1500W Zener TVS diode for 145V rail protection
The 1.5KE170A: The 145V reverse standoff voltage means this part sits across a DC bus or signal line rated up to 145V without conducting appreciable leakage current. 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.
