Description
The Philips 006125860K01 is an original equipment manufacturer (OEM) replacement power module, physically containing the authentic Sanken STR-30123 thick-film hybrid integrated circuit. Primarily utilized as a primary-side fixed voltage regulator in line-operated television chassis and retro gaming 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 factory replacement part under the Philips / Magnavox service network).
- Factory Part Number: 006125860K01 (Cross-referenced directly to standard Sanken STR-30123 / STR30123).
- Package Type: 5-Pin Single In-line Power Package (SIP-5 / ZIP-5 / TO-3P modification) featuring an integrated 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 123V (±0.8V) under a 200V maximum peak input voltage ceiling, rated for up to 1.0A of continuous output current and 27W of maximum power dissipation.
- Common Applications: Extensively relied upon for repairing primary power supplies in specialized color TV chassis, vintage video displays, and arcade monitor assemblies (such as the Wells Gardner K7000 series at location IC4 or Zenith K7000A boards replacing part 223-18-01).
- Condition: Brand New / New Old Stock (NOS)
An increasingly scarce, obsolete component relied upon heavily by specialized electronic bench technicians, retro arcade preservationists, and legacy CRT TV restoration hobbyists who require an exact factory cross-match to safely rebuild primary power supply grids back to original operation limits.
