hood and chassis-mounted electronics.
Through-hole package and rework considerations
The DO-201AA (DO-27) axial-lead package is a through-hole form factor. The leads are stout enough to handle the 130 A surge without fusing, and the body is large enough to dissipate the pulse energy without cracking the epoxy. For a rework tech: the leads are easily dressed and soldered into plated through-holes; the part survives multiple soldering cycles if the board needs a swap. Pin 1 is the cathode band — the band is molded into the body and visible after potting. Because it is a single-channel unidirectional suppressor, orientation matters: the cathode goes toward the protected rail, anode to ground. The 1500 W rating is derated above 25°C per the datasheet curve; at 175°C junction the peak pulse power drops to roughly 25% of the 25°C value.
Active lifecycle and sourcing posture
For a BOM cost engineer: this part is single-sourced from Taiwan Semiconductor Corporation. The AEC-Q101 grade limits alternative sources to other automotive-qualified TVS diodes in the same package and voltage class. If a second source is needed, a parametric search for 1500 W, 7.02 V standoff, DO-201AA, AEC-Q101 is the starting point — no pin-compatible drop-in is guaranteed without verifying the clamping curve.
