The 145V reverse standoff voltage (working voltage) means the TVS draws negligible leakage below that level — the protected rail runs at 145V or less without the diode conducting. The 162V minimum breakdown ensures the device starts clamping before the rail exceeds its absolute maximum rating, while the 234V maximum clamp limits the voltage spike the downstream circuitry sees during a surge. At 6.4A peak pulse current (10/1000µs), the clamp voltage hits 234V. For a 1500W pulse, the dynamic resistance is low enough that the clamp voltage stays within the 234V ceiling across the full pulse current range — no secondary breakdown worry in a standard surge event. ## Package and board-fit for rework The DO-214AB (SMC) body is about 7.1mm long by 6.2mm wide — large enough to hand-solder or hot-air rework without a stencil. The anode and cathode bands are clearly marked on the body; for a bidirectional part the marking is symmetric, so orientation is non-critical. The copper pad area under the package should match the recommended land pattern in the Vishay application note to keep the thermal impedance low for repetitive pulse trains. Tape-and-reel packaging suits automated pick-and-place. The MSL rating is typically Level 1 for this glass-passivated construction — no bake-out required before reflow, which simplifies the assembly line setup.","metaTitle":"1.5SMC170CA-M3/57T Vishay TVS, 1500W Bidirectional, DO-214AB","metaDescription":"Vishay 1.5SMC170CA-M3/57T bidirectional Zener TVS, 1500W peak pulse, 145V standoff, 234V clamp.
