VIPER22ADIP-E

VIPER22ADIP-E is an STMicroelectronics VIPer-family offline switcher in DIP-8 — a fixed-frequency 60 kHz PWM controller with an integrated high-voltage MOSFET for auxiliary supplies, standby rails and low-power adapters. The integrated switch is the selection point: drain-source breakdown is 730 V minimum, a peak current limitation (IDlim) of 0.56 A minimum, 0.7 A typical and 0.84 A maximum at VFB = 0 V (datasheet Table 7, at TJ = 25 °C and VDD = 18 V — a protection threshold, not a nominal drain current) and on-resistance 15 Ω typical, 17 Ω maximum at ID = 0.4 A and TJ = 25 °C, with the controller supply range at 9 to 38 V — one 8-pin through-hole part replaces a discrete controller-plus-FET pair in isolated and non-isolated flyback designs. ST's own Quality & Reliability table lists this exact orderable code as Active (DIP-8, Industrial grade, Ecopack1), which settles the status question at the maker rather than through distribution. Selection advice: the DIP-E code is the through-hole DIP-8 — the same VIPER22A family also ships in SMD packages under different codes, and the power capability figures in the datasheet are stated for defined input ranges and circuits, so match both the package code and your input range before layout.
