AEC-Q101 TVS for automotive transient protection
The 1.5SMC160AHE3/9AT: The 136V reverse standoff voltage means this part sits across a 120V or 130V nominal rail without conducting in normal operation, only clamping when the line exceeds the 152V minimum breakdown threshold. That margin suits 12V/24V automotive systems with high-voltage bus architectures or DC-DC converter outputs in hybrid/EV powertrains.
Package and reflow compatibility
Housed in the DO-214AB (SMC) package with supplier device package designation DO-214AB (SMCJ), this TVS uses the standard JEDEC footprint shared across the 1.5SMC family. The surface-mount body mates with a solder pad pattern common to SMC diodes, so no layout change is needed if swapping between 1.5SMC voltage grades. The -65°C to +150°C junction temperature range covers under-hood ambient plus self-heating during a pulse event. For reflow, the standard SMC profile applies — the part's moisture sensitivity level is not explicitly stated in the listing, so pre-bake at 125°C for 24 hours if the reel has been opened longer than the floor life typical for this package class.
Sourcing and compliance posture
As an AEC-Q101 qualified device, it ships with the automotive-grade PPAP documentation and traceability expected for Tier-1 production. The 'HE3' suffix indicates Vishay's automotive-grade lead-free plating.
