JAN4N24A

Transistor, Photovoltaic Output Optoisolators Overview

The JAN4N24A is a high-reliability transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features a single channel with an NPN phototransistor output and includes a base terminal for improved switching performance. The device provides 1000 Vrms isolation voltage between input and output circuits. Key electrical parameters include a minimum current transfer ratio of 40% at 10 mA forward current, a maximum collector-emitter saturation voltage of 300 mV, and rise/fall times of 20 µs. It operates within a temperature range of -65°C to +125°C and is housed in a TO-78-6 metal can package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as JAN4N24 or JAN4N24ATXV may exist within the product family. Confirm that the required current transfer ratio meets the 40% specification rather than assuming higher generic values. Ensure the procurement source provides traceability documentation appropriate for high-reliability components. Check RoHS compliance status if environmental regulations apply to the final assembly.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and fast switching are required in harsh environments. The integrated base allows for external biasing to reduce storage time. Consider the TO-78 package constraints for PCB layout and thermal management. Compare the 40% CTR against system requirements to ensure adequate noise margin. Evaluate the operating temperature range to confirm suitability for extreme conditions up to 125°C.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the 4N24 series of transistor output optocouplers from TT Electronics/Optek Technology. The JAN prefix typically denotes a military or high-reliability variant of the standard commercial 4N24 device. It shares functional similarities with other devices in the 4N22-24 and 4N47-49 families but offers specific reliability enhancements. The TO-78 package distinguishes it from plastic封装 alternatives like the DIP-6 versions.
