It delivers up to 13 W in a non-isolated flyback topology, with a fixed 60 kHz switching frequency that simplifies transformer design at the cost of some EMI tuning flexibility. The 730 V breakdown rating provides ample margin for universal mains (85–265 VAC) applications, absorbing line transients without external clamping. The 13 W power ceiling suits auxiliary supplies, appliance control boards, and industrial bias rails where a discrete MOSFET-plus-controller solution would consume more board area and BOM line items. Three integrated fault protections — current limiting, over-temperature, and over-voltage — eliminate the need for external sense resistors, thermistors, or OVP comparators. The over-voltage protection monitors the Vcc winding; a fault latches the controller off until the input is cycled, which is the standard behaviour for a self-supplied flyback. In a real 13 W flyback running in a 70°C ambient, the junction will sit well below 125°C with adequate copper on the 8-DIP's heatsink tabs — the 150°C ceiling gives headroom for fault conditions like output short circuits that drive the die temperature up before the thermal protection engages. Supply voltage range is 9 V to 38 V (Vcc/Vdd), with a 14.5 V start-up threshold. The wide Vcc range allows the auxiliary winding to self-supply the IC after start-up across varying output loads, which is typical for a flyback where the Vcc winding voltage tracks the output. The base product number VIPER12 covers multiple package and lead-free variants; the -E suffix denotes the lead-free / RoHS-compliant version in the 8-DIP package.","metaTitle":"STMicroelectronics VIPER12ADIP-E VIPER™ offline switcher","metaDescription":"ST VIPER12ADIP-E offline switching regulator, 13 W non-isolated flyback, 730 V breakdown, 60 kHz, -40 to 150°C, 8-DIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"STMicroelectronics","Series":"VIPER™","Package":"Tube","Topology":"-","Duty Cycle":"-","Mounting Type":"Through Hole","Power (Watts)":"13 W","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"-","Fault Protection":"Current Limiting, Over Temperature, Over Voltage","Output Isolation":"Non-Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"14.5 V","Base Product Number":"VIPER12","Voltage - Breakdown":"730V","Frequency - Switching":"60kHz","Operating Temperature":"-40°C~150°C(TC)","Supplier Device Package":"8-DIP","Voltage - Supply (Vcc/Vdd)":"9V ~ 38V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/432c6d1734bb4d8458c46b24c8cd47d4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER12ADIP-E/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between VIPER12ADIP-E and VIPER12ADIP?","answer":"The -E suffix on VIPER12ADIP-E indicates the lead-free / RoHS-compliant version. The VIPER12ADIP (without -E) is the earlier tin-lead variant. Both share the same 8-DIP package, 13 W power rating, 730 V breakdown, and 60 kHz switching frequency. The -E version is the current production standard; the non-E version may still be found in legacy BOMs but is not recommended for new designs due to RoHS exemption expiry."},{"question":"Does VIPER12ADIP-E have overvoltage protection?","answer":"Yes. The fault protection block includes over-voltage protection in addition to current limiting and over-temperature. The OVP monitors the Vcc supply voltage; if Vcc exceeds the threshold, the controller latches off and the part must be power-cycled to restart."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/VIPER12ADIP-E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/VIPER12ADIP-E when reusing this data.
