AEC-Q101 qualification and the 1500 W pulse rating
The SMCJ9.0CAQ-13-F: The single bidirectional channel clamps transients of either polarity, so a single device covers both positive and negative surges on a signal or power rail. The -55°C to 150°C junction temperature range covers the full under-hood and cabin thermal profile, so it fits ECU, BMS, and sensor module designs that see 125°C ambient with margin.
Housed in the DO-214AB (SMC) package, the device is surface-mount with a large copper tab on the cathode side. The exposed pad carries the heat into the PCB copper plane — the 1500 W pulse rating assumes a low-thermal-resistance board layout with adequate pad area and thermal vias under the tab. The tape-and-reel packaging suits automated pick-and-place assembly.
Active production and sourcing posture
The product status is Active, meaning the manufacturer continues to produce the SMCJ9.0CAQ-13-F and accepts new orders.
