AEC-Q101 qualification places this part in the automotive grade tier — the OEM auditor will ask for PPAP documentation from the authorized distribution channel. The -55°C to 150°C junction temperature range covers underhood and cabin environments. ## Voltage clamping triplet and pulse current rating The three voltage thresholds that define the protection corridor: reverse standoff (30V typical) is the DC bus voltage the part blocks without conducting; breakdown (33.3V minimum) is where avalanche starts; clamping (48.4V maximum at 8.3A Ipp) is the peak voltage the downstream circuitry sees during a surge. For shorter pulses (8/20µs waveform common in IEC 61000-4-5), the peak power capability is significantly higher — the 400W rating is the conservative anchor for worst-case line-length surges. The DO-214AC (SMA) package with a glass-passivated junction handles the thermal pulse without secondary breakdown. The copper pad area on the PCB under the cathode tab sets the thermal impedance for repetitive surge events. ## Active production status and sourcing posture Pricing and availability confirmed at RFQ time. The base product number SMAJ30 covers the family; the -F suffix indicates lead-free and RoHS-compliant finish.","metaTitle":"Diodes Inc SMAJ30CAQ-13-F TVS, 30V, 400W, DO-214AC","metaDescription":"AEC-Q101 qualified bidirectional TVS diode, 30V standoff, 400W peak pulse power, DO-214AC (SMA) package.
