The single bidirectional channel means it clamps both polarities symmetrically — no orientation concern during through-hole insertion into a DO-201AA axial footprint. ## 1500W pulse and 100A Ipp — what the ratings mean for line protection The 1500W peak pulse rating at 10/1000µs defines the energy the device absorbs in a single transient event before the junction temperature exceeds the 175°C absolute maximum. For a 24V nominal bus, the 8.1V standoff is too low — this part is sized for low-voltage DC rails where the steady-state voltage stays under 8.1V. 100A peak pulse current at the clamping voltage of 15V means the TVS can handle a direct lightning-induced surge on a signal line without failing short, provided the source impedance limits the total energy. The through-hole axial package handles the thermal pulse better than an equivalent SMD footprint because the lead frame sinks heat into the PCB hole plating. ## Obsolete — sourcing and lifecycle posture Vishay has marked the 1.5KE10C-/73 as Obsolete. No official successor order code is recorded, and the TransZorb family has migrated to newer package variants and higher surge ratings over successive generations. The Tape & Box (TB) packaging indicates bulk axial handling rather than reel, common for through-hole TVS in maintenance or small-lot production.","metaTitle":"1.5KE10C-E3/73 Vishay TransZorb TVS, 1500W Bidirectional","metaDescription":"Vishay 1.5KE10C-E3/73 TransZorb Zener TVS, 1500W peak pulse, 8.1V standoff, 100A Ipp. Obsolete — sourced to order against RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Box (TB)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE10","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"9V","Voltage - Clamping (Max) @ Ipp":"15V","Voltage - Reverse Standoff (Typ)":"8.1V","Current - Peak Pulse (10/1000µs)":"100A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the peak pulse power rating of the 1.5KE10C-/73?","answer":"1500W (1.5kW) at a 10/1000µs waveform.
