The \"AQ\" suffix on the Diotec order code indicates automotive quality grade — listed alongside the automotive applications field, this signals the part is intended for harness-level transient suppression in vehicle electrical systems. ## Package and sourcing posture DO-214AB (SMC) surface-mount package — the large cathode pad area under the SMC body provides thermal relief during a clamping event; PCB layout should spread that pad to the copper plane.","metaTitle":"Diotec 1.5SMCJ15CA-AQ TVS Diode, 15V, 1500W, DO-214AB","metaDescription":"Diotec 1.5SMCJ15CA-AQ bidirectional TVS Zener, 15V standoff, 24.4V clamping, 1500W peak pulse at 10/1000 µs.
