Description
The STR-30134 is an original Sanken thick-film hybrid integrated circuit designed specifically as a fixed voltage regulator for line-operated color television chassis, monitor power supplies, and vintage electronics chassis. Part of Sanken's classic STR30000 series, this power management device incorporates a high-performance triple-diffused planar Darlington power switching transistor alongside its dedicated reference voltage and drive circuitry inside a single robust module.
Key Features:
- Manufacturer: Sanken Electric Co., Ltd. (Cross-referenced to standard replacement types like ECG1778).
- Package Type: 5-Pin Single In-line Power Package (SIP-5 / TO-3P modification) with an integrated metal cooling fin and a single mounting hole for heat sinking.
