JAN4N22A

Transistor, Photovoltaic Output Optoisolators Overview

The JAN4N22A is a military-grade, single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features an NPN phototransistor output and utilizes a hermetic TO-78-6 OCI package for collector isolation. The device provides 1000 Vrms insulation voltage with a maximum collector-emitter voltage of 35 V and a peak collector current of 50 mA. Electrical characteristics include a forward voltage of 1.3 V at 10 mA input, a power dissipation rating of 300 mW, and a current transfer ratio of 25%. Switching performance is defined by rise and fall times of 15 µs each. The component operates within a temperature range of -55°C to +125°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific JAN (Joint Army-Navy) grade certification requirements against your design specifications before procurement. Confirm that the TO-78-6 OCI package dimensions are compatible with your PCB layout or chassis mounting constraints. Ensure that the supply chain source can provide valid traceability documentation required for military applications. Check for any recent PCNs regarding material changes or manufacturing site transfers that may impact qualification status.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when hermetic sealing and strict military environmental standards are mandatory for the application. The TO-78-6 package offers superior thermal and mechanical stability compared to standard plastic packages. Consider the 15 µs switching speed limitations if higher frequency data transmission is required. Verify that the 300 mW power dissipation rating accommodates the thermal conditions of the final assembly environment.

Transistor, Photovoltaic Output Optoisolators Part Context

The JAN4N22A belongs to the Optek/TT Electronics family of transistor output optocouplers. It serves as the military-grade counterpart to commercial variants like the 4N22A, distinguished by its hermetic metal casing and stricter quality assurance protocols. This series is designed for applications where long-term reliability under extreme conditions is critical, differentiating it from general-purpose industrial optocouplers.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The commercial equivalent 4N22A shares similar electrical parameters but lacks the hermetic military packaging. Substitution requires verification of environmental compliance and package footprint compatibility. No other direct public substitutes are confirmed in the provided documentation.
