MV2N4091UB

Overview

The MV2N4091UB is an N-channel Junction Field-Effect Transistor (JFET) manufactured by Microchip Technology. It utilizes silicon technology and is housed in a TO-18-3 metal can package designed for through-hole mounting. The device features a single configuration with a drain-source breakdown voltage of 40 V and a gate-source breakdown voltage of -40 V. Key electrical characteristics include a zero-gate-voltage drain-source current of 30 mA, a continuous drain current of -100 pA, and a drain-source on-resistance of 30 Ohms. The component supports a power dissipation of 360 mW and operates within a temperature range from -65 C to +175 C.

Procurement Notes

Verify the specific suffix 'UB' against official Microchip documentation to confirm exact binning or testing criteria, as suffixes often denote specific performance grades or packaging variations not always detailed in generic summaries. Ensure the procurement channel provides valid traceability and authenticity guarantees for military-grade or high-reliability components. Confirm RoHS compliance status directly with the manufacturer, as indicated by the 'N' designation in available data.

Selection Notes

Select this component when a ruggedized, hermetically sealed JFET is required for high-temperature environments up to 175 C. The TO-18-3 package offers superior thermal and mechanical stability compared to plastic packages. Consider the 30 mA IDSS and 40 V breakdown limits to ensure compatibility with circuit biasing requirements. Verify that the through-hole form factor aligns with the target PCB layout constraints.

Part Context

The MV2N4091 series belongs to Microchip's lineup of silicon N-channel JFETs. These devices are part of a broader family of discrete transistors designed for analog and RF applications. The MV prefix typically denotes a specific manufacturing line or grade within the company's transistor portfolio, emphasizing reliability and consistent electrical parameters across production batches.

Replacement Considerations

Cross-reference with MX2N4091UB for potential functional equivalence. Verify pinout compatibility and electrical parameter tolerances before substitution. Consult official Microchip datasheets for both parts to confirm interchangeability regarding package dimensions and thermal characteristics.
