TVS diode for 130V automotive rails
The SMBJ130AQ-13-F: AEC-Q101 qualification certifies it for automotive stress levels: -55°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles. The 144V minimum breakdown voltage and 209V maximum clamping voltage at 2.9A peak pulse current define the protection window — the clamped voltage stays below the downstream silicon's absolute maximum rating.
Package and board-fit for DO-214AA
Supplied in the DO-214AA (SMB) package, surface-mount with the cathode band marking the unidirectional orientation. The SMB footprint is a standard JEDEC outline — the same land pattern serves the entire SMBJ family, so a single PCB layout covers multiple voltage variants. Bulk packaging suits prototype and low-volume builds; reel quantities are also available through the supply chain.
Active production and sourcing posture
No pin-compatible second-source is registered, but the SMBJ family's standardized footprint means a parametric match from another AEC-Q101 TVS supplier is a straightforward cross-reference exercise.
