Obsolete 1.5kW Zener TVS — sourcing through independent channels
The 1.5KE27AE3/TR13: It is housed in the DO-201AA (DO-27) axial leaded package, suitable for through-hole mounting on general-purpose circuit protection boards.
Temperature range and package — board-fit considerations
Operating over -65°C to 150°C junction temperature, the 1.5KE27AE3/TR13 covers the full industrial and military temperature envelope — suitable for outdoor enclosures, engine bays, or avionics bays without derating concerns. The DO-201AA axial package measures 9.1 mm body length with 0.96 mm lead diameter — standard for through-hole insertion on 0.3-inch pitch boards; the lead bend radius must be maintained to avoid cracking the glass passivation.
