At that point it clamps the surge to 19.9V maximum, shunting up to 30.2A of peak pulse current in the 10/1000µs waveform. For a 12V bus in a 85°C enclosure, budget roughly 70% of the 600W rating. ## Package and board integration The SMB package has a larger copper pad area than the smaller SMA sibling, which helps spread heat from repetitive pulse events. The supplier device package is SMB. Power line protection is not provided — this is a signal or low-voltage rail protector, not a mains surge suppressor.","metaTitle":"SMBJ12A-13 Diodes Inc TVS Diode, 12V, 600W, DO-214AA","metaDescription":"SMBJ12A-13 Zener TVS diode, 12V reverse standoff, 600W peak pulse, DO-214AA SMB package.
