When a transient exceeds 162V, the Zener avalanche breaks down and clamps the voltage to 234V maximum, shunting the surge energy through the 1500W-rated die. ## Package and rework considerations Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE170A is straightforward to hand-solder or wave-solder. The axial body has a single cathode band for polarity marking — no pin 1 ambiguity. The large lead diameter and body size handle the thermal pulse of a 1500W surge without cracking the epoxy encapsulation. The wide junction temperature margin means the TVS can absorb repeated surges without derating the peak pulse power at elevated ambient temperatures. ## Active production and sourcing posture Sourced to order against your BOM quantity through independent distribution.","metaTitle":"Littelfuse 1.5KE170A TVS Diode, 1500W, 145V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE170A Zener TVS diode, 1500W peak pulse power, 145V reverse standoff, 234V clamping.
