Its 111 V reverse standoff voltage lets it sit across a 100 V DC rail without conducting leakage, while the 124 V minimum breakdown ensures the avalanche triggers before the rail sees damaging overvoltage. At the 8.4 A peak pulse current the clamp voltage is 179 V maximum — this is the voltage the protected circuit must survive. The unidirectional configuration (single channel) clamps only one polarity; for AC or bidirectional lines you need the bidirectional variant of the same family. ## Board-fit and thermal envelope Housed in the DO-201AA (DO-27) axial leaded package, the part mounts through hole — the leads are formed for insertion into 1.0 mm diameter plated-through holes on a standard PCB or turret terminal. The junction temperature range spans -55°C to +175°C, covering military and industrial ambient extremes without derating the pulse power at the high end. The 1500 W rating is a peak value at 25°C; above 25°C the power must be derated linearly per the TransZorb datasheet curve. For sustained repetitive pulses, calculate the average power dissipation and compare against the thermal impedance of the lead-to-board solder joint. ## Sourcing and compliance posture Vishay General Semiconductor lists the part for general-purpose applications. No specific automotive, military, or space-grade qualification is stated in the record; the -55°C to +175°C temperature range suggests suitability for industrial and some defense environments, but the buyer should verify the required screening level (e.g., JAN, DESC) separately.","metaTitle":"1.5KE130A-E3/73 Vishay TransZorb TVS, 1500W, 179V Clamp","metaDescription":"Active Vishay 1.5KE130A-E3/73 unidirectional TVS, 1500W peak pulse, 179V clamp @ 8.4A, DO-201AA axial.
