The DO-201AA axial-lead package (also known as DO-27) is through-hole mounted, suited for point-to-point wiring or PCB insertion where the lead bend absorbs thermal cycling stress. ## Voltage ratings and clamping performance At 7.02V reverse standoff (working voltage), the device draws negligible leakage — it stays off until a transient pushes the line above 7.79V (minimum breakdown). Full clamping happens at 12.1V, where the diode shunts 124A peak pulse current (10/1000 µs) to ground. The 1500W peak pulse rating means the device absorbs a 1 ms surge without failing — derate for longer pulses or higher ambient temperature per the datasheet curve. ## Obsolete — sourcing through independent channels Diodes Incorporated lists the 1.5KE8V2CA-B as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific; pricing and lead time are confirmed at RFQ. The DO-201 package is common across the 1.5KE series, so a functional replacement (different breakdown voltage) may be easier to source than this exact code.","metaTitle":"1.5KE8V2CA-B Diodes Inc Zener TVS, 1500W, Bidirectional","metaDescription":"1.5KE8V2CA-B Diodes Inc Zener TVS diode, 1500W peak pulse, 7.02V standoff, 12.1V clamp, DO-201.
