The 1500W peak pulse rating assumes the device starts within this range; derate above 25°C per the standard power-temperature curve for axial-lead TVS diodes. With a single unidirectional channel, this part protects one rail per device. If your board needs bidirectional clamping or multiple lines, you stack two back-to-back or use a different series. The 112A peak pulse current at the 10/1000µs test waveform gives a practical surge-handling figure for estimating let-through energy into the downstream circuit. ## Obsolete — sourcing through independent channels Panjit has marked the 1.5KE9.1A_R2_00001 as obsolete. No official successor order code is recorded in the lifecycle data. This means the part is no longer manufactured and is not available through standard authorized distribution channels.","metaTitle":"Panjit 1.5KE9.1A_R2_00001 TVS Diode, 1.5kW, DO-201AE","metaDescription":"Panjit 1.5KE9.1A_R2_00001 Zener TVS diode, 1500W peak pulse, 7.78V standoff, DO-201AE axial.
