It clamps a 30 V nominal line at 48.4 V maximum when hit with a 31 A, 10/1000 µs surge waveform. ## Clamp voltage and the 30 V rail The 30 V reverse standoff voltage is the maximum DC or peak-AC voltage the protected line can carry without the diode conducting. The breakdown voltage floor is 33.3 V, so a 30 V supply rail has 3.3 V of headroom before the TVS starts to avalanche — enough margin for a regulated 24 V or 28 V bus with ripple. At the 31 A peak pulse current (10/1000 µs waveform), the clamping voltage rises to 48.4 V maximum. That figure sets the voltage stress the downstream ICs must survive during the surge event — a 48.4 V clamp on a 30 V rail means the protected devices need at least a 50 V breakdown rating on their supply pins. Single unidirectional channel — the cathode band goes to the protected rail, the anode to ground. No power-line protection means this is a signal- or DC-bus clamp, not a mains-side suppressor. ## Active lifecycle, automotive qualification The AEC-Q101 qualification is a strong authority signal for automotive-tier procurement: the part has PPAP-level documentation and is accepted in safety-critical supply chains.","metaTitle":"SMCJ30AQ-13-F TVS Diode, 1500W, 30V Standoff, DO-214AB","metaDescription":"Diodes Inc SMCJ30AQ-13-F Zener TVS, 1500W peak pulse, 30V reverse standoff, AEC-Q101 automotive grade, DO-214AB SMC package.
