JAN4N23A

Transistor, Photovoltaic Output Optoisolators Overview

The JAN4N23A is a high-reliability, single-channel transistor-output optocoupler manufactured by TT Electronics/Optek Technology. It features an NPN phototransistor output with a base terminal for enhanced switching speed control. The device provides electrical isolation of 1000 Vrms between the infrared LED input and the collector-emitter output. 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 10 mA forward current. The typical rise and fall times are 15 µs to 20 µs.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to historical military specifications. Confirm lot traceability and compliance with relevant quality standards such as MIL-PRF-38534 if applicable. Check current manufacturing status as some variants may be obsolete. Ensure proper handling procedures for leaded packages during assembly to maintain reliability.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and controlled switching speed are critical. The integrated base allows for faster turn-off times compared to standard variants without base terminals. Consider the TO-78-6 package size for board space constraints. Verify that the 35 V collector-emitter rating meets the load requirements. Evaluate thermal dissipation capabilities within the specific application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

The JAN4N23A belongs to the 4N23 family of optocouplers, which are widely recognized for their reliability in isolated signal transmission. It serves as a bridge between low-voltage control circuits and higher-voltage power stages. The JAN designation indicates adherence to strict military-grade quality standards, distinguishing it from commercial equivalents like the standard 4N23.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitutes include JANTX4N23A and JANTXV4N23A, which offer similar functionality with potentially different qualification levels. Standard commercial alternatives like the 4N23 may lack the required reliability ratings. Verify pin compatibility and electrical parameter margins before substitution.
