The clamping voltage is 22V max at the rated 68.2A peak pulse current — that's the ceiling the protected circuit sees. For a 12V bus with 20V-tolerant downstream parts, this clamp margin is comfortable; for a 12V bus feeding a 5V regulator, you'd want a lower-voltage TVS upstream. ## Package and polarity for the board It's a bidirectional device — one channel, no polarity marking needed. The junction temperature range is -65°C to 150°C, so it survives cold-soak and hot underhood environments without derating issues. The 1500W rating is at 25°C; derate linearly above that per the datasheet curve. Pricing and stock are confirmed at quote time.
