JANTXV4N48

Transistor, Photovoltaic Output Optoisolators Overview

The JANTXV4N48 is a single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It utilizes an NPN phototransistor output and is housed in a hermetically sealed TO-78-6 package. The device provides an insulation voltage of 1000 Vrms. Key electrical parameters include a collector-emitter voltage of 40 V, a maximum collector current of 50 mA, and a power dissipation of 300 mW. The current transfer ratio ranges from 100% to 500%. Operating temperatures span from -55°C to +125°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific JANTXV suffix indicates enhanced reliability standards compared to standard commercial variants. Confirm RoHS compliance status as required by project specifications. Ensure the TO-78-6 package dimensions match the target PCB layout. Validate that the manufacturer documentation supports the intended military or space-grade application requirements before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high reliability and hermetic sealing are mandatory. The TO-78 package offers superior protection against moisture and contaminants compared to plastic packages. Consider the 1000 Vrms isolation rating for high-voltage separation needs. Evaluate the 100% to 500% CTR range for circuit design margins. Ensure the operating temperature range meets the environmental conditions of the deployment site.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the JANTXV series of optocouplers designed for harsh environments. The JANTXV designation typically signifies screening according to MIL-PRF-38534 or similar high-reliability standards. It is distinct from commercial equivalents like the 4N48 by its packaging and quality assurance processes. The family focuses on providing robust optical isolation for critical applications where failure is not an option.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the TO-78-6 hermetic package and JANTXV reliability level. Standard commercial TO-78 or plastic package optocouplers may not suffice for qualified systems. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage. Consult manufacturer cross-reference guides for approved equivalent parts within the same reliability tier.
