Description
The STR-S6707 is an original Sanken hybrid integrated circuit designed to meet the high reliability and integration demands of off-line quasi-resonant flyback power converters. This robust device incorporates advanced primary control and proportional drive circuitry alongside a third-generation high-voltage bipolar switching transistor inside a single power package.
Key Features:
- Manufacturer: Sanken Electric Co., Ltd. (Originally distributed via Allegro MicroSystems)
- Package Type: Over-molded SIP-9 / ZIP-9 (9-pin Single/Zig-Zag In-line Power Package) featuring an integrated isolated heat spreader.
- Topology: Quasi-Resonant Flyback (Delivers exceptional efficiency, low-power standby mode, and minimized electromagnetic interference/EMI).
- Absolute Maximum Ratings: Maximum Supply Voltage (VIN) of 15V, Output Voltage (VCEX) of 850V, and a 12A collector peak current rating.
- Built-In Protections: Fully equipped with pulse-by-pulse over-current limiting, latched over-voltage protection (OVP), internal under-voltage lockout (UVLO) with hysteresis, and thermal shutdown (TSD) safety controls.
- Condition: Brand New / New Old Stock (NOS)
Widely utilized by vintage electronics repair benches and arcade preservationists for servicing retro television chassis, legacy CRT monitor power boards, and classic switch-mode power supplies (SMPS) requiring an exact-match semiconductor replacement.
