Overview
The onsemi 4N273S is a single-channel photovoltaic output optoisolator designed for surface-mount applications. It features a 6-SMD Gull Wing package and provides electrical isolation with an insulation voltage of 5300 Vrms. The device utilizes a DC input type and offers a transistor output with base configuration. Key specifications include a maximum collector-emitter voltage of 30V and a forward voltage of 1.18V. This component is currently listed as obsolete by the manufacturer.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using photovoltaic technology.
Applications
- Signal isolation in electronic circuits
- Interface applications requiring galvanic separation
Procurement Notes
Verify part status carefully as the 4N273S is officially classified as obsolete by onsemi. Availability may be limited to existing stock or third-party distributors rather than direct manufacturing supply. Confirm authenticity and condition when sourcing from non-primary channels due to end-of-life status.
Selection Notes
Consider alternative active components if long-term supply stability is required. Evaluate compatibility with surface-mount assembly processes given the 6-SMD Gull Wing package. Ensure circuit design accommodates the specific photovoltaic output characteristics and isolation voltage requirements.
Part Context
This component belongs to the optoisolator category, specifically utilizing photovoltaic output technology. It serves as a signal transmission device that maintains electrical safety through high-voltage isolation. The 4N273S represents a surface-mount variant within onsemi's historical portfolio of isolation devices.
Replacement Considerations
Similar substitutes include Vishay Semiconductor Opto Division's 4N27-X007 series. Verify pinout and electrical parameter compatibility before substitution.
