Description
The STR-S6301 is an original Sanken hybrid integrated circuit engineered specifically for line-operated switching regulators and power supply architectures. This power-management module seamlessly incorporates a high-voltage 3-layer silicon power switching transistor alongside dedicated drive and control circuitry, offering robust over-current protection utilizing a photocoupler isolation element.
Key Features:
- Manufacturer: Sanken Electric Co., Ltd.
- Package Type: ZIP-9 / SIP-9 (9-pin Single/Zig-Zag In-line Power Package) with an integrated metal cooling fin for optimized heat dissipation.
- Internal Componentry: Features a high-voltage silicon power transistor rated for a 500V collector-emitter voltage limit.
- Protection & Isolation: Direct-control switching regulation featuring localized drive circuits and built-in over-current protection (designed for primary/secondary isolation via photo-couplers).
- Condition: Brand New / New Old Stock (NOS)
A crucial vintage semiconductor choice for electronics repair technicians and arcade preservationists looking to repair old CRT TV power boards, legacy monitors, and classic switch-mode power supplies (SMPS).
