For a 12 V or 15 V DC bus in industrial or telecom gear, this part absorbs the surge without letting the downstream regulator see more than 25.2 V. ## Obsolete — sourcing through surplus channels Microsemi has marked the 1.5KE18AE3/TR13 as obsolete. The DO-201AA (DO-27) axial-lead package is a standard footprint; a replacement TVS with the same package and similar clamping voltage can be sourced, but a pin-compatible cross-reference from Microsemi is not published. A board-spin evaluation is advisable if the original part is no longer obtainable. ## Package and temperature range Operating junction temperature spans -65 °C to +150 °C, covering the full industrial and military temperature envelope.","metaTitle":"Microsemi 1.5KE18AE3/TR13 Zener TVS, 1500W, DO-201AA","metaDescription":"Microsemi 1.5KE18AE3/TR13 Zener TVS diode, 1500W peak pulse, 25.2V clamping, DO-201AA axial.
