Rated for 100 W output with a 620 V breakdown voltage, it targets isolated offline AC-DC converters in industrial and consumer power supplies up to 200 kHz switching frequency. ## Staggered-lead Pentawatt — reflow and placement notes The Pentawatt-5 HV package uses bent and staggered leads — the offset reduces tombstoning risk during reflow compared to a straight in-line power package. Surface-mount mounting type means it sits flat on the board, but the staggered lead pitch requires a custom footprint; verify the pad geometry against the package drawing before the stencil cut. For a BOM line that cannot redesign, the surplus channel is the practical path; for new designs, evaluate current ST VIPER parts with similar power and package characteristics.","metaTitle":"VIPER100-E STMicroelectronics VIPER™ Flyback, 100 W","metaDescription":"VIPER100-E STMicroelectronics VIPER™ flyback switching regulator, 100 W output, 620 V breakdown, up to 200 kHz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"STMicroelectronics","Series":"VIPER™","Package":"Tube","Topology":"Flyback","Duty Cycle":"-","Mounting Type":"Surface Mount","Power (Watts)":"100 W","Package / Case":"Pentawatt-5 HV (Bent and Staggered Leads)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"EN, Frequency Control, Soft Start","Fault Protection":"Current Limiting, Over Temperature","Output Isolation":"Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"11 V","Base Product Number":"VIPER100","Voltage - Breakdown":"620V","Frequency - Switching":"Up to 200kHz","Operating Temperature":"-","Supplier Device Package":"5-PENTAWATT","Voltage - Supply (Vcc/Vdd)":"8V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cae7141e09cc3caa626c24c122dabd65.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER100-E/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy VIPER100-E?","answer":"The VIPER100-E is obsolete and sourced through independent distribution."},{"question":"What is the difference between VIPER100 and VIPER100-E?","answer":"The evidence does not provide a direct comparison between VIPER100 and VIPER100-E.
