The 9.4V reverse standoff voltage (VRWM) is the DC rail voltage the part sits across without conducting — the protected circuit runs at 9.4V or below, and the diode stays off. At 10.5V minimum breakdown (VBR), the device starts to avalanche and clamp the transient. That 15.6V is the voltage the downstream components must survive during a surge event — a 16V-rated capacitor on the rail has no margin here. The DO-201AA axial package (also known as DO-27) is through-hole — the leads handle the thermal cycling of high-reliability assemblies better than an SMD solder joint in extreme environments. ## Where a TransZorb TVS fits in the protection scheme General-purpose transient suppression for DC power rails, signal lines, and low-voltage bus protection in industrial controls, telecom equipment, and automotive electronics.","metaTitle":"Vishay 1.5KE11CA-E3/54 TransZorb TVS, 1500W, 9.4V Standoff","metaDescription":"Active Vishay 1.5KE11CA-E3/54 bidirectional TVS diode, 1500W peak pulse, 9.4V standoff, DO-201AA axial.
