JANTX4N23

Transistor, Photovoltaic Output Optoisolators Overview

The JANTX4N23 is a single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features an NPN phototransistor output with a base connection, housed in a TO-78-6 hermetic package designed for through-hole mounting. The device provides high isolation capability with an insulation voltage of 1000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 35 V, a maximum collector current of 50 mA, and a forward voltage of 1.3 V at a forward current of 10 mA. The unit exhibits rise and fall times of 15 µs each, with a maximum collector-emitter saturation voltage of 300 mV.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific order matches the JANTX4N23 designation rather than similar variants like JANTX4N23A, as suffixes may indicate differences in testing or specifications. Confirm RoHS compliance status and datasheet revisions prior to procurement. Ensure the supplier provides traceable documentation for this military-grade component.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a hermetic TO-78 package is required for radiation or environmental resistance. Choose based on the 35 V collector-emitter voltage limit and 15 µs switching speed. Consider the base pin availability if external linearization or faster switching is needed compared to standard open-collector outputs.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the JANTX series of optocouplers from Optek/TT Electronics, which are characterized for high reliability. The JANTX4N23 specifically utilizes a silicon planar epitaxial structure. It is distinct from non-hermetic plastic packages and offers superior thermal stability and moisture resistance compared to standard commercial equivalents.
