AEC-Q101 qualified 1500W bidirectional TVS for automotive and telecom transient protection
The 1.5SMC120CAHM3_A/H: This qualification means the part is suitable for underhood and chassis-mounted electronic modules where the OEM auditor will require traceable test data. The 114V minimum breakdown voltage defines the threshold at which the device begins conducting, and the 9.1A peak pulse current drives the clamping action. This combination covers 12V and 24V automotive system surges per ISO 7637-2 and load-dump events. Operating junction temperature spans -65°C to 150°C, matching the full automotive underhood envelope. The DO-214AB (SMC) surface-mount package uses a standard reflow profile; the copper pad area under the cathode tab sets the thermal resistance for continuous power dissipation.
Active production with PPAP-ready documentation for BOM compliance
As an AEC-Q101 qualified device, Vishay provides full PPAP documentation, RoHS/REACH compliance data, and lot traceability. The base product number 1.5SMC120 covers the unqualified industrial variant; the HM3 suffix specifically denotes the automotive-grade screening and qualification.
