Bidirectional single-channel configuration — one device protects both polarities, simplifying PCB layout for AC-coupled or bipolar signal lines. ## Package and rework — DO-201AA axial lead Through-hole DO-201AA (DO-27) axial package, supplier device package CASE-1. The axial leads are robust for hand-soldering or wave-solder; the body is large enough to dissipate the pulse energy without lifting pads, but the lead bend radius matters — sharp bends near the glass seal can crack the body. Keep the bend at least 2 mm from the case. Operating temperature range -65°C to 150°C junction — suitable for outdoor or industrial enclosures where the ambient sees wide swings.","metaTitle":"Microsemi 1.5KE43CAE3/TR13 TVS Diode, 1.5kW, 36.8V Standoff","metaDescription":"Obsolete Microsemi 1.5KE43CAE3/TR13 bidirectional TVS, 1500W peak pulse, 36.8V standoff, DO-201AA.
