VIPER12ADIP-E
STMicroelectronicsVIPER12ADIP-E is an STMicroelectronics VIPer-family offline switcher in DIP-8, tube packing — a fixed-frequency 60 kHz PWM controller with an integrated 730 V-class high-voltage MOSFET for auxiliary and standby supplies. It is the lower-power sibling of the VIPER22ADIP-E on this site: ST's datasheet states typical power capability in the DIP-8 package of 13 W on a European 195–265 Vac input and 8 W on a wide-range 85–265 Vac input, and those wattages hold only under the datasheet's stated circuit and input conditions — quote them with the conditions or not at all. The controller supply range is 9 to 38 V. ST's official estore record for this exact code, read in October 2026, lists it as Active — the maker's own status evidence for the orderable code, stated as of that reading rather than as a live-stock claim. Selection advice: choose between the VIPER12A and VIPER22A codes on the datasheet power table for your input range, not on the headline — at wide-range input the smaller part's ceiling arrives quickly. Parameters verified against the ST datasheet and the official ST estore record.
