What the AEC-Q101 grade means for the BOM
The SMCJ6.0AQ-13-F is a Zener-type TVS diode from Diodes Incorporated, part of the Automotive, AEC-Q101 series. At the clamping voltage of 10.3V max, the device conducts 145.6A peak pulse current — enough to shunt a load-dump transient or an ISO 7637-2 pulse 5a without the downstream rail exceeding the 10.3V clamp. The 6V reverse standoff voltage matches 5V or 6V nominal rails; the 6.67V minimum breakdown ensures the TVS triggers before the protected rail exceeds its absolute maximum rating.
Housed in the DO-214AB (SMC) package, the SMCJ6.0AQ-13-F is a surface-mount device with a standard footprint shared across the 1500W TVS family. The SMC package provides the copper pad area needed to dissipate the 1500W pulse without exceeding the 150°C junction limit. The unidirectional configuration (1 channel) means the cathode band marks the anode side — orientation matters for the clamping polarity.
