JAN4N24U

Transistor, Photovoltaic Output Optoisolators Overview

The JAN4N24U is a transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features a single channel configuration housed in a surface-mount LCC package measuring 4.32x6.22 mm. The device provides an isolation voltage of 1000 VDC and utilizes an NPN phototransistor output with a base terminal. Key electrical characteristics include a minimum current transfer ratio of 100% at a forward current of 10 mA, a maximum collector-emitter saturation voltage of 300 mV, and rise/fall times of 20 µs.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Integrates an NPN phototransistor with a dedicated base terminal for enhanced switching control
• Designed for surface-mount assembly to facilitate automated PCB manufacturing

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring signal isolation
• Solid-state relay driver circuits
• Microcontroller interface isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'U' corresponds to the required surface-mount LCC package variant rather than the through-hole TO-78 version. Confirm RoHS compliance status and check for any recent product change notices regarding pinout or material composition updates from the manufacturer before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount form factor is mandatory for space-constrained designs. Ensure the application voltage does not exceed the 1000 VDC isolation rating. Consider the 20 µs switching speed limitations compared to faster logic-output alternatives if high-frequency data transmission is required.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the 4N24 series of transistor output optocouplers. While the standard 4N24 typically uses a through-hole metal can package, the JAN4N24U variant specifically adapts this circuit topology for surface-mount technology. It shares functional similarities with other devices in the 4N22-49 family but offers distinct packaging advantages for modern PCB layouts.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the standard 4N24 for through-hole applications and the 4N24A for equivalent performance in different packages. Verify pin compatibility when replacing with generic equivalents.
