At 5.8 A peak pulse current the clamping voltage sits at 259 V maximum, which is the let-through ceiling the downstream load never exceeds regardless of surge severity up to that level. ## Standoff, breakdown, and clamping — the TVS voltage stack 160 V reverse standoff is the working voltage — above it the diode begins to conduct. The minimum breakdown threshold is 178 V, so the diode stays fully off at 160 V with margin. Once a transients exceeds that threshold, the device clamps at or below 259 V and holds the protected rail within that ceiling through the surge event. This is a unidirectional polarity device — the cathode pins to the positive rail, the anode to ground. It does not protect AC lines or bidirectional rails; a reversed polarity placement leaves the protected circuit exposed. Confirm the polarity orientation against the board silkscreen before assembly and rework. ## 150 °C junction temperature — thermal margin for transient absorption The maximum junction temperature of 150 °C gives thermal headroom for back-to-back transients where the duty cycle compresses the recovery interval. The diode's thermal impedance to ambient determines whether successive pulses fully cool between events — for a high-energy surge train, verify the thermal design against the diode's transient thermal impedance curve in the full datasheet. ## SMC/DO-214AB surface-mount footprint — layout and rework note The SMC (DO-214AB) package mounts surface-mount to a standard 4-pin footprint. The cathodic center-pad lands on the protected rail; the anode tabs ground to the plane. Board pad geometry affects solder-joint reliability under thermal cycling — confirm the land pattern matches the Diotec recommended footprint for this package before layout lock. Strip packaging indicates the part ships non-reeled — confirm the assembly process handles loose pieces or requires reeled product for pick-and-place volume. The 1.5 kW peak pulse rating in this package is a mid-range SMC device — the anode and cathode tab dimensions set the primary heat-spreading path to the PCB copper.","metaTitle":"Diotec 1.5SMCJ160A TVS Diode, 1.5kW 160V","metaDescription":"Diotec 1.5SMCJ160A unidirectional TVS diode, 1500W peak pulse, 160V standoff, SMC/DO-214AB.
