JANTXV4N24A

Transistor, Photovoltaic Output Optoisolators Overview

The JANTXV4N24A is a military-grade, transistor-output optocoupler manufactured by TT Electronics/Optek Technology. It features a single channel with an NPN phototransistor output and a dedicated base terminal for improved switching performance. The device utilizes a hermetically sealed TO-78-6 metal can package designed for through-hole mounting. Key electrical specifications include a minimum current transfer ratio of 100% at 10 mA forward current, a collector-emitter saturation voltage of 300 mV maximum, and a high isolation voltage of 1000 Vrms. The unit supports a maximum collector current of 50 mA and operates within a temperature range of -65°C to 125°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Hermetically sealed TO-78-6 metal can construction ensures reliability in harsh environments
• Integrated base terminal on the phototransistor output enhances switching speed and stability
• High isolation voltage rating provides robust electrical separation between input and output circuits
• Military-grade qualification meets stringent environmental and performance standards

Transistor, Photovoltaic Output Optoisolators Applications

• Military aerospace systems requiring radiation-hardened or high-reliability components
• Industrial control systems operating in extreme temperature conditions
• High-voltage isolation interfaces in defense communication equipment
• Critical safety circuits where component failure is not an option

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix 'TXV' corresponds to the required military grade and hermetic seal specifications for your application. Confirm that the TO-78-6 package dimensions match your PCB layout constraints. Ensure that the procurement source provides traceability documentation consistent with military procurement requirements. Check for any specific handling instructions related to the hermetic seal integrity during assembly.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when military-grade reliability and hermetic sealing are mandatory. The integrated base terminal offers superior switching characteristics compared to standard variants without a base connection. Consider the TO-78-6 package size if space allows for larger through-hole components. Evaluate the 1000 Vrms isolation capability against the system's voltage requirements. Ensure compatibility with the -65°C to 125°C operating temperature range.

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 indicates Joint Army-Navy specification compliance, while 'TXV' denotes a specific military grade variant with enhanced testing and hermetic packaging. This series is widely used in applications demanding high reliability and long-term stability under severe environmental conditions.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The standard commercial version 4N24A may serve as a functional substitute if military grade and hermetic sealing are not required. Verify that the non-military variant meets the same electrical parameters, particularly the current transfer ratio and isolation voltage. Ensure the package type and pinout remain compatible with the existing design.
