Description
The Philips 483520947056 (also cataloged under factory part number 4835 209 47056) is an original equipment manufacturer (OEM) replacement power module, physically containing the authentic Sanken STR-30130 thick-film hybrid integrated circuit. Primarily utilized as a primary-side fixed voltage regulator in line-operated television chassis and CRT monitors, this high-performance component integrates a triple-diffused planar Darlington power switching transistor alongside its internal reference voltage and error feedback control circuitry within a single robust block.
Key Features:
- Manufacturer: Sanken Electric Co., Ltd. (Sourced and cataloged as an OEM replacement part by Philips / Magnavox / Sylvania).
- Factory Part Numbers: Philips 483520947056 / 4835 209 47056 (Cross-referenced to standard Sanken STR-30130 / STR30130).
- Package Type: 5-Pin Single In-line Power Package (SIP-5 / ZIP-5 / TO-3P modification) featuring a molded metallic thermal tab with a single pre-drilled mounting hole for direct heat sink attachment.
- Electrical Specifications: Delivers a highly stable, fixed output target of 130V (±0.5V) under a 200V maximum peak input voltage ceiling, rated for up to 1.0A of continuous output current.
- Common Board Location: Frequently designated at critical primary power regulation paths (such as board location IC4 on Wells Gardner K7000 series and related Philips-serviced arcade or television chassis).
- Condition: Brand New / New Old Stock (NOS)
This increasingly scarce component is heavily relied upon by specialized electronic bench technicians, retro arcade preservationists, and legacy CRT TV restoration hobbyists who require an exact-match original Sanken hybrid pack to safely rebuild primary power grids back to factory specification limits.
