With a breakdown voltage of 162V minimum and a clamping voltage of 234V at a peak pulse current of 6.4A (10/1000µs waveform), it protects downstream semiconductors from voltage spikes in telecom rectifiers, industrial power supplies, and battery-charger outputs. ## Clamping voltage and pulse current — the protection envelope The 234V maximum clamping voltage at 6.4A peak pulse current defines the let-through voltage the protected circuit must survive. For a 145V nominal rail, the 162V minimum breakdown provides margin above the operating voltage to avoid nuisance triggering during normal ripple or turn-on surges. The single unidirectional channel is suited for DC rails where polarity is fixed; for AC or bidirectional lines, two devices or a bidirectional variant would be needed. ## DO-214AB surface-mount footprint and reflow integration Housed in the DO-214AB (SMC) package, the device occupies a standard surface-mount footprint compatible with lead-free reflow profiles. The supplier device package is also designated DO-214AB (SMCJ), ensuring interchangeability with industry-standard SMC footprints for TVS diodes in this power class. The 1500W pulse rating must be derated at elevated temperatures per the manufacturer's power derating curve in the datasheet. ## Active production — sourcing posture for BOM integration The Tape & Reel packaging (TR suffix) is the standard supply form for automated pick-and-place assembly lines.","metaTitle":"Vishay 1.5SMC170A-M3/9AT TVS Diode, 1500W, 145V Standoff","metaDescription":"Vishay 1.5SMC170A-M3/9AT Zener TVS diode, 1500W peak pulse power, 145V reverse standoff, DO-214AB SMC.
