Transistor, Photovoltaic Output Optoisolators datasheet and documents for ISP621-4XG
Transistor, Photovoltaic Output Optoisolators Overview
The ISP621-4XG is a quad-channel phototransistor optocoupler in a 16-pin DIP package. It provides galvanic isolation with a rated voltage of 5300Vrms and a collector-emitter voltage of 55V. The device features an infrared LED input and NPN silicon phototransistor output. Key electrical parameters include a maximum forward voltage of 1.3V, typical rise time of 2μs, and typical fall time of 3μs. Operating temperature ranges from -30°C to 100°C.
Transistor, Photovoltaic Output Optoisolators Feature Summary
- Four independent channels for high-density signal isolation
- Galvanic isolation between input and output circuits
- NPN silicon phototransistor output configuration
Transistor, Photovoltaic Output Optoisolators Applications
- High-density digital signal isolation
- Microprocessor system interfacing
- Industrial control circuit isolation
Transistor, Photovoltaic Output Optoisolators Procurement Notes
Verify the manufacturer designation Isocom Components 2004 LTD against official documentation. Confirm the 16-DIP package type and channel count match project requirements. Ensure the 5300Vrms isolation rating meets safety standards. Check for RoHS compliance if required by specific regulations.
Transistor, Photovoltaic Output Optoisolators Selection Notes
Select this component when four isolated channels are needed in a single package. The 55V collector-emitter voltage suits low-voltage logic interfaces. Consider the 2μs rise time for moderate-speed digital applications. Verify thermal limits for operation up to 100°C.
Transistor, Photovoltaic Output Optoisolators Part Context
This part belongs to the ISP621 series of phototransistor optocouplers. It is functionally similar to the TLP621-4GB but manufactured by Isocom Components 2004 LTD. The series offers quad-channel isolation in standard DIP packages for general-purpose electronic circuits.
