When a transient exceeds the 162V minimum breakdown voltage, the diode clamps the surge to 234V maximum, shunting up to 6.4A of peak pulse current away from the protected circuitry. ## Through-hole mounting for board-level transient clamping Housed in the DO-201AA (DO-27) axial-lead package, this TVS diode mounts through-hole on a standard 0.100-inch pitch grid. The leaded format allows manual or wave-solder assembly and provides a robust mechanical connection for applications where vibration or thermal cycling is a concern. The device is rated for general-purpose transient suppression and does not include power line protection features — it is intended for secondary-side or signal-line clamping.","metaTitle":"Vishay 1.5KE170CA-E3/54 TVS Diode, 1500W, 145V Standoff","metaDescription":"Vishay 1.5KE170CA-E3/54 TransZorb bidirectional TVS diode. 1500W peak pulse power, 145V standoff, 234V clamp.
