Description
The STK73410II (also written as STK73410-II) is an original Sanyo thick-film hybrid integrated circuit (IC) explicitly engineered as a self-oscillation type, off-line switching voltage regulator module. It is a highly trusted, legacy component widely deployed in the power management stages of vintage color televisions (CTV) and video tape recorders (VTR).
Key Features & Specifications:
- Function: Self-Oscillation Type Off-Line Switching Voltage Regulator
- Maximum Output Power: 100W
- AC Input Voltage Range: Supports line voltages up to 280Vrms (specifically optimized for stable 115V to 200V configurations)
- Package Type: 9-Pin Single In-Line Package (SIP) with an integrated metal substrate backing plate for direct heatsink installation
- Applications: Direct replacement part for power supplies in legacy analog CRT televisions, studio video equipment, and vintage VTR architectures.
- Manufacturer: Sanyo Electric Co., Ltd. (Sanyo Semiconductor Division)
An authentic, New-Old-Stock (NOS) structural semiconductor module. Essential for component-level diagnostics, workbench repairs, and preservation of classic retro-gaming monitors and vintage video production gear.
