It clamps a 6.1A (10/1000µs) surge to 244V maximum, with a reverse standoff of 138V and breakdown voltage range of 153V minimum. ## Obsolete — sourcing through independent channels Availability is lot-specific; quantities and pricing are confirmed at RFQ time. No pin-compatible direct replacement is listed — a board spin or alternate TVS selection may be required for new designs. ## Where the ratings matter for fit The 244V clamping voltage at 6.1A sets the maximum transient voltage the downstream circuitry sees — any load rated below 244V peak needs additional protection or margin. The 138V standoff means the diode does not leak appreciably below that DC bus voltage, so it can sit across a 120V rail without conducting. DO-201AA (DO-27) axial leaded package suits through-hole assembly with a 1.5KE supplier device package footprint. The tape-and-box packaging (73 per ammo pack) is typical for auto-insertion lines.","metaTitle":"1.5KE170HE3/73 Vishay TVS Diode, 1500W, 244V Clamp, DO-201AA","metaDescription":"Vishay 1.5KE170HE3/73 TVS Zener diode, AEC-Q101, 1500W peak pulse, 244V clamp at 6.1A.
